...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
