You asked for it, lets see if I can remember it all. Its not a Rickman seat but a Universal Duck Tail seat from Racecrafters circa 1978. I started by cutting off the frame above the f/r motormounts and threw away 27lbs of cast crap and replaced with 9lbs of chromoly. I bought the last set of snowflake magnesium wheels (8lbs each) sold by Kimtab when they went bankrupt in 76. Ceriani roadrace forks with late model Hawg Halter 4 piston calipers (dual front, single rear with 12" rotors) modified for my bike, Sputhe twin carb XR style aluminum heads (extremely rare) on top of Drag Specialties 63" aluminum cylinders. Sifton cams, C grind, XR pattern on early XL shafts. Mikuni butterfly carbs (prototypes Mikuni gave me in 77). Hand made exhaust(supertrapp mufflers), oil tank, rearsets. Kickstart delete (bump start),generator delete (battery behind seat, total loss system) Tomaselli clip-ons. Magneto mounted in generator hole ala XR750. Bike weighs in at 360lb/lbs dry. If I forgot anything ask and i'll tell you. I havent raced it in 35 years but after attending the Vintage Fall Festival and Swap Meet at Barber Motorsports Park last year I plan on running it there this year. I tell people when you get on this beast you will choose between 2 things , hospital or jail. I have been racing cars for the last 20 years. This is getting ready to be torn down again to powder coat the whole thing for display in my Powder Coating business. (www.CreativeCandy.org)

Good looking bike!

What is that rod that looks like it is attached to the left headlight bracket?

This bike is amazing. I've never seen Sputhe heads like that before. Too bad they're so rare. The world needs more dual carb Sportsters.

This was a set that he made before offering heads and cylinder packages making the iron head 1200cc. Mine is one of maybe 10 sets in the world and I have located 7 of them including mine.

I still get extremely pissed when ever anyone mentions fairing. I used to have an acrylic 1 piece 1/4 fairing that was smoked clear. It fit the bike perfectly size wise. Through out the years it somehow got legs and walked. I cannot find a replacement and all the other 1/4 fairings are just too big for this skinny bike.

AWESOME !
Barber Vintage Fest is run by AHRMA. You might want to get a good look at their rulebook . I'm not sure there is a class for your bike without some mods.
WERA also races at Barber as well as all over SE and they have class structure that is easier to fit into.

2/5-6 Talladega Gran Prix Raceway, Talladega, AL-cc,H,rs,

3/18-20 Roebling Road Raceway, Faulkville, GA-H,HL,N,

4/16-17 Nashville Superspeedway, Nashville, TN-H,rs,

5/7-8 Barber Motorsports Park, Birmingham, AL-H,HL,rs,

5/21-22 Jennings GP, Jennings, FL-H,HL,rs,

6/4-5 Roebling Road Raceway, Faulkville, GA-H,HL,rs,

6/11-12 Talladega Gran Prix Raceway, Talladega, AL-cc,H,rs,

6/24-26 Road Atlanta, Braselton, GA-H,rs,

7/23-24 Roebling Road Raceway, Faulkville, GA-H,rs,

8/4-7 WERA Cycle Jam at VIR, Alton, VA-H,HL,

8/20-21 Talladega Gran Prix Raceway, Talladega, AL-cc,H,HL,rs,

9/9-11 Barber Motorsports Park, Leeds, AL-H,N

Nice piece but definitely doesn't fit any of the AHRMA classes.
You could run with WERA in V5 - if it was 1000cc or under it could run in V4.
Pretty vicious competition in V5
(from the WERA rule book)
Vintage 5
Pre 1983 2-stroke factory road racers up to 500cc.
Pre 1983 Production based 2-stroke up to 750cc.
Pre 1983 4-stroke push rod unlimited displacement.
Pre 1983 OHC Twins to 1200cc.
Pre 1983 OHC 2 valves per cylinder to 1200cc.
Pre 1983 OHC 4 valves per cylinder to 1025cc.
Among the eligible V5 machines are the following: Ducati F1A and F1B, 750cc limit; Honda CB750F, CBX, CB900F, pre-1986 Honda VF500, VF700, and VF750; Kawasaki KZ750, KZ1000, Z1, GPZ 550/750/1100, and EX500 without restrictions and regardless of year; Suzuki GS1000, Seeley Suzuki 750, pre-1986 Suzuki GS 750 (no hybrids, i.e., Suzuki GS 1000 motor in a 1985 mono-shock frame), GS 500 (no restrictions); Yamaha FZ600, Seca 550, Seca 750, Virago 980, TZ 750. RZ 350 with maximum displacement of 450cc.

V5 shouldn't be a problem as its mostly GS500, EX500 and occasional RZ350s that show up for that class. Couple of big bore 4s that bump up from V4. That bike will fit in well.
The bump up into V6 should me more interesting .....
It will also run Clubman.

I love that you're going to run that beauty the way it was intended instead of locking it away. Very cool.

Could you please post some videos of it?

I'd love to hear it run and see how it gets around the track.

Thanks and good luck.

New plans at this point. I missed Oct Barber meet if thats when it was because I was crew chief on a C Gas Competition Coupe 59 Nash Metropolitan that we built to take to Bonneville which we did in aug. and broke a 14 year old record at 261.929mph. We went back in Oct to run World Finals and ended up getting rained out. But my buddy offered me his XR750TT fairing and I am changing the tank to a Dunstall road race tank and taking it to Bonneville next Aug. where we will break our record in C/GCC with the Metro, try for a new land speed record in Modified Sporstman with a Miata we are building and make some runs with my bike in the down time between runs.
Heres the Metro that got me hooked on Salt:

And the record time slips:

Kirk Kelly of Sporty Parts (the old Sporty Specialties) is sourcing these covers,
the one posted above with the motor shaft access is the thinner 5 plate XR750 model so be aware, I think they also make them wider for an XL Ironhead as well...

Glad I found this thread. I've been trying to figure out a way to use an external electric starter for starting my bike that has no starter on it other than a bump start. Enfields electric start cover is a bit pricey but does exactly what I need.

Can't you use a little B&S motor with a small utility wheel attached and hold it next to the rear wheel like the XR racers use?

Can you find a link to a pic of this set up? I have seen the roller starters you put under the wheels of a vehicle. I am looking for something that will start the bike while it's on a stand or on the grid at Bonneville or Ohio.

New Legendary Motorcycles Dunstall road race tank. Fits the style much better than the old tank.

Thanks, but No Thanks. $1050 for a gas tank, Fuck him. He's too fucking proud of his stuff. He makes stuff for the doctor/lawyer wanna be bikers that don't know a wrench from a screwdriver and just want to impress their friends with how much money they can spend.

I was surprised to find Legendary Motorcycles and Aerotech actually have fairly reasonable prices for tanks and fairings.
I will be running a slightly modified XRTT fairing for Bonneville and Ohio and then an Aerotech fairing for the street.

My tank was custom made for me by Legendary Motorcycles and has a special sealer for running todays gasolines. This tank is only $440 with the aircraft gas cap or $360 without the cap.

Here's where you'll find my present cover at:
http://www.sportyspecialties.com/new_products.html

I just had the best Friday the 13th I could have wished for. I found a local motorcycle shop that had a dyno and went to talk to them about dynoing my bike and talk to them about a sponsor collaboration. After talking with Wilson Cadle of "Doc Slicks Twin Service and Repair" for a couple of hours I knew I had finally reached the right guy to handle what is left to be done on my cafe racer to ready it for the Sept. event with the ECTA where I know believe I can bring home not 3 but 4 world records. This guy shares my passion and was in awe of my vintage piece. We agreed he would do all the labor and get it running and dyno tuned if I pay for the whatever parts are needed. We picked each others brains for a awhile and I know we were both asking questions to see if the other was knowledgeable on the subject as the other. He asked some sneaky questions that I had the right answers to which I think helped him decide that I knew what I was doing and my claims were obtainable through not only my past accomplishments but what my future expectations are.. I knew we had a deal when I asked him if we were loading the bike back onto my truck or was I leaving it here. He said " you're leaving it here". We shook hands and both left with a list of things each of us need to do. I am so fired up now especially after seeing this past weekends ECTA results posted and saw that still no one has entered a bike in my class. We have 2-1/2 months to complete preparations for another dream on my bucket list.

01,
Note that the Enfield Cover is not the same animal, as the Imperial, also the enfield I believe is made for a thiner basket such as the XR, they may also made them for Sportsters as well.

I assume the "Imperial" is the ribbed cover I have on mine now? I was replying to 2 differant posts, one from the guy wanting my style cover and one from the guy who posted the Enfield cover. The Enfield cover is made for the KR, XR and the XL in 2 differant widths for the differant clutch baskets.

The only article that I know of that was ever printed. I have 2 copies of that issue of CW. My heads were purchased from Alan in 1977 when they were still prototypes. He later came out with head/cylinder package for Iron head Sportsters in 1979 which is what you see on Vances bike.

Im not sure if your interested in TQ as well as HP but, let me know if you guys have any tach related issues on the dyno.
I have a bit of magneto/dyno experience.

And thanks for that other article tip. Unfortunately it concentrates on the later Sputhe head and not mine.

Chevelle, o1,
I also have a 1999 HOT XL mag (That I wish Like Hell Buzz would consider bringing back) of the EXECUTIONER Custom with Sputhe Top, chevelle this was the bike on ebay not long ago, I'll make a copy as I know you guys dig any print on Sputhe stuff.. nice bike o1, kills me that I sold my pre mo Ceriani and Kosman Wheels a few year back,
o1, yes I agree, the looks of the Imperial rocks, the guy from enfield is at many east coast swap meets, comes out with some real nice stuff, I dig the socket start.. may need that with my stroker bike some day as I get older= XLCH..lol

Nice...Alan has always made some really trick pieces...I know where there is another road race machine with a set of those heads,mounted up on a wall(the whole machine,in a collecton with about 300 other machines of all kinds),about 1.5hrs ride from here which I saw 2yrs ago...I thought about asking if it might be for sale then...seeing yours has reminded me once more to contact him to check ...;-)

We tried to buy the bucks (molds) for the Imperial cover when they went out of business in the late 70's. They wanted $25k for them which was out of reach. The Imperial is a reproduction of that cover.
All the pieces on my bike are what make it collectively so valuable. Ceriani 35mm road race forks, Kimtab Snow Flake Magnesium wheels(8lbs), Sputhe heads, Mikuni butterfly carbs, Tomaselli clip-ons. I still speak to Alan Sputhe every couple of months.

VanceBreese is from the area you speak of, I wonder if it might be his old bike. Alan had a similar bike that Cal Rayburn once road in a race that Alan later sold at auction for $180k.

The mags throw out some serious dyno interference, the tach signal will be broken up and thus the TQ curve will be effected.

I was lucky and was able to purchase just the shaft and seal plate that I will be able to just mill off 3 ribs on my Imperial and mount that setup right on to it.

I've been busy while the motor is in for disassembly and spruced up the rest by powder coating the frame and wheels and polishing up some other stuff. Added an EMGO 1/4 fairing for the street.

I love surprises and this one was huge. I called the motor guy to see how my primary cover was coming. He said it was almost ready and that he had measured everything on the motor before splitting the cases and said I had 81ci at 11:1 cr. I had always been under the understanding that my motor was only 63ci. Now I have to have the seat redone with an XR1327. I am one happy camper right now and can't wait to get this beast running.

If you go back up a few posts you will know that this bike has no starter on it at all and I am converting my Imperial primary cover to adapt the 1/2 drive hand held electric motor starter to it.

I am now reconsidering using the 79 swing arm. I can just cut 2" out of the flat sides and reweld them back and that will eleviate a longer chain and longer shocks. I would them be a direct bolt on. Right now they both weigh in at right on 10lbs each. I'll save a few ounces when I cut the 79 shorter. I think the 79 is a tad wider so I would need to make some more wheels/axle spacers.

Super sharp machine for sure. Has "Daytona" written all over it. I could see myself spending hours just staring at it. The late great Cal Rayborn would certainly approve your outstanding workmanship.

Thanks guys. Your kudos mean a lot to me. Now If I could just get Cal or the Bos Brothers or someone to make a few laps on it it would double in value. Not that I want to sell this anytime soon. Cal raced one of Alan Sputhes bikes back in the day. Alan later sold that bike at auction for $180K.

Yeah the 79 swingarm is the way to go, you might want to renforce it a little like the KC teem did to the kz1000j for the early 80-83 road race season, cuts down on flex......Roach.

I think cutting 2" out of the length will stiffen it and reduce flex. I just mounted my wheel to the 79 swingarm and find that I will need to modify an axle. My old 62 is about 1/2"-3/4 " shorter. I also believe the bearing center holes are smaller. My 62 has a welded flat sided washer/nut washer on one end and a flat sided washer and nut on the other end to keep the axlw from turning. I don't believe the 79 has the flat sides to locate and it is a bigger diameter. I will need to get a 79 axle and turn it down just past the left side axle adjuster and then make a sleeve for the right side to go into the adjuster. Isn't customizing fun?

I was thinking it might be hard to find square errr rectangular tubing that would fit snug so you could machine a block about 2 inches long that was just under the ID of the swingarm . And since you are worried about weight you could hollow it out making in effect a rectangular tube to plug your splice. I like to leave a gap (1/8th")in between the pieces I am splicing so I weld the tubes to the plug and each other at the same time. This trick also let's you grind the weld smooth without grinding all the weld away. I also drill 3/8th" holes and weld the outer piece to the inner piece around the circumference of the hole then fill the center.

I am definitely liking this idea. You could cut the factory end off ,cut the distanc you want to shorten the whole thing off, then weld the end back on . Structurally it would be stronger than factory and you would realize the total weight loss you are after

IMHO a few more inches would make it more stable in a straight line but for racing a shorter wheelbase will turn easier. Ever seen how short a Buell is. If I leave the length then I have to either cut the shock mounts off and move them forward and reweld or spend the money for a longer shocks and a longer chain. The longer shock will put them at a differant angle changing the whole engineered suspension set up. It would also change the shock mount from over the axle to 2" ahead of the axle. I think the square swingarm is stronger and flexes less which is why I want it, not to mention it is more esthetically pleasing.
Now, cutting a piece out of each arm 1-3/4" long and butt TIG welding them right back on seems like a no brainer as it is easier to just cut and weld than it would be to cut off shock mounts and reweld them and then deal with the other issues. A TIG weld done properly will be stronger than the original metal and I don't really see a need to weld a steel plug inside for added strength. I can't really move the seat as it has a shape that angles out and then back in right where the upper shock mount is. When I cut and reweld the end pieces I will decide if I want to leave them 1/2"-3/4" longer than the old stock one which shouldn't change the shock position enough to be detrimental.
Oh, and the shoes, my favorite Skechers.

Mine is at 57 so I don't really want it any longer. If anything I would tighten up the neck angle some like the Buell.

Well I went ahead and bit the bullet and cut 1-3/4" out of each arm and TIG welded the ends back on. Welded on the sliding caliper bracket mount and it is now in the oven with the Silver Vein powder finish on it. I now have a boxed swing arm that is lighter, stronger and more aesthetically pleasing than the old cast round one. And every mounting point is in the same place. I had to upgrade to 3/4" wheel bearings ($6ea.) and had to procure a new axle (Ebay-$14.75). Now all I need is to mount everything up and figure the width of my wheel spacers and the back end is done. Front end parts should be here tomorrow from the polisher. The motor parts are going out tomorrow for vapor blasting and when they come back everything will get final assembled and hopefully make some offensive noise with it.





Looks like I might lose a little tire clearance at the front of the tire:

I am going to make a suggestion, only because I fear for your safety.your statement that a tig weld is stronger than the original metal is true. However it is not the weld that I fear will fail. Because the weld and the surrounding metal do not share the same flexibility or hardness they will not ,IMO ,flex together and since the surrounding metal is not as strong, it will start to stress crack I fear,if you use it long enough and hard enough. ( it is a race bike) .
But after seeing your finished modification I have a suggestion. What if you machined billet aluminum adjuster blocks along the line of late 90's dynas? But the front of the block would extend beyond your splice. This would help keep the splice from flexing and stiffen the swingarm while keeping the weight down.
Just so you know, I am a welder / fabricator specializing in building structures that support weight many many times greater than their own, I have an older acquaintance who is a metallurgical engineer( try finding one of those in the yellow pages) who I draw on for knowledge of the properties of metal. Before going into fabricating I worked in gray iron and aluminum foundries. My point is, I know a little about metal and the manipulation of it .
If this were not a question of safety, for you and your bike I would not have reposted on this subject, and I told you about my background not to brag or brow beat you , but simply to lend credence to my suggestion. Your welds may not ever fail, but why not engineer into it the knowledge that it won't fail?
Hope I haven't offended you, if it weren't that I was concerned for your safety while racing this bike I would have kept my mouth shut.

No offense taken. I'm all about safety, it's what gotten me to 59 years old when everyone said I would never see 21. I took into consideration flexing and that is why I did the splice as close to the end as I could so it wasn't in the middle of flexing bar. The action of the swing arm has most of the force on a different plane at the axle. This bike I'm sure will not be ridden a whole lot but I do plan on racing it occasionally. What kind of "adjuster blocks" do you mean. I'm having a hard time seeing them in my mind but understand the logic you have?

o1, another option for strengthening the weld joint and more evenly distributing the forces that kcgran is worried about, would be to fish plate the welded area. A couple of 10-12 gage, elongated diamonds, welded over the the weld joint, either on the sides or the top and bottom if axle and spacer clearance is a problem.

The problem with using blocks or tubing inside of the individual legs, is that the block doesn't really do anything to eliminate stress risers, it just relocates the stress riser. The ends of the block you use inside, become the new shear point.

By using fish plates, you spread the load over a greater area and reduce the likelihood of localized fatigue and eventual failure. I've done a couple of swing arms for hill climbers and we always fish plate over the joints. Never a single failure and you certainly won't be abusing that jewel in the manner we hammered on the hill climbers.

I can give you exact measurements tomorrow ,but basically an aluminum block as tall and wide as the cross section of the inside dimension of the tubes.the block would be drilled and tapped in one end for adjuster bolts leaving enough room for a flat and lock washer and jam nut in between the back edge of the block and the adjuster plate on the back of the swing arm.now measure from the back edge of the swing arm to the back edge of the slot plus .375". Take that measurement and move forward from the back edge of the jam nut on the adjuster bolts onto the aluminum block and centered top to bottom on the block. This will be the center of your .750 "axle hole.

Now if you measured from the center of this hole ,when it is positioned in the back of the slot in the swingarm, to just in front of your splice and made the over all length of the adjuster block long enough to be beyond your splice the adjuster block would fill the void in the swing arm not allowing the splice to twist and flex.

Hope this gives you a mental picture of what the block would look like, I will try and draw something and get it to you ASAP if not. Frankly I usually can get a good idea of what the effect of force will have on a weld/ joint but in this case I am having trouble. Definitely there will be some twisting action as you lean the bike in turns, but with the shocks mounted almost directly over the axle there doesn't seem to be much linear leverage on the splices plus as you said with the splices where you put them it appears to limit the effects of leverage on them as far as force trying to separate the the top or bottom of the splice, unless the suspension ever reach its limits of travel.

Still I think this bike and you are worth the extra precaution . And thank you for listening. This has weighed heavily on my mind for a few days now.

Fear no evo has a Very Good point, and he is absolutely correct I went back and looked at your pics of the finished swingarm. The center of the shock eyes is behind the center of the possible axle lines which wil make the axle a fulcrum for the down force of the shocks so the top of the splice is what is in danger of failing. If I am not mistaken fear no evo has had some bad ass drag sportsters in the day and he definitely knows what he is talking about. And I agree with his recommende fix for this, I was trying to come up with something to fix it without destroying your powder coat job, but he is right it my fix just moves the problem somewhere else. One good thing though the metal would all be alike at the end of the blocks.definitely something to consider. Man you said a mouthful when you said" ain't customizing fun" !

Also your shock position has moved back 1"to2" back on the new swingarm, so the bike is going to sit slightly lower than before. Didn't know if you were after this or not? Sorry to be a pain but I would definitely look at fear no evo's advice!

Shock mount is only 1" further back. This will make a difference of less than 1/4" in ride height. Nothing to be concerned with.
As far as the diamonds go the splice is only 1/2" away from the axle slot.
KCgran, I'm the powder coater so redoing it is not the issue others might have having pay to strip it and do it over.
I'll look into putting a plate on the bottom and inside of the bars so it doesn't mess up the looks of the flat surfaces on tops and sides.

Maybe I'm missing something, but if you wanted to shorten the wheel base couldn't you just elongated the slots forward, move shock mounts (if necessary) and use longer adjuster studs?
I'm not sure there is much room to move a 18" wheel forward on a strait frame XLCH frame, especially w/ that 79 swing arm, but sloting seems to be strongest option to me. You could then chop a section off the ends of the tubes if you see necessary, and wrap and weld band around ends.

The 79 swing arm was 3" longer than my 62. I wanted everything where it was on the 62. It was easier to cut a section out and reweld it than doing any of the other methods. What I ended up with lengthens wheelbase by about 1". I appreciate everyone's concern but I think we are all talking extremes. I think the welds will not break nor the surrounding area for what little use this bike will see. Chevelle, I'm trying to remember if your heads are the early prototypes or the ones he did after 79 when he was doing the head/cylinder package?

Hey o1, you can always grab another late(r) model swing arm if your plan to shorten the swing arm doesn't work out. However, I too would probably run the longer/later swing as is. I say this because your machine, in its current state of tune, produces far more hp then it did in '62. This, in addition to the huge improvements in tire and suspension technology since 1962, indicates to me that your machine will be capable of far higher speeds at any given point on most race tracks. Thus, a longer swing arm might be the best bet (as several other JJB members have mentioned).

I will not agree that a longer swing arm will be beneficial on a road course. I'll buy the argument for drag or straight line racing but not for cornering.
BTW, I am still running the Boge/Mulholland shocks and vintage Ceriani forks so suspension is still old school but works fine on this bike. The only real modern upgrade is the triple 4 piston Hawg Halter calipers.

I have a both types, one bike is bolt on type Sputhe heads w/ Early Drag Specialties Aluminum cyls and a other bike is a set of thru-stud Sputhe cyls (3.625") and modified geometry Sputhe heads.

Did you buy your mechanics bike? I remember finding you a few years ago in a Sputhe search. Until recently I thought my cylinders were Drag Specialties but after taking the motor down the mechanic informed I don't have 63 ci motor but an 81 cubic inch motor. The original builder forgot to tell me he put a stroker kit in it. It turns out my cylinders are Axtell.
If what you say is true then I only know of 6 sets of the early heads that allan says there may be only 10 sets left. 4 are on bikes in his showroom, you have one and I have one. All the others I have seen were the head/cylinder package that came out after 79.

Sure, just write me a security bond for around $40k and have at it.
I sent my cases, cylinders, heads, rocker boxes, motor mount, tappet blocks, cam cover, primary cover, and clutch cover off today to have it all vapor blasted. As I printed out the label I was thinking how much should I insure this for? $500,$1000,$2000. I settled on $2k and then realized, hell I can't even replace the heads for $2k. Whats a set of good early XLCH cases go for these days. Axtell cylinders? The other parts are more readily available but still not cheap.

Never knew Axtell made aluminum cyls for cast iron xl's.
Are you saying you have 5" wheels in there?
Whats your bore x stroke?
Yes, I bought my buddies bike about a year ago. Still in process of making it mine.

Ya, thats not happening w/o welding up the lifter area.
I was thinking 3.250 bore max because he thought it was 63".
Even 3.250 is big w/o case buildup.

These thoughts are looking better now. I would also have to move the shock mounts forward. This is what I found after mounting everything up. I moved the slot back 1" from the stock swing arm so that the shock mounts are in relatively the same place. This way I can use the stock chain and the same shocks. But if you notice in the comparison pics of the 2 swing arms side by side you will notice the thicker bracing at the front of the tire well. When I mount the wheel in there I have less than 1/2" of tire clearance when the axle is at it furthest adjustment, basically little or no room for chain adjustment. My next option would to be to lengthen the slots about 1/2"-9/16" further back to gain a little bit of adjustment. This bolt on upgrade is getting frustrating.





This pic shows where the tire clearance went:

Ya like I though, on a 79-81 arm you may be able to slot the holes and gain 3/4" but not much more.
Definitely doesn't justify the questionable splice IMO.

this was a sad sight. After the money spent to build this motor and then having never fired it up to see it in this disassembled state just makes me want to cry. But I guess I should look at the bright side and know that she will make noise soon.

Good thing that has nice well blended radiuses machined at the shoulders to avoid stress risers.

No kidding, I thought that pin was a little joke! Are these reliable? i assumed the reduced cross sections at the offsets would be asking for trouble.

I have heard of offset boring the wheels for an oversized pin to get a stroker.

It's mind boggling how technology has changed since the 50-60s. Amazing whats available and what can be made now that you couldn't have then even if you had the $250K-$500k it costs for a OCC chopper.

Hey I got a fix for the tire clerence, I have a forged buel belt tensioner bracket, you can adapt it for chain, that way you just lock down the rear axel at the rear most point in the swingarm....


...Ya want it send me a P.M.......Roach.

Lovejoy makes a torsional chain tensioner too.

In the hill climbing days, we just used skateboard wheels, a home made bracket, and a couple of springs. Worked fine and we were streeeeeeeetched way out.

Anyone know where I might find a 24 tooth trans main shaft sprocket for an early XL?

I am going to run a Kawasaki EX250R rear wheel with cush drive to keep from breaking my cases. It's a 16" wheel so my tire clearance issue may have gone away and it gives me a much broader range of sprockets to use. Actually it won't change the range of sprockets as stock on that wheel uses a 520 chain and I need 530 so I will need to have sprockets made that I could have made for the Kimtab wheel., but at least I will have cush drive to soften the transition. I need gearing in the 24/40 range instead of the 21/51 I have now to reach the desired speed of 135mph.

I don't think there is room in that area for a 24t w/o a bunch of clearancing.
I would go w/ a 23t max.
Make it up in the rear.
What final ratio are you going for?

Alan told me I could go 24t without clearance issues, any bigger and there is issue. He runs 27t on his with a 36 wheel sprocket.
I'm still figuring numbers. I need to see what rear sprocket I need with a 24t trans sprocket to get me to 135mph. I'm waiting to see how tall my tire will be before I can complete the calculations.

That's not a Sprocket Specialists part# and they don't carry anything for that bike.
I have them lined up to make my wheel sprockets.
I realize now that you were probably answering both my questions. Where can I find that trans sprocket?

Never mind, I Googled the part # and found one. Thanks

A friend has made his own custom sprockets by machining off the teeth of a new one and then welding on a bored out hardened sprocket ring with the right width and number of teeth. The heat of the weld doesn't go far enough to hurt the tooth hardness.

That's what I would do if I needed one larger than a 24t. It would require clearancing inside the cover to run one bigger though so I will try and do the rest by making rear sprockets.
Ask your friend where he got the new sprocket?

o1racing03,

Chevelle'e right, 24 teeth will require a bit of clearancing... 23 teeth is max without any work to iron head cases.

Just received my 23t gear and was quite surprised at how much bigger it is than my 21. I can see where a 24 or larger would have clearance issues.

You can do away with the OEM Cover and look into the 'Lever' type cover with dry clutch actuator set up commonly used on XR750s, chevelle had a link to a fab shop that has a nice piece at a reasonable price..
this would give more wrap around room for the chain top and bottom, not sure if they incorporate the kick shaft hole? chevelle may chime back in..

Got my body worked painted finally. I was on my way to pick it up and the painter decided to add one more coat of clear to the already 6 coats of color and 6 of clear and ended up putting 2 big runs in it. Now I have to wait till tomorrow to pick them up after it dries and he buffs out the runs. It did come out the exact shade of Silver and the right amount of metallic and the perfect amount of blue pearl. You can't see the pearl at all unless the sun is reflecting off edges, just what I wanted.






You can just barely see the hints of blue in the pieces. I haven't decided yet on whether I am going to leave the fairing black or paint match it to the rest of the body work. What do you guys think. I'll post another pic of it with the body work so you can see later.


I have a set of prototype Hawg Halter brake calipers modified to go on this bike from when my buddy owned the business before he sold it. The new owner of Hawg Halters (www.HawgHalters.com) is making a new set of calipers for it because he says the old ones are just inferior to the new ones and even though they weren't his brakes the Hawg Halter name is still associated with it and doesn't want to deal with the issues in case I get hurt with the old ones. I had to make new brackets for them and now everything is getting shipped off to Calif. for chrome plating them. Works for me.

It's going to have a reflective blue vinyl stripe down the center like this:


And Harley logos on the side of the tank to match:


And matching show stand like this but with the wider center stripe:

Fitting the new Kawasaki EX250R rear wheel to it. Lots of machining to make this fit correctly and I mean lots.I love custom chit. Had to recess the bearing in the cush drive in .306", take .306" off the spacer between the cush drive and the wheel bearing,and .306" off the lip where the seal goes to move the wheel over to the right to center it. Now I have to shave some off the caliper bracket on the left to fit that side. The Ex250R swing arm obviously is wider than my XL arm. The EX250R axle is not long enough so I won a Harley softail axle and will have it turned down to 15mm and then it should all go together.

I was reminded by Alan how weak the tranny cases are on the early XL motors. After discovering I had a 1325cc motor and not a 1032 he highly recommended a metric bike cush drive to soften the blow of shifting for any performance runs such as my mile record attempts. I will keep the Kimtab on the bike for everyday riding and for shows and such.Last thing I need after all this time is to blow a case out of this thing.

When the motor builder dropped off my parts he did point out some welding in that area. I don't remember if it was just damage repair/speedo drive hole or if it was the preventive maintenance sleeve repair. My engine parts are on their way back from Oregon and I will check that when they arrive. I will try and get the sleeve repair done if it hasn't but still run the cush drive for racing. I've done this wheel install and removal so many times now I think I can change wheels in about 3 minutes.

It would be purely for the knowledge of knowing. I know I can't afford it. The guy who built this motor was very knowledgeable with these old motors and I assume he did this fix. I remember back then that issue and repair method and think he would have done that knowing how much motor I would have. My memory from 35 years ago is vague at times.
as I mentioned there was some welding done in that area , until I get them back I won't know how substantial the repair was.

I don't have a kickstarter and all the mechanisms and parts have been deleted. It's just as easy/cheaper to get a different rear sprocket than deal with the issues at the motor.

I was looking at some bar end mirrors on Ebay. The only ones I could find mount inside the end of the bars. My Tomeselli clip-ons are solid so they wouldn't work. Well, I lucked out. I contacted the manufacturer of these cheapie Ebay China mirrors to see if the inside the bar mounting can be removed and then clamp the mirror to the outside of the Tomaselli clip-on. They told me they didn't know but probably not. I took a chance and spent the $15 for the pair and figured if I had to machine a 7/8" hole in the mount to make them work that would be easy enough. I finally got them today after 15 days and took them apart to discover that by removing the inside the bar parts and the slug that gets sandwiched between the 2 bracket halves it would bolt right onto the clip-on. The funny thing was one part was missing from one of them so they will probably refund my purchase and give them to me for free.

Here are the 2 mirrors, one disassembled showing all the parts:


here are the parts I deleted:


And the mirror mounted on the clip-on:

Those all mount inside the bar end. I can't use that kind with billet clip-ons. Chevelle, did you read the post about the trans gear cover? Someone said you had a set up I should check out for running a 24t or larger sprocket. Do you have any pics of it or a link to any info?

Paint is back and I have already laid the graphics on it. It came out sweet. You can't see the blue pearl in the pics but only in the sunlight which is how I wanted it. All the graphics are reflective vinyl. The HARLEY DAVIDSON name is white reflective vinyl and looks almost the exact same color as the silver until the light hits it and then it looks whiter.

It definitely will not be a daily driver. It will probably scare the chit out of me every time I ride it for fear of hurting it. I believe the 35 year wait will have all been well worth it for sure. I can't wait to throw this back in my old mans face who bugged me for years to sell it.

New Hawg Halter modified calipers and brackets. I lucked out because the new rear bracket has a separate anchor bolt hole on the end instead of my old bracket that used the caliper bolt hole as an anchor bolt hole also. When I welded on the adjustable fore and aft bracket I welded it too far forward. This new bracket gives me back the 3/4" rearward adjustment I lost and needed:


Front calipers were first gen and they have been beefed up since then and the new calipers didn't match my "sandwich" bracket so I had to fab up some more brackets to mimic the caliper contour:


Mounted the bar end mirrors also:

No word on the motor rebuild, I'll check on it tomorrow. Everything else is pretty much at a standstill till I get that in the frame and wrap the other 100 things off the To Do list.
I had the motor parts shipped right to the shop so I haven't even seen the parts back from vapor blasting.

Sad isn't it? It's enough to make you want both a "thrasher" and a "looker." The first ding, little or small, can be a relief in some ways.

I was searching for some old photos of my old Triumph chopper when I found these long lost pics of my Sportster before and during the new build. I discovered a couple of interesting things in these photos. The first being pics of my original smoked acrylic fairing that disappeared when my bike was shipped to me from Ca. to Ga. More on it in the 1/4 fairing thread. The first pic is a pic my brother took of me wheeling past my house back when people said you couldn't wheely a Sportster;


This pic shows the bike when I first modified it to a cafe racer. It had the Ceriani forks that still are on it as well as the Kimtab magnesium snowflake wheels and the XR750 seat. I had the XLH 4 gallon tank on it and the old single piston Hurst Airheart calipers. Thats me in the pic when I was 22-23, I'm now turning 60.


The next pic is of when I started the current build in 1976. I had the frame modifed and had the engine built with the Sputhe heads. Interesting thing I saw in the pics is when I bought the seat I don't remember the back of it being closed, Apparently I cut the hole to use the compartment for tool storage. I have seen reproductions of this seat and the underside is open and has no closed floor to do what I did here. I'm not sure if that is the actually aluminum oil tank or a white cardboard mockup of it.




.
This was a daily driver as I had no other vehicle at the time and was very "competitive" racing through Mulholland canyon on the way to the Rock Store and the beach every weekend. I would come out the last bend before the Rock Store and pull the front end up and wheely past the store doing about 60mph. I am mistaken about not having another vehicle because I remember I had the 78 Suzuki GS750E at the same time and would alternate weekends riding them both. It was fun showing up on the Suzuki and listen to the guys who didn't know me talk about waiting to see the freak that would wheely past there. I would play it up and say shit like " ya , that guy is gnarly and can ride the chit out of that thing"

Here you can see the cutout hole for storage where it will now house the battery for my total loss electrical system as the new build has not starting or generating system. I think I am going to find some more of those blue Oakley hand grips for this bike.

Man that bike looked amazing back then and your build now is even better. Stunning. Can't wait to see some new pics of you pulling up the front end.

It took a technique to wheely it when it was 55hp and 500lbs. Now its 100hp and 360lbs. I think it will now take technique to keep the front wheel on the ground.

You are correct, total loss with about 4 hours I'm guessing of running lights and then plug it in the charger. I doubt I will ever ride it 4 hours at a time so it probably won't be an issue. I played Texas Hold-em at the local bike dealer on poker night and won a Battery Tender for finishing in 4th place (3rd place from my table but 4th over all out of 48 players). So my plan is when ever I'm not on it it will be plugged into the Tender. It's nice not having to have ANY wires to make this run other than spark plug wires. The magneto creates all the spark needed to run the motor without any other wires needed. I only need one wire for the kill switch. The lighting/horn/gauge computer will have it's own harness to the battery. The generator/regulator box was 14lbs of unnecessary weight we threw in the trash.
The rush will come with a few tears I am sure when that baby makes some noise. Until then it is just aggravatingly slow anticipation.

Drag, I just realized the pic you posted was an enlargement of a section of a pic of my motor. That was when I had the stock motor and before the Sputhe heads. It now has the magneto mounted in the generator hole like the XR750, with no charging system. Still waiting to get the motor back any day now. This is really frustrating. Just missed another race weekend.

I already had that planned that there is no way I could fire this thing for the first with out it being caught on video. I'm sure it will be an emotional long awaited moment for me. The culmination of a dream I could never afford to complete. It's a real shame that the original motor/frame builder is too old and in the advanced stages of alzheimers to see his dream fullfilled.

This motor builder only had the task of disassembling it and then reassembling it. 9 months is way more time than even an artist needs to complete the job.

I was asked to give 2 of my $25 off gift cards and to donate something to auction to benefit the United Way for a Poker Run today. I decided to donate the Harley Davidson toilet tank I had done a few years ago. It fetched $100 for the cause, I'm happy with that. This was a white tank that is done completely with powder coating.

This is getting really frustrating. After 11 months with my motor he has it back together but now says the pistons are hitting the valves. He is trying to figure out what to do to fix it. He mentioned stroker plates under the cylinders or new pistons. I think machining the face of the piston would be the easiest fix. Any thoughts from you guys? At least he sent me pics of it and it does look sweet after all the vapor blasting, but I would much rather hear it make noise than look good. Right now all I have still is a very expensive boat anchor.

No, it was fresh build in 1977 and then I ran out of money and put it on the back burner before it was ever fired. The guy who built it knew what he was doing and I can't believe he would have made this mistake.
I'll gladly pay the $65 to flycut the pistons I see in the link you posted.

Wow, I wasn't expecting it to be that inexpensive. I emailed them to see if the $65 charge was per valve, per piston, or what. They emailed back and said that was the price for 4 pistons. So to do mine would only be around $35.

Well that bubble burst quickly. They just replied that they don't do motorcycle pistons, WTF. Aren't pistons pistons?

Looks like Toyota specific site.

You say the pistons are hitting the valves, but has he determined the valves have clearance in the heads at TDC (cam specs)?
I would make sure that TDC clearance is established before continuing on, you may get some needed clearance by sinking the valves if needed for TDC clearance.
Has he shimmed the cyls to determine what is needed for clearance?
S&S pistons?
What stroke is this again?

They are rare Drag Specialties cylinder. Motor has a 4-5/8" stroke, oddest length I have seen. It is the one thing the original builder(1977) failed to tell me was in the motor. I always thought it was 63ci when in fact it is an 81ci. He used clay to make the determination that it was tight. I need him to use plastigage or something so I know what the clearance actually is. I am unfamiliar with shims at the base of the jugs to gain clearance but will start doing some research tomorrow to see what the best fix for this situation is. I think fly cutting the pistons might be the easiest and cheapest but I'm not a Harley engine builder.
You have the same 77 model heads as mine, correct? They were different than the ones in the package of heads and cylinders he started making in 78 and marketing in 79. What is your motor combo and have you dynoed it?

4&5/8 x 3.25 is 77 CI.
I don't think you should have clearance issues w/ 4.625 stroke?

Alright, after going through all related parts again he finally determined the original builder put my stock rocker boxes on with the stock .330 lift valve springs. Valve springs were all binding. Ordering high lift springs and hope to make noise next week.

Don't know if that is even conceivably possible after 37 years. thanks for the video though. I would still love to own a real original XR even though mine might be pretty bad in it's own right.

Healleluja, I'm, picking it up tomorrow. He's putting the primary gasket on and buttoning it up right now. Finally get to see what it looks like with the new paint scheme. And then the hundred little things to tie up this build and make some noise.

There is an allen plug on the front of the iron head rocker boxes. Is there oil pressure behind them and can they be tapped for an oil line to a pressure gauge?

Yes, if you want to worry yourself to death that there's no oil pressure, you can put an oil gauge there... It will show about 20psi cold and nothing once hot cause Sporsters don't have oil pressure to speak of, just oil circulation...

A much better way to check for oil circ or not is to put your hand on the oil tank from time to time...
Cold = probs
Hot (preferably VERY) = OK

Manual says running pressure is around 10-14psi. and 3-7 during idle.
Frenchowl, if the oil stops circulating how long do you think it will take the oil in the tank to cool and give me an indication there is no circulation. Much longer than the pile of scrap parts would tell me after it has blown up from no OP.

Cool, so a -3-1/8npt fitting and a braided steel line going to a 0-15psi gauge on the dash and I'm good. Running this thing wide open most of the time I will have a little more comfort being able to monitor OP both by gauge and idiot light.

I have my doubts to the accuracy of a 60psi gauge when it's reading only 5psi. Running 20psi to a 15psi gauge I doubt will damage it. And if it is pegged I know I have enough OP.

Look at it this way, how many road racers you know are fitted with an oil pressure gauge?

Either you have confidence in your engine, or you will crash cause you keep having a doubt and keep having a look at that dammed gauge... And then, see above, wonder if the gauge is reading right ;-)

Been riding fast iron heads for the last 30 years w/o gauge, had a lot of breakdowns but never an oil pump failure...

You should be more worried about how you're gonna check the engine assembly work for yourself... Cause the guys assembling it won't be risking their own balls on it, you will...

I'd gladly take a look at this alloy marvel but I'm a tad too far away over the pond...

Did you get in touch with DR DICK as I suggested before???

As for how long it takes to notice no oil in the engine, I can tell you from experience... Once, in a hurry, swapped oil in and out on top of gearbox... Did about 20 miles before rear piston started to bind... India stone on the piston and new rings was all what was needed...

Sent a message but got no reply. While a pressure gauge may not be critical on an iron head as a long time auto racer knowing oil pressure is paramount, once gone results in almost immediate damage. Having the gauge will just give me more peace of mind just so I know when there is a change in the norm. They told me the same when I put an oil temp gauge on my VW race engine. The mechanic told me all it was going to do was freak me out at how high the temp was all the time. I wasn't so much interested in the number but more so when there was a change from norm either higher or lower.

I run one like this 30psi one:

Just to update. The builder swapped out the stock valve springs for new high lift (.480) springs and, after shimming for proper height and pressure, buttoned up the engine and I picked it up with the assurance that "It is ready to fire". Now a few weeks of me parting the rest to finish and I'll fire it. I'm now at the point of bolting everything up for final assembly. LocTiteing everything and putting fluids in (forks, brakes, engine/primary,fuel). The hand held starter is being made right now.
Anyone have a spare rocker shaft end cap? I can't find the one I replaced the gauge adapter with.

After 20 years of auto racing I know how to put a gauge where it can be easily read without taking your eyes off the important stuff. No one is going to talk me out of having a gauge and idiot light. The gauge is not so much for running but for warm up and break in/tuning and such.

It's a dry-sump roller motor, not a plain bearing automotive engine. Honestly, how many oil -pressure gauges have you seen on a true high-performance Harley engine?

Well, finally got the motor back after 14 months. I have it back in the chassis and everything mocked up. I need to plumb the fuel and oil lines and hopefully next week my friend will have my new hand held starter fabbed up for me. He is battling kidney stones and took this week off. Here is what she will look like on the street. Once I get everything sorted I will mount the full race fairing. Once everything is plumbed I will borrow one of their other starters to get this bitch making some noise, I will not let his kidney stones slow me down at this point.

No Wheelies .... No Burn-outs ... and No 100 MPH runs out of the Gate...

I'll baby this thing for a little while but I do remember asking the original builder about how many miles I should break it in for. His response was "right out of the gate, ride it like you are going to race it"

I have set of Sputhe pressure relief valves to go in the heads to ease in bump starting this motor. I bought them after I discovered it was an 11:1 cr motor and pump starting may be difficult even in quality tune. The engine builder, I think, didn't have the confidence to try and machine them (drill a hole and tap) into the heads. I'm okay that he didn't if he was not sure of what he was doing. I hate to have to sue him for a set of Sputhe heads. The plan is to run this for a year or so and then pull the heads for porting, I'll install them at that time after knowing how hard it is to bump start.

Here is what she will look like on the street. Once I get everything sorted I will mount the full race fairing. Once everything is plumbed I will borrow one of their other starters to get this bitch making some noise, I will not let his kidney stones slow me down at this point.



Can we get a detailed look at this hand held starter?....built a drag bike and I would like to build one.....thanx

The hand held starters are basically a car starter motor bolted to a plate with a handle on both sides and a push start button on one handle. Instead of a gear on the end of the starter picture a 1/2" drive 6" ratchet extension on the end of the starter. I have a female 1/2" adapter on the crank shaft. You just plug the extension into the adapter and press the button to spin it over. I'll post a couple pics to give you an idea on some. Mine will be more horizontal than these stand alone, set on the ground ones but you'll get the idea.



This one is set up for left or right side adapter or for motors that turn counter clock wise.


Here you can see the crank adapter:

So I go to put the chain on tonight only to find that with the 23T sprocket the chain hits the boss where the lower cover dowel pin is. I am going to have to grind some clearance there.

Why build an engine that can spin and then gear it so it can't???

For me to know and you to read the posts to figure it out. Do you ever have anything positive to post?
Gearing has no bearing on whether the motor will spin or not. Just where it will spin.

I will run the 21/51 for initial run in on the road. I'm glad I saw this issue now though so I can correct it and not discover it later prepping for record runs. I am also seriously considering taking the 79 swingarm off and making a brace for the stock arm and putting it back on. Similar to the one on my Honda (see below). The 79 is configured in such a way as to give me little to no chain adjustment and I don't like that.

Nope, Got my starter finished, went to pick it up, got home to find it turns clockwise but my motor needs it to turn counter clockwise. When my buddy called to say it was done I showed up to pick it up and was told his boss now wants to charge me for it instead of the sponsor/ barter deal we are on, WTF. How much does he want for it? $350, WTF. So I'm glad it spins wrong. I found a Chrysler starter that spins CCW and I'll have my buddy make the other few parts I need so I don't have to pay for it.

You were right about the spark plugs, I checked and they are way too long. I'll go back and see what you recommended.

Too bad it wasn't setup w/ a kicker.
Could always remove the kick arm and pedal for weight savings, and just leave the kick shaft, spring and gear in primary.
Would have to make a fold up right rearset , and get creative to clear rear carb but that shouldn't be a big deal.

When I was looking at buying a car lecky starter for the bonneville bike, I was told starters for any car turn CCW ""except the Porsche ones""...

Your mech must be a star to have chosen the only bad one of the lot...

Somebody gave me one and I made the frame out of square tube from an old desk, materials' costs: zilch..., more like it!!!

Now I like that swing arm. Glad you posted this as I have been thinking about shortening a rectangle tube swing arm and really hadn't considered that the how the chain links fell dictates the length of the swing arm. Thanks.

I've been broke and unable to put any money in this. I finally got a side job as Night Manager of the new O'Reilly Auto parts store opening in my town and just bought the oil I need for the motor. So it's slowly coming to a point where I can fire it up. The first time it makes noise will motivate me to just tie everything else up and finish it.
