Default T140 Bonneville street tracker-kind of mix project ODDISEY

Prologue
A dream come true.
18 years waiting for the opportunity to have a Bonneville.
In this country (Uruguay in S America) there are only 7 (8 now!) Bonneville (stock) 1978 T140 and 1 T120.
For 15 years I have been driving a 1948 500cc.


- Long story short:

In the middle of last year I bought a basket bottom end in Florida (USA); the main loop, rear frame and swing arm were bought by EBAY. When the box arrived at the agreed address at the other end of the USA, the postman served an intoxicated person who told him that was not for there and returned to sender ... so again I had to contact the seller to send it again but now to send to a warehouse of a logistics company.
Then contacted with an export company to succeed in getting a ship (cheaper than by air) and go to find the pieces to the home of a friend in Miami Beach.
Finally, when the cargo appeared the engine and frame were sent to Montevideo Uruguay
After 25 days the packages were on local port but Customs would not let me enter the stuff to the country.
That was in December last year
The customs broker told me I finally could not enter the goods.
Within months, got another customs broker and told me that the only possibility would be to send its to a free zone and there can be disassembled to enter the country as spares parts ...
That was 2 ½ months ago.
A couple of weeks since I have it and have begun work on a future bike.

So I decided to start this thread because there s not too many on later bonnie ´projects

You poor bastard. That is so much crap to go thru, glad you stuck with it & are finally getting to get to have some fun now.

Is it something you can get tags for later when done with out a big problem?

Yes, keep posting as you go, The bike probably could not have landed in better hands it sounds like.

...2 1/2 months ago, when I went to the free zone to tear it appart the bottom end, actually we were there on 2 bikes; that 500 pre unit showed above and a ´64 unit 500cc so we put saddle bags full of tools on the bike with swing arm and drove about 700 Kms in that day to go and to drive back.

---

Bear in mind that Im not a mechanic so may be some post will sound kind of dumb in techniques or what I trying to show...


I have the 4 screws early rocker boxes
The arms are in very good shape, the boxes too.
I used a bit larger (than the spindle head) tube and pushed a bit the vise to "unlock" the spindles, then tapped slightly.

...when we went to the free zone we left the camshaft in their places
so now I m pulling out both
The pinions seem to be the early type due to the A B letters stamped and not the notches that came in later models

Im using an universal extractor because I don t have any special tools.
I put couple of screws with washers to do the job.

...so I have a 71-2887 intake camshaft
and a 71-0042 exhaust one
with the pinions stamped with A B instead of the marks.
Those pinions are pre ´75 and
that exhaust camshaft is not an stock part number for any T140 or T120
but I think that is a number for a blank camshaft to regrind...

I dont know if any of you with a ´79 Bonnie have the same ones
you know, if the previous owner changed the pinions may be changed that exhaust camshaft too.

Also I have there a three phase alternator
that will be good cranking RPM s but I dunno at low...

What s your opinions?

BTW that -48 is pretty sweet too!

...thanks SwedeBobb.

Besides the questions about those camshaft I have more doubts for you T140E owners.
I dont have any of the head studs and bolts
I have the parts number and dims of most but I just put the head and the rocker boxes on the cyl to take measurementswith a calyper, and I found very different lengths than the book

plus I really do not understand the length of the (4) 3/8 rocker boxes bolts.
I mean, there are very short; where these bolts screw?
You have to pass all the way the boxes then the head to finally find the Cyl threads...thats a long way for a shortie...more than 5 inches!!

In the workshop manual I have a dissection diagram showing assembly of cyl head studs
but is not clearly well explained.

Hope some of you can add a bit of info about it.

thanks

The rockerbox bolts screw into socket headed tubular nuts that screw down onto the cylinder head studs.

...hey fellas I have a stupid problem with the rear hub and the bearings
I have the old hub type from mid 40s to early 70s in some models.
I dont have the bearings so I m taking measurements and see that the hub internal diameter where the bearing is located is 44.3mm or 1 3/4" but the bearing part number is: 37-7042
and that is a mm bearing: 47 x 20 x 14
¿?¿?¿? bigger than the hub itself?

I rang several bearing dealers and say that exist that and previous is 42 x 19 x 12
smaller so I need to make a sleeve
or a roller bearing 45.2 x 19.05 x 15.2
in this case I need to machine the hub almost 1mm to fit..

so how in the world the part number is incorrect?

what you guys put on your bikes?

really appreciate your responses
Im in the middle of nowhere regarding Triumph parts

...still trying to figure out this thing about the rear hub and bearings

in the meantime I disassembled the fork.
Its a ´76 fork and after the inside inspection, have all the parts but looks like bottom ended
however the springs got the same length as book described, 1/4" more actually
may be its in need of more oil?

...hello, few weeks without updating this thread but I have been very busy with my job (building surfboards) among life...

the oddisey continue:

-still I couldnt start to build the engine because the parts that I ordered from UK were sent me wrong...
I specified very clearly and with numbers, etc; several e mails but without luck
3 UK shops did the mistakes!
I ordered STD shells and sent me .40!!
An SKF roller bearing NUP and sent me whatever
A 40 holes stainless rim set to 1 cross but sent a 36 holes...
Lot of money in customs taxes
I returned some things and still waiting to the correct stuff to arrive.

By the way, I bought an Avon speedmaster (made in UK) that in my opinion looks better than olders that I d seen
plus the tube is nice quality.

-No chroming shop in my little town; those shops are in Montevideo that is a city at 230 kms from here so I sent the engine to polish and the guys lost the points cover...plus a friend who went to pick up the motor scratched (in transit) the surfaces in several little places, that I need to re polish some of these days.

...quite slow this project due to couple of things: my other Triumph broke 1 of the con rods so Im now in major overhauling and all the extra money and time go there.
And still the UK shops send wrong stuff
here s pictures showing 2 exhaust tappet blocks

I need opinions about to put these 2 instead of one inlet one exhaust.
The inlet ones have the smooth sides.
I do not see any problems but I do not want to fuck up everything

...in the meantime I re polished the cases, etc. I have a friend who s a jeweller, so I asked to use his small polish machine to do the job.

Also the polish shop forgot to sand and polish a part from the driving crankcase so I ll do in next days.

First I worked the stuff with those compounds that look like a candle, but scratched the surface too much; possibly because I sanded to 2500!
then I worked with the pastes that I use for the surfboards and was all good without marks, etc

...hello,
so I m cleaning the cases to put the bearings.
I ll put a 3 piece roller bearing as fitted in the mid ´80s Bonnies.
I have a question about the "washer" piece of the bearing to what side is fitted...I mean is to the case or to the crankshaft or even between the inner cage and the rollers?

Hope some one can help about it

thanks

The inner race goes on the crank with the lip towards the cheek, and the "washer" goes in the case BEFORE you install the outer race. I'll try to post a photo.

...ok, so in the future, if I pull out the crank only the inner race stay in the crank, the other 2 parts will un move in the case.

Cool if you have pictures to post too.

reverb,
check out northern eagle cycles. they have probably all of the precise head hardware you need. if you have questions , the owners name is Dennis, he's a straight shooter. I have a 140 E and a 140 D. that practically makes us related, kidding , good luck, coming along nicely.

Mine had letters but they were facing the inside of the timing case.
Timing was references by a series of dots and dashes. Dont know about other year cams, possibly a different duration, there were three different options in 79 alone, good luck hope the photos help.

+1 on Norther Eagle Cycles. I have ordered a fair amount from them this year and shipping is always fast. Another place you may want to check is British Cycle Supply. Super helpful and have an impressive stock list. They ship out of Canada and the US, which ever side of the border you are on.

...Hello Pkcoon, thanks man, I ll update the blog sooner too.

Hello Ski, talking about the head hardware, I solved that some weeks ago, but I have a question to you about the ones that hold both cases on the bottom. Are they bolts? or are studs?

by the way, I do not have problems with the timing...yet.

thanks in advance

Hey Swiseman, I m a Brit cycle customer from pre commercial internet, thanks

...ok Ski, hope is not ask too much if you can check in the bottom of your T140E in which holes go the studs and in which the bolts?
As you know, there are 3 5/16" holes and then a big 7/16".

thanks

the 7/16 at the bottom is a stud and spacers that act as a motor mount
the other 7/16 is a bolt that is a mount on the downtubes
not entirely sure itf the exaust steadys are a stud or bolts
the rest of them 3/16 are bolts
I think , see attached

Reverb,
I promised you pictures of a timing side roller bearing conversion:

Here's the inner race on a crank:



And the outer race/washer from the outside of the case:



And the inside of the case:

...hello Ski and Eric, very helpful; thank you very much.

-Ski, about the bolts and studs, now with the pictures is better to understand, for ex.: the spacers on that bottom stud, because in the parts book the draw in page 46 fig 18 is not right and there s a bolt not a stud (but the part number is for a stud) and 1 spacer (right say) is showed not both ¿?; the other spacer is showed as a thicker washer...so was complicated to know exactly the positions.
Also, in the same page there s a bolt (7/16 x 4) that say "motor fixing front" that have that big spacer (left say) and the right spacer is like the other, a thicker washer ¿?
Where s the place of that bolt? because all seems 5/16"

...very late with the updates, but as previously commented, I put my free time and money to rebuild the pre unit motor, I just finished few weeks ago, so now Im on the road again (well, I was using my Vespa style scooter to take the road...)

anyway, here some photos about doing the crankshaft plug.
Cut the head of an Allen screw, then Bronze was used.

...more nightmares...due to the broked conrod that I had on the pre unit I decided to buy new pair for this engine; not necessary you would say.
So I have new con rods, new shells, and checked the crankshaft with a micrometer and have the STD measures that the manual say and seems that is not oval.
when I started to put the new conrods, one is in a perfec fit with the torque set of 22lbs, the other failed to fit well, not have a "free", lose movement.

-Also, the conrod sports a not centered "hole", is kind of thinner (the material) in one side of the ("shoe"-the bottom part-).

So another thing that the British shops sent me wrong.

-Some say to use a fine grit sandpaper, like 2000 or 2500 grit or scuff with aluminum sponge in the small bearing areas where seem problematic

Is that a safety procedure?

thanks in advance

...well, no opinions so I decided to go with the aluminum fibers (the ones that in the past the grandma uses to polish tins)
I did some test with 2500 grit sandpaper and 3000 grit (that s the finer grit) and the aluminum wool seems finer yet; so I passed, with Kerosene, a bit on the problematic areas, clean and polish with a paste; clean again and fit on the con rods, torque set and see; then again until the conrod was fine on the crankshaft.

-Also I tested the original conrod with the old shells but lack of movement as the spare conrod...very strange I must say.

Then I removed the outer race welding a rod and a hit with a hammer.

...I tell ya that almost impossible to fit some items without a press...
In this case, the part of the bearing that goes to the cases, fits without hassles by hand without any force after heating
but the parts that go in the crankshaft is not possible to fit without a press.
The inner race in the triple roller bearing was too tight.
-I did a "pile" of sockets to apply the press, due to the shaft

-I put as per the "late" book, a C2 and C3 clearence roller bearings.

...hello Ryanm, yes, I ll try to put some of the steps due to the real difficulties that any one can find.
I mean, I have w shop manuals, owners manuals, Haynes manuals, the Wes DVD and I tell ya that NEVER is an easy task, like those manuals say...you always in need to improvise something
I know a lot about it from my ´48 pre unit...so old and with miles that when you rebuild you need lot of experience or friends who are mechanics (real ones) and know the stuff to solve problems (a lot!)
Also, you really need ALL the tools; more in the old pre units.

Hello Redasphalt3, thanks

--I see that the 750cc do not have oil seal in the drive side of the crankshaft but what happend with the dust or "residue" of the clutch regarding bearing??

Also, what s exactly these 3 tiny holes do? help with the air release? Im asking because if you do not have oil seal why you want those holes?

thanks

Hey, good on ya,for all your efforts. Wish I could give some insight, but have Zero experience with Triumphs. I would think (hope) that others would post. I know there has to be some knowledgeable Triumph guys on here. I really feel for you, as it seems to be a struggle to get parts (the right parts anyways) in the remote area you're at. Good luck, and keep posting!

Nice engine work. It brings back memories of when I build my Triumph engine. That sure does seem like a long time ago now!

The 750cc's don't have an oil seal because the crank and primary share oil. The 3 holes lets the oil equalize between the primary and the sump.

Are the 650s the same? It seems crazy for it to share crank oil with clutch oil doesnt it? Is this why the sludge traps are always so nasty(clutch fiber residue)?

I build T58 turbine engines for the USMC, and we do this. We heat any press fit bearing races in the oven to push them on shafts, and we freeze seals to pus them into cases. Our bearings are never heated over 300 degrees, it'll degrade the intgretity of the bearing. And when your talking a turbine engine making 2200 shaft hp and spinning 28000 rpm, you want it perfect. This bike build is coming along great, you went through more hell than most would to get it man. Keep up the good work

...hello Ski,
yes, as in the pictures, the part that goes in the halves fitted without effort but the races to the crankshaft are not possible to heat...so there the press is the solution to not damage anything.

-Danboy, thanks

-Justrob, I see why those are so tiny and are bellow the bearing...however still you have the rod bearing shells contaminated with clutch oil

-Crawler07, possibly due to that they put an oil filter on the line.

-Spots, again, the races to the crankshaft are instantly done with a press without any damage.

-Richard D, keep passing

Here s few pictures with the crankshaft installed and the timing set up:
*as mentioned in the first page of this thread, the motor came with the old timing gears, the ones with A - B letters.
*I trimmed all the silicone excess.
*The bolts and nut are stainless steel, so I used the oil that comes with the spokes to torque them

the best way is to use an old timing pinion placed between the camshaft pinion and intermediate wheel. works for both removal and instellation.

I believe your motor breathes its excess pressure through the primary breather..... so not only do those three holes allow the passage of fluid but also is where your crankcase breaths through. You run the same oil in the engine as in the primary. Whatever it calls for.

...Dan boy, I know your feeling but in this case was pretty simple with no pain due to the long and powerful cricket.

-Hey Buddhistpunk77, what s exactly the way you put that pinion? I do not see any place between those pinions or you say replace one of the pinions then put the old one, etc?
but in that case, how do you use this to remove it?

-96dragginsdime, my gut feelings is with the con rods shell bearings...
seems that an oil filter is mandatory

--I noticed about rotary oil pumps for Triumph s in 1998 or so. I decided that when a T140 engine appeared, I would buy one so in 2009 I bought it from a UK shop, but in all these years from time to time I checked and have been seeing that nobody want one really and a lot of bad stuff going on like oils seals damaged; do more holes in the release valve, etc etc
Finally I emailed Morgo and said that I have a rotary one new in an unopened package that I ordered from x shop there and I want a piston one in exchange no matter if the cost is a half...my loss. They checked the number on the pump and in their data compared and saw in which (!) shop I bought the pump and say yes. Few weeks later they sent me the other pump and a t shirt with the international shipping paid too

Lucky Lindy, yeah, it s that Grey thing that shades a bit there

Ironhead Slim, well man, I dunno, Im trying at least

BY THE WAY: WHY the tappet clearance in the T140 s is the other way round than logic?

I read that s because very different cam lift but logically the exhaust have more clearance...

...what I try to say is as per the manual the t140 have 0.008" inlet! and 0.006" exhaust¿?
Ok, I can understand that lift thing on the cam but still goes counter logic...
(t120 is 0.002 inlet and .004 exhaust)
Do you have opinions on that?


--I forgot to mention that the tappets were a pain to put into the blocks.
When the blocks and tappets were outside the cyl barrels, I checked that everything was smooth and ok; After put the blocks on the cyl the fuckers did not enter anymore!. I spent around 5 hours "smoothening" again.

--In which tool the factory thought when did the cyl mould?
I mean, there s no wrench to adjust tight the 12 point nut showed (left one). I have an ultra thin Bahco wrench that adjusted the other ones but impossible to adjust very tight this one.

I think that Ill cut an open cheap 1/2 wrench and see what happend.

Nice build so far, those polished cases are intense! Did those federal mogul rings come with a 3 piece oil ring? Don't get too crazy with oil in the cylinders, you want those rings to bed in.

Can you grind that wrench down some to fit in behind that nut?

Okay thanks. I used some Hastings rings with chrome top ring and 1 piece oil ring on a recent engine build. Not impressed. One cylinder looks to be getting oil past the rings. Let us know how those rings work.

Not sure, but I think federal mogul is making AE rings now.

...Federal Mogul is a conglomerate, like VW is the owner of BMW, etc.

Still waiting for opinions on the tappets clearances.
In the meantime I put the engine on the frame until the fucker be heavier to draw the basics to build the rear engine/frame plates.
Im guessing here; I mean, I do not know if the platyes are straight or have some foiling to accomodate something. Remember that the bottom end is 79 and the frame 67; fit, but a bit different possibly or may be not...
I think the rear frame is somewhat twisted but might be due to not bolt there...I do not know.

The only other option I can see is for you to make more nuts up that will take an open end spanner like you already did.

...Hey Dan boy, so with those welded supports still the wrench fit in that tiny space?
the nut is almost on the jug wall.

-I have another very distinctive and different t140 characteristic question:

A Factory bulletin from 1979 say that with the composite head gasket you should torque to 22lbs the 3/8 and to 18 the 5/16
then run and retorque to less!!! (the ones that are in the manuals that have the copper gaskets...) to 18 lbs the 3/8 and to 16 the 5/16

!!!!!
please somebody that used these gaskets what are the experiences?

thanks in advance.

...well, seems that nobody have an opinion on that...

I have pictures reassembling the box; I noticed different treatment in the Triumph s boxes; the pre units are easier to assemble all the pack as the unit 650s; the unit 500s, the gears pack, the selector and even the inner cover, etc and these 750s better one by one.

-Aligned the top of the second thoot with the foot change spindle bore.
-Also, the camplate is better than the 650s because you can put it or pull out without molesting the 5th gear, etc

...I decided to continue with this thread but seems that there s not too much interest.
I have been seeing that the interest in this board is more prone to threads that have welding, do changes, etc on frames, tanks..
My perspective is from a rider that is building a "new" ride with most of the problems found in rebuilding a motor (and then the bike) to facilitate for another buddy out there to easy see where those problems are
so it s not only put pictures and follow with it
a few words describing or asking about a determined step or that the thing is not so simple as a video or manual can show; the "real life" is more difficult
Also, this one is complicated due to is a basket case not a complete bike to start.
Hope still many of you are interested.

thanks

Hey Reverb, you shouldn't be discouraged just because people don't post on your thread. That happens a lot on my build thread and I find that a lot of people just look but don't post. You can be sure that when you get further on with this build people will post when you have some design decisions to make.

You have nearly 8000 views already!

Anyway, I'm looking and posting, does a guy need any more?

Cheers Dan.

...thanks for the encouragement; in this virtual world sometimes, you do not know exactly what s going on...

-the head was done by Wes W. about 2 years ago or so
I decided to pull out the valves and clean everything again.
I noticed these washers, but not the same washers in the 4 guides; 3 have the normal washers for these applications the other have a thin plain (smooth) washer so I started to measure the length of the springs to check everything is right
I do not remember but I guess these springs are new, at least have the color dots in Green and Red, so I do not understand why not all have the same length...
I suppose that Wes did the correct thing.

So I used this homemade tool to put the valves; I used 2 sockets and a wooden block under; very easy in this way, lot easier than with the C clamp
Valves and guides are Rowe

That is a great tool you made up there. You should post that in the homemade workshop tools thread.

Keep the pics coming.

...thanks Dudley and Dan
simple yet efficient tool in a cheapo way.

-I put the clutch and alternator
I see that there s an error in the design, due to the stator and rotor were previously designed for the double chain but no for the triple chain and there s a gap so the stator fit not really well under the rotor in the 750s at least in the T140E shaft

-I studied all the possibilities with the pushrod tubes and their O rings included the thicker square one (clear White)
The best combo I found, due to the head clearance regarding the gasket (in a dry fit)
was the Black on top the Orange inside and another Black with silicone in the place of the clear white
I used vaseline instead of grease with the O rings
-I had to file the cyl barrels to proper fit the pushrods

...hello and thanks to everyone:
-Killswitch,Dvrogers, Astek, Meathead, Indiana kid, Dan, Bobash.

Ok, finished the motor the other day; took me around 12 days (but not in a row). These thing is not so fast due to I have it in another town at around 25kms from here and of course, my daily work, but I drive happy these kms on my pre unit to rebuild this other motorcycle.


-I cut an Allen key to torque the two 5/16 nuts in the middle of the head. I noticed that, at least with these earlier rocker boxes, you cannot put those nuts before to torque em down; or you can file a bit the boxes to do that. If not, you should put one first then the box, then the other.
Possibly this do not happen with the later type of boxes (the ones with the 6 screws on the little covers)
-Couple of years ago, after asking here, I ordered from Canada and UK, one of each studs, to have a sample to made the others in a lathe.
This way, cause all the studs+shipping+customs taxes, is too expensive for these stuff.
Those middle socket nuts are not possible to do with a lathe so I bought them.
I do not have pictures of the head in place, but as mentioned in the other comment, I checked all the possibilities with the O rings, prods tubes, gasket and head so I tried to obtain less than .0030 of light between the head and the gasket until apply torque.

...I did not time this month to work on the motorcycle but now I finished with the front end (wheels, forks, etc)
Here some photos of the wheel:
-rim and tyre from England, spokes, nipples from USA, homemade hub.
-I tried my best polishing the wheel because came unpolished.
-I laced more than one time but Angel from Buchanan helped me a lot.

...I have time to post the other photos of the front end.

-the fork spacers were done hollowing a bar. I use the 2" and cut the springs 1/2 less, as per Scraper thread, but I found that the forks still is too much tall..
May be I put the spacers on the wrong side? I put them between the small spring and the bottom of the fork. Please check the picture.

The frame still is around 5 3/4" from ground. My pre unit is at 4", but I do not remember the way I took that time...long ago, I only remember that I cut the frame tubes, but now I do not want to cut...

How do you guys do to low these frame loops? (67 T120 front loop)

I put the rear frame in the limit of the distance from ground (not showed in that photo)
I want the frame parallel to the ground
If I do 3" spacers and cut again the springs, still Im very far from 4" clearance...
and may be too preloaded those springs, so too tight¿? and might be bottomed up¿?

-I put around 62Kg of weight to emulate the engine and only down 1/4" !! even with me sitting on the frame..

--I had the fork tubes warped (bend) so I used the lathe to perceive the errors then used the magical tool to straight them.

---the frame is older than the forks so the key lock do not fit properly, so I cut the tab and relocated properly. Before that I went to a locksmith to make a key for the drum.
--I cut the fairing tabs too.

...hi all, many problems here, one is that the mother board of my PC is broked down..but here s few more photos to share.


-so I dismantle the forks again, put 3" spacers instead of the 2" ones and cut the springs 1" more, put weight similar to the engine and me on the frame and still I have more clearance on front part of the front loop than the rear part of the loop...

-Cut the swing arm and added 2 inches; I used a solid piece of steel; 2"+1 1/2" more in each side, then 2 holes per side to let the bronze (of the welding) squeeze pretty well; the joints were welded with electrodes.
I have cell pictures of that process but here s the one welding with Bronze.

-the rear frame is too wide to have a custom seat and "fight" visually with the slim line gas tank so I decided to cut it.
I used the same tubes, changing the curves, etc, then weld them in a similar way the factory did.
Also I lowered 1" the stance of the future seat.
Next thing is cut that chromed rear part and make some changes there.

...so I decided to put the engine (t140) to see what I do with the oil tank etc
the fucker did not fit on the 67 frame...
I tried in different ways included the way DANBOY did in his build (engine to frame)

I m trying to avoid untorque de boxes...
The only thing comes to mind is untorque rear rocker box and see what happend
You know, as previously mentioned in other comment, the boxes do not pass lose against the middle head screws...so is a pain in the arse to unscrew those then put the stuff then all over again to unfit the engine to weld, paint, etc...
not good torque and retorque again and again...

may be some of you have experience on that; t140 engine (that is a bit shorter) and 67 T120 frame

plus I scratched a lot the polish on the fucker

Hello Danboy and Ryanm, well I have my PC broked so Im in a cybercafe...

For the record the complete engine do not fit in a 67 frame;
Danboy, I tried your method but did not work for this engine; then I d pull off the rear box and massaged a bit but still did not fitted so I pull off the other
-After that, I screw out the torque stay studs and cutted 5/16 of em until they cleared the frame. Put again the boxes but not fully torque the screws and nuts.

---I modified the rear frame so the oil tank do not fit anymore. Im transforming it or at least trying but Im not sure about it
Possibly I ll make a custom one instead of this modified original

-I have photos but a virus entered the camera SD card in the cibercafe..and not my photos and camera...I do not want to try today at least..
---what about this thing, that by the way seems that nobody follow this approach (may be do not work...?):

-think on the OIF.
Im thinking to make an oil tank, a vertical one with the OIF filter and sump plate in the bottom, like the OIF middle bone tube..
good idea or bad?

what s your opinions?

thanks

Hey Reverb, glad you got your engine in, in the end.

I think the vertical oil tank will look just fine. Take a look at mine, you could do similar but with a flat bottom.

Sorry to hear about your technical problems, hoping to see some pics soon.

Cheers Dan.

-Hello Danboy, yep the vertical oil tank but with the OIF filter and sump plate is the idea I m talking..but not sure if will work.

Hey Xlh1958, in most of the comments I tried to put some problems that I found, so possibly you can check all of them.

-here some pictures of the "smallering" of the original oil tank to fit

...hello,
after all that work on the oil tank I see that I do not have anything to put in the other side of the bike so do not look so good
In the meantime a friend found a big filter and I ll try to make the vertical tank with that. so as it s cylindrical, will looks better than the other if I do not put other stuff in the left side of the bike.

But I m asking this again, because seems that nobody did similar thing and I m not sure if will work or become a hassle...and Im in the middle of the situation:

-I m thinking to put the OIF filter and sump plate on the BOTTOM of the vertical tank.
You know, so NO external filter will be required.

I m not sure what to do (if I put the OIF stuff) with the lines that go under the original tank. If I do that, should I go with the OIF oil scheme?

-Will be no good due to vibrations and leaks oil?
-Better to have an external filter to provide cool to the oil?

I really need opinions on that.

...hello guys, still do not have the PC but here some pictures.
Making the footrest; you see that they do not go onto the engine mounts. In this way seems easier to fabricate (all in one piece) and do not pass over the covers; also, I do not have the motor mounts...
I know that in the 66 models or the 64 Bonnies I cannot recall right now, have these pegs grabbed to the frame
then changed, so possibly a bad idea?
I listen opinions about that.

...hello,
so I have this slim line tank (2 1/2 gallons). I found this in USA via Ebay. In my country there are only 2 with this one. I bought it about 2 or 3 years ago very cheap, with 3 big dents and rust inside but not on the outer side; Very difficult to locate one, also normally they are between 300-800 D !
The rust outside appeared due to a guy sanded the paint thinking that I leave the tank there for new paint work.

-I d get rid of the big dents with a rod (inside the tank) and then hit firmly with a hammer.
-I do not have the tumble dry option so I put a thing similar to a chain and proceed to shake and swing the fucker until tired, then again and again trying to eliminate the crusted stuff.
The Vinegar is not cheap here due to not sell it in gallons only small bottles. Also I let a pair of very rusted exhaust holders for 5 days submerged in vinegar and not very impressed with the results; yes, it take off some rust but not too much. So I decided to put Coca cola inside for a few days to see what happens. I know that is mild than the vinegar, but cheap too.
I let the coke 10 days but not too much happened.
Clean and put 250cc of hydrochloric acid and top with water for about 2 days. Then flushed with water and baking soda (100grs)
After that I went to the hardware store and bought a liquid that the main component is phosphoric acid that comes to get rid of oxide
After 5 seconds!! the inside of the tank came kind of Grey without the oxide. Not so incredible in the outer part of the tank anyway...
Flushed with water and dry with hair drier.
Then I put some oil inside and shaken a bit to prevent forward rust; however, after few days of bad weather the rust seems that just starting again...
May be better put gasoline inside?


--I just found this rod and checking possible handle bar. I want to go with something like drag bar, but possibly to low due to the future seat.

Here s some photos with different angles.
what do you think?:

i really like your project reverb, keep it coming!

how did the tappet blocks work out? i saw no one post about if it's okay to use two of the same blocks on your cylinder.

i have the same problem, but opposite. i have two intake blocks and no exhaust block....damn eBay!

...thanks every one for the interest and Xlh1958, A65, T120R and Vintagespeed for comment.

-Still do not fire up the engine so I really do not know if that block will work or not; I think will work, possibly a problem could be some oil smear outside the motor...

In your case is different (depends on the year of the engine) because the important block is the one with the oil passage

i found vinegar to clean out to perfection the tank I've just fitted to my Yamaha daily ride.

But I also did flush it out, rinse, and then fill with water and put maybe 5 big spoons of baking soda, (just to be sure, it's cheap anyway) and let it sit for 1 day or so.

I then emptied it out, dried it, and filled it with fuel and rust hasn't returned at all since (1 month ago)

your build is cool by the way

...been a while, not too much is going on, I do not have enough time to dedicate it. I have the project in another town, so is a pain in the arse to find the time to do it and spend all day there, eat bad, very cold road when returning home, etc.

-applied putty to the tank; looks like lots but is super thin, like 0.5mm. The putty that s in the coil holes is the one that came with the tank, I do not know if original they had it...

I saw that the rust keeps coming so I sanded a bit more then airbrushed a bit of primer to see the little imperfections
This is my second fuel tank work, the other was 15 years ago or so.
A buddy who s a pro painter offered me to prep and paint it but I ll try to do it myself.

Sir I have to hand it to you to keep moving forward with the difficulties as to parts supply. Sometimes it is forgotten as to how easy things can be here in the U.S. as to parts availability and looking at the vendors we have here who have came across these difficulties then building the pieces to streamline the building process. Myself, I will keep checking in to see how your bike will process.
If you ever get to Alaska I would like to buy you a beer. Or several.

...hello 4444, thanks, I ll try.

-Hello Snodawg, yes, many difficulties, but I try to keep the moral high.
Im thousands of kilometers from Alaska, but you know lots riding all the Americas by bike...at least in newer bikes.
A buddy here will take the road right there to Alaska in a 4 months road trip, but in new bike. The trip will be in 2015.

-Hello Danboy, yes, I really like these slim ones from the factory.
I want that this bike be a Triumph; I mean, the gas tank is one of the things that distinguish a Triumph among the others.

-Hi Boxxman, took me several years to have a feel for the swing arms; still I like more the rigid look and ride it daily on my other Triumph

Tell your friend to try and time it so he shows up in June or early July that is when Normally our weather is the best. If he waits till mid August that is when the rain starts.

I did exactly that in the custom oil tank I built for my Triumph. Works absolutely great.

But I m asking this again, because seems that nobody did similar thing and I m not sure if will work or become a hassle...and Im in the middle of the situation:

-I m thinking to put the OIF filter and sump plate on the BOTTOM of the vertical tank.
You know, so NO external filter will be required.

I m not sure what to do (if I put the OIF stuff) with the lines that go under the original tank. If I do that, should I go with the OIF oil scheme?

-Will be no good due to vibrations and leaks oil?
-Better to have an external filter to provide cool to the oil?

I really need opinions on that.

...ok, after all the turmoil, possibly is good to have more than one build thread rolling; also, not much going on with the Triumph guys lately...

Blacknight1 did not showed so I decided to not use the original oil tank, that as you see in previous pictures, I tried to cut to small down a bit, but with the rear frame changes just do not feel properly.
I m using an oil filter from a big machine, the ones that use to make the roads, to make the oil tank, they are round and big but not enough to hold plenty of oil and a bit of empty space for the lines, air; so an stripe was added.
Now is no more rounded but still have some kind of shape...
I m using the internal stuff and all the threads from the original tank, I think that is a very good thing.
Here some photos:

...hey PanheadPete; you are right, I did not thought that way...but you are right.
I was thinking to use the internal parts etc to go a "proved way" with the tank stuff.

-Here some pictures of the tank mock up; still I need to put the brackets to the frame.
Cut it the oil pipe then change the curvature to fit the new length.
Cut it the bottom tin and added the feed and the drain holes; also a hole for the return pipe.

I want the filler bung on the outside of the frame. I fitted the breather inside the frame under the seat.

-I want to put around 3 litres (something like the late 60s stock) but then I m concerned with the length of these vertical tanks regarding the oil pump. You know, may be too much low level for the oil..??? possibly I just cut 1 1/2 inch from the bottom to have less problems???

What s your opinion about that?

Xlh1958, Danboy and el Diablo, thanks.

Yes, the tank fits well, but still very concerned about the bottom of the tank regarding the oil pump...
I noticed that all the non OIF Triumph s have the bottom edge of the oil tank in the same horizontal line of the DS top edge; that goes for a natural and "direct" way for the oil (and gravity)
Cutting 1 1/2 inch from the bottom, will transform the tank in a not so "stylized" figure but may be help with the gravity effect...or may be not??

-Also, the only place to pass the oil tubes is from under the swing arm.

-May be all that is not so good with the "power" that the oil arrives to the pump??

I really appreciate your insights about these plumbing

Thanks

...thanks Drainsurgeon and SG.

-in the meantime I just trying to deal with the engine mounts. You know, it s a T120 frame and a late T140 engine, so the gbox lever is in the other side. I do not have any rear mounts, so I used a piece of iron that a friend gave me, very difficult from the beginning, but know are nearly finished; I need to clean more a bit by hand, etc.
Here s some pictures:

...hello Drainsurgeon, well is not a milling machine or a CNC one, so no perfection there, but I do not have other option; very rough finish, but will be right before paint.

Hello Ourmaninshanghai, I think it s the way to go if you do not want to spend a small fortune in every step outsourcing all the work.
I m not cheap, I put around 10 000 Dollars in this project...


Here photos from a lever, etc that I m trying to design to operate the rear brake by cable:

...Crawler07; well, I ll try; thanks.

-couple of months passed and I had not time to go to the town that I have the project to continue with the build. Yesterday, with some help, I did some things.
May be some of you still interested, so I decided to take some photos.

-I had a problem with the swing arm, due to the welding, so I was in need to make some clearance between the arms.
Then I saw that the down tube of the rear frame had some kind of tweak in the middle.

...by the way, may be any of you have opinions about to reinforce the swing arm. I mean, I stretched it about 2"...
Regarding taking curves on the road, etc.
Also, it have 2 thick washers in each side but place for only one(¿?). How s that?
´67 frame.

love this project! might add larger gussets top & bottom of the swingarm to strengthen it and fill in the front before the tire.

...hello, Vintagespeed,
yes, but I do not know if should I go with flat ones, top and bottom like you say or make others like the originals and welded in the same way (inside) not top and bottom...

Also, I read somewhere that the swing arms should have some lateral flex...is that right?
so, if that s correct what s would be the right length or thickness (if its flat) for those gussets?

I checked some pictures of guys who in the past stretched the s arms but I could not see if they made gussets or some kind of inserts to strengthen its

thanks

Hello Ourmaninshanghai, time ago I read that page but I forget about it; thanks to reminds me and I ll weld something similar but smaller.

-Now I have a big problem with the rear frame that I do not know how to fix it.
I do not have a photo right now, but the thing is that I have the rear wheel aligned regarding main loop and sprocket, however, the right side is too close from the shock; so the wheel is not equidistant to the sides (to the shocks)
I have checked the frame but the down tubes do not look twisted anymore.
It s around 5/8" more closer to the right side (but the wheel remains aligned)
I do not how to fix it at this point and this thing do not let me to continue further.
Its not a problem for the spindle spacers, etc; the problem is in the rear frame itself.
That 5/8 is on top, where the downtubes meet the side tubes in the mount for the top eyebolt of the shocks.
I do not know why the frame is in that condition, because you look at it and seems straight.
Also I was thinking in different ways to bring it (push it) to the other side to achieve symmetry but all are kind of butchering stuff...
I m a bit frustrated with the frame thingy, many hours wasted and still plenty of problems.

Hope some of you can put a bit of light on this subject or may be know that these things were somewhat normal in the past...

Thanks in advance.

...well, long time, I managed to make those kms to the garage where I have the bike; here s an update Drumrooster and to the other guys that are interested.

So finally I massaged all the rear frame, heated the tubes, heated the swinging arm again and finished with an acceptable symmetry. Also pulled out (by heating the weld not by cut) the top rear part, that by the way was an add for the previous owner.
However, there s no room for the chain...the sprocket is centered straight with the rear sprocket . The chain will be in contact with the wheel and that s plain crap. I just have about 1/8 to that side on the hub, but seems not enough with a 130/90.

-I designed this spacer that act as dust cover too and have the same style that what I did for the front hub. I ll chrome it like the other.
Here some photos:
EDIT to fix the photo problem

Some of your pics say "moved or deleted". I was never good at reading comprehension...can you adjust the spokes on one side to move it over. Also, I extended the swingarm on my TR6 about 1 1/2" and it handles really nice on windy roads and is for fun for fishtails in the dirt.

...both sprockets are aligned and the middle of the wheel is aligned to the center of the main loop...
so if I move the hub more will I have a not so straight chain?

-I extended this about 2"; I ll see how handle it..

I dunno what happened with the photos, I put em again

...Bobbydeville, thanks for your kind words; I guess, is because I post all the problems that I have been found on building from scratch and trying to sort them out someway or another.

- it was raining so I decided to let the Triumph in the bike port and grab the vespa style scooter and ride those 25 kms to where I have the project. Not so incredible to drive under bad weather (there s too many arseholes in the road+ low visibility) but a friend was going to be there to help me a bit with the rear frame so I just went.

-I m not very happy with the wideness of the frame there, so these photos are kind of a mock up of that tail not really welded.
The small fender goes ON the frame, so cover it, hence will be too wide in my opinion. Like have too much light between the tire and the side of the fender. So the wheel will looks like a thinner thing losing "visual power". Will be different if the tire is just thin.
The frame on the shocks part have around 10 inches wide.
In my rigid Triumph I did an 8 inch fender that can hold another guy seated there. I need to weld that tube there with a strut inside of course, due to have a tail that can hold and support a person...so I do not know how to thinned out a bit that tail.
The other thing, but I dunno about the look, is make a fender strut similar to the sportsters ones.
It s very difficult to visualize all these from scratch.
I accept suggestions.

G'day there Reverb, 130 tyre is too big, 120 will work as far as chain is concerned.
I had to go back to find out how ya welded the swingarm, I was a bit concerned, I extended mine by re fabbing the fork that holds the axle 'longer', but I only went 1 1/2".
Mate, I'm not trying to be a smart arse but get rid of the paint and rust with a flapdisc before you weld oil tank,and chamfer the pipe joints so you have a 'vee' for weld to fill and fully penetrate so when you grind it back flat....well you get the picture?

Hey the bike sits nice, the work is authentic and classy, keep rollin man!!

...hello Daddyboy, sorry for the delay with the response; I have a 120/80/16 low profile on the 500 rigid and looks somewhat lost on the bike and more with the swinging arm.
I see that lot of people use the 130s...
Regarding the extension, I went around 2 inches, so not too far from you; and looks strong; I used a solid rod and butted both sides then did couple of holes to penetrate with the Bronze...hope all it s strong.
I do not see the problem in the oil tank that you describe; please put more light on it.
But I have the tank welded and do not have leaks...

-hello Dash47331, thanks man.

I just trying to figure out the tail however I do not like it, too wide.

...hello, for now I decided to get rid of the cable idea for the brakes and did this thing.
I have little space regarding chain clearance (by side)
I do not have good photos but I welded couple of bushes on the motor mounts where the rod pivots when you push the brake pedal, then an L shaped thing where the brake rod is attached.

...have a few bits done; all in rough state:
-top torque stays in a simple way; just heated a piece of metal
and bend it then cut and did holes.
-choke clamp the same way.
-the exhaust pipes adaptors
The pipes are 1 1/2 as we discussed in other thread. I went to a shop to did them; I forgot the camrera, I put the bike on a truck to go there, so I
was a bit worried about scratches, etc; well we took a rod cutted in 3 pieces to mimic the pipes then spots welding and couple of
inserts (pipes) that provide a "pivot" point to have the top curve of the jig for one side or to the other; very practical; I must say.
Then he used his machine to does 2 small curves on the pipes and that s it.
I have the pipes parallel to the floor and in the same line of the frame front tube; still uncut and too long, also I think they are too far from the bike; I ll try to
tweak them a bit more; may be I weld there kind of trumpet tips

-I moved a bit the master cylinder to have place for the regulator, but still the tank rubs against it, so Im thinking to cut 3/16 of
the fins...
That s a good place; its hide, have plenty of air, in front of the engine not on top, so no heat involved; no rain; this regulator
have very thick cables so better to hide them there.

Here some photos:

...ok, I decided to do an update for the members here that followed this thread; I came back from Japan, 2 months trip, I thought to finish the bike promptly, but when arrived I found my house stolen, the fuckers broke down the backyard door!..so not only stole many important things but they also took couple of parts of this bike that I have in a box. So Im in a very bad mood; I ll try to update this thread with a better pace but I need a well disposed mood and order again some parts.
Will continue with the protocol that I m using right now, so next week or so I ll go to the town where I have the project and do something; I ll post some photos.

So the odyssey continue, thanks for the patience.


---edit: also always forget about it, I know that the title is misspelled but I do not know how to change it.

if you need an ex block pm me. as for the two ex , they will work as the ex was the only oiled one used, but i think that they are dif diameters on some years. i think your doing exceptional work and very creative with this project. if the blocks fit , n thats what u have well use them , but only remember the oil passage . that bike is looking very sharp indeed.

friend , you are one determined and talented person, i really like the oil tank , you could have the bottom feed even with the bottom of the motor as the oif tanks were. i think it would make little difference. those mounts are beautiful! keep on with the creativity.

...thank you very much Drumrooster, Brent64 and Ourmaninshanghai.

-regarding the bike, I found the pipes too large to the front passing the frame front downtube, also too large to the floor, so I cut them in 2 places (on top and in the down tube) , however, I noticed this after the welding...so I re did it again. The adaptors are made again due to I finished with a not so big I.D.; now have the same diameter than the valves.
Had to make another piece to weld in the pipes to fit. And an inside mini tube to hold the pipes in place and have the right curves down there.

I have a question regarding welding:
I used Bronze, is this ok? or cannot handle the heat, fire, etc?
Tomorrow I ll use Bronze to weld those cuts on the pipes...but I have different opinions here about if it s good or bad if its resist or do not.

I hope some welder here put me in the right direction.
Thanks

Here some pictures.

Hey Reverb, I am sorry to hear your bad news. Some people are the shits and breaking in is pretty low.

Bike looks great though, I like that you are getting on with the exhaust.

Keep to pics coming.

Cheers Dan.

...hello Danboy, thanks man.

-In the meantime, I have the lever done, in rough state due to I need to check few more times the way I can place it.
Im thinking to place it under, like in the photo, but parallel to the shock.
In this way Im not putting an obstacle in front of the chain adjuster; but I dunno if it s work already.
-I used a Matchless gear lever.

Ive seen bronze used to mate siameze pipes lower down but Im skeptical about bronze that close mate.
The plug joining the pipes will disturb exhaust gas flow if yr concerned about performance.
Like the choke position.

...hello 4444design, thanks man; I ll try to be more motivated to drive those 30kms (60kms) to the other town where I m making this project.

Hello Daddyboy, I see what you say, I cut off again and get rid of the joining plug (however, is too small and thin to make any difference...)

Here some pictures of the handlebar that Im making:

-1" in the middle then 7/8 to put the levers and grips.
-Lathe work to fit one inside the other.
I tried with the press but did not worked properly so the heat was the rudimentary solution; you know, I do not have the right tools to work with metal so Im trying my best to do a clean work without the gear.

...hello, many problems that Im trying to solve:
Rear brake; the foot lever did not had space to perform right without touching the exhaust pipe, so I relocated in the middle of the motor mount, cover the hole, then did a spacer; however, now, the thing do not looks so clean like before...(all that previous work to make them nice was useless)
I relocated the hollow piece that I did for the other mount, both now are aligned straight (not like you see in the photo couple of post before) to clear the chain, so I straightened the rod by heating it. Red hot heated the lever to get a bit more curve.

Ok, now the next big problem, the kick lever...it did not have space due to the spacer for the brake lever...man...so I measured triple time and did the spacer and Bronze washer to just clear the pipe (I ll manage to put the pipes in the only place that I have now)
and finally kicker will work but with only 2mm of light...
I was thinking to make an acorn nut (stainless) but now I do not have enough space.

Alright, but the brake did not brake actually! I tried welding that flat bar that pull the brake rod in different positions to achieve the desired effect but without luck; also I tried with different lengths.
I do not have space too; finally, the only solution was "the Donkey kick", so now the brake rod do not pull (that s the best way) but push!, so I changed the other rod, spring and I made one 8mm thick and double nuts. Tweaked the brake spring too.

-I did the torque stay too, with an stainless tube. Those moldings were done like the old brits with 2 flat bars and a vise.
Then made the brake nuts etc all in stainless, but still without polishing.
In fact are all in rough state.

-Now the LINES do not look so clean; as many of you know, I say when a bike do not have pleasant fluid lines, etc
Im saying this, cause now I finished with a 4 different lines: the swing arm, the torque stay, the brake rod and the left exhaust pipe.
I preferred the older torque stay system like the one I have in my 500 pre unit that is hidden on the frame; these other bars are truly ugly and longgg.

Anyway, here some photos:

Great thread with lots of nice fab and mechanical work going on.
Hand shaped parts are just in a class of their own.

Great job!

...hello Lester, thanks; I tried to build a simple bike but she s very rebel, I must say.

-I let the pipes to weld by a guy who have a TIG or by defect to weld with oxy acetylene...he said yes; I let its in his shop due to that will be the best welding for those cuts (check previous photos)
But the guy did the job with electrodes then finished sanding with a grinder so now I have a not smooth surfaces and uneven not straight line in that area (do not appreciate so well in the photos but the dents are there)
Im thinking in refill them, by I do not know a good method; then smooth out everything by hand.

-I found a place to hold the pipes and place the bracket.
-Cut the foot pegs, red hotted and tweaking a bit; still unfinished.
-Made the rocker top torque stays distance pieces and thick washers with stainless steel.

...a have problems with the sign in, posting, etc so days trying to upload some photos; anyway, here some of the side kick stand. Main problem is I do not have too much space or ground clearance so the bike finished too tilted; like 45º; seems that I do not have other option; but if you want to suggest other possibilities; will be good.

...I almost finished with the pipes; these fuckers took me forever...still I need to make kind of rings for the tips and may be a Triumph logo. I m happy that I get rid of the dents (check previous post) and now have "fluid lines" that follow the contrast with light and shadows in the downtubes.
I did the trumpets with old silencers and to see if I can put a bass note in the final sound; I ll see.

Bit a pain in the arse to keep the things somewhat symmetric.
Of course I need to weld everything and get rid of some dents.

Hello, very busy these two months to continue, only 4 times I went to work on the bike; however, I just resolved several issues that I had not so clear, like fender;reinforcements; seat, etc.
I have been building this fender from near scratch; I used an old leftover as a base and built from that.
Made it like a puzzle due to several things going on. The main idea is to hide the side brackets. These struts will hold the fender (and let a person sit there) and the detachable sissy bar. Still not welded the bungs that will serve to screw the bar.
I did these side brackets first straight then a bit bended over; finally, I bended similar to an sportster (I did not took photos about it)

-the camera is not good so there s an optic illusion about the distance from the tire. The lens show the fender too far back and too tall regarding wheel, but in reality the position looks better. The back tip of the fender finish in the same line of the rim.
--Of course all in rough state.

---you know, is so simple the fender and seat solutions if the bike will have only one seat or the fender do not need to carry a possible passenger...like 90% of the bobbers here.

Thanks for keeping the interest.

...Hi Daddy boy, yeah freestyle because I did not had too many options but still tweaking here and there to try to finish it.

Here I did a shield for the oil tank; most secondary roads do not have asphalt here so a bit of prevention to the tank paint, due to I do not have enough space to continue the fender with the right circumference.

-A tube to reinforce the upper part of the rear frame.
I ll reinforce the swing arm too, however, I do not see it stiff enough...I accept opinions about it. May be I m accustomed to the rigid frames?

Good move bro, triangulation equals strength.

Swing arm; I made a new axle plate and butt welded for 1 1/4" stretch.
Plugging pipe? Entirely up to you man. I would want to be confident of my welding skills.

Check this out Reverb.

Actually after looking at your arse end again (yeah righteo), The more you strengthen the top. ie: what you are doing to triangulate the frame. If you mount that nice rigid guard well it will put less stress on the swing arm IMO.
Imagine what that SA is doing through a speedy bend and you hit a pothole with your top frame un strengthened.

...hello, may be some of you still are interested in this thread.
Long time without updating due to: working overtime; 2 broken cameras!(infamous lens error message); I have been having extra working updating my house; you named it: electricity lines; new flooring, stone wall covering, etc; my other motorcycle had a problem so I just dismantled top end, primary etc to keep riding..
Regarding the bike, I made again several things, like the exhaust, so not to much to update.
However, an important part is that I really do not have the tools (or a skilled buddy) to finish with the rear part (mudguard that can carry a pillion + detachable small sissy bar with hidden tabs etc)
and I was and still not satisfied with the trial results.
Now I am at an stage than I do not know how to go forward (mainly for not having access to the right tools); ok, mostly I did it without the right tools but now I have tight spaces and are the finished parts so all should be correct...
Anyway, here photos toying with a modified breadbin tank and the last iteration of the exhaust (I chopped couple of new ones and made a "lip" for the cone)

...hello,
I finished with that mudguard; is not good but I want to finish with the bike and then if I have better tooling options, etc I ll do it again, these not so perfect parts.
The mudguard has side brackets inside where I welded 3 threaded tubes per side to hold this detachable sissy bar.
When the bar is not on the bike you do not see any of these other parts, and still the fender can hold a person.

Of course is not the best to have fasteners down side but we ll see what happens. The screws are (6) 3/8 UNF thread.
As mentioned this sissy bar is detachable so I ll only use it when a big bag would be used.
The tip of the rake follows the frame rear down tube and the forks.
The rod is 9/16 mild steel.
I think there are no so many of these sissy bars for the swinging arm bikes.

...I let that mudguard to a guy that have a TIG with the hope that with that tool and his knowledge, better than mine, performed a job that did not "moved" the tin to one side or to the other...did not happened, and Im finished with an even crappier guard.
To try to put again the thing in shape, I had to use an small jack. I do not know if in the future after couple of Suns, the fucker could shrink again...¿?

-I bought this horn from a JJ member, but did not worked; so I decided to open it and after a bit of sanding, cleaning and a dash of oil, it s perform superb.

Let these pictures, for the guys that have horns that they think are death; still you can get good life from those!

I agree on the tail light! It would seem to me the vibration from the swing arm alone would be enough to kill the tail light.

BTW, is there any baffling inside those mufflers? It would be interesting to hear them, they look nice! You have the stance just right. I like where you are going here.

...hello, yes, also the vibration just killed me the license plate on my 500cc, also I lose it riding in a long trip in other country, due to freeway speed, so I made this one stronger.

-no mufflers...yet. I ll try this way but if the sound is too annoying I ll put something. I see that the 750ccs do not sound to cool as the others without the silencers..

Thanks

...Lester, thanks; it s a slow building due to I do not have the right tools and the right knowledge sometimes.

Here the nuts for the rear spindle; two for the drum brake lever, for the torque stay and the other is for the brake lever.
SS; not so perfect but would play...

...the other day I worked on the brake action. After tried with a rod then thought about mini master cylinders, slaves pistons ratios etc I m trying this cable thingy; is not the coolest stuff but may be it can work in an easy way...
Is based loosely in Nortons brake.
All is SS; of course the nuts are not those; only for the mock up.

What effect will the movement of the swing arm have on the cable? Any?
Logic dictates that since the wheel and the swing arm move in unison all will be good, but sometimes the real world surprises us....I really like the fab work.

...hello Mike; well, hope that do not have any but this is trail and error...
The "fork" there seems to help with that.
Still not sure if it really brakes.
Will be another spring in the brake plate, similar to the stock one.

...hello; the other day I made the seat pan; is for the me and a possible passenger.
Still I do not know how to hold to the frame; mainly the rear part. Well, I would not put anything there if not I lose the lines so Im thinking to put any kind of grab where the "flat" part meets that fender cover part.
Im open to ideas if you want to throw away them.

Here s some pictures:
Thanks

Regarding the rear brake...

Here are some photos of the right brake conversion on the '65. I've taken them in series from "big picture" to details. The last one is blurry, but is really there just to show the location of the brake pedal on the right. The picture from underneath showing the brake pedal spindle (shaft) following just under the front of the swing arm is VERY similar to some of the pictures you've posted and shows the curved lever discussed below.

I think you're on the right track with the brake lever welded to the brake pedal spindle set up, and as you can see in the pictures, it looks like the key to this is a curved or angled lever pointing up rather than down and uses the standard brake rod (or something close to it). It looks like the lever is curved to clear the swing arm bolt but it actually moves in between the bolt and the engine mount plate. This set up will require the lever on the drum to point up in stead of down too (as the stock setup is). The clearance is very tight, but you may be able to pull it off (sorry I don't know how your late model engine mates geometrically with your older frame), but it looks like you have about as much clearance as I do between the swing arm bolt and the left rear engine mount plate (practically nothing!). If your swing arm bolt is closer to the plate than mine is and you have no clearance at all, then maybe you can fabricate a lever with more of a curve to clear the bolt?

As far as the curved brake lever throw is concerned, with the brake rod adjusted properly to the brake drum lever, it only moves forward about 1/2 to 3/4 of an inch when the brake pedal is fully depressed. Didn't actually measure it, but probably closer to 1/2". Not much movement at all!

Hope this helps!!

Always wanted to try this, never did because it looked too complicated. Looking at these pictures it's more simple than I expected.

...hello 70bonnie, thank you for your time. It really helps to have a person who actually use that system.
Do not get it two things:
1- how that piece between the swingarm and the engine mount plate is hold.
2-what type of movement does there? up I think; so did you made a bush or bearing to pivot it?
