wow, looks nice. tnx alot!
What about the clearence of the block, probably its very close .
do you have any footage of this clutch in action?

I know that alot of you are racing and its a secret . Its hard to make a good competitive clutch.
Can anyone show me some pics of modified clutches. (for racing)
i have some good ideas, but i would like to see yours as well so i can decide wich to build.

Best regards

Is there any difference between these two exhausts in performance.

thanks for the advice and expalnation.

Hi!

Is there any difference in performance if you remove the wall of the booster?

Hy,

Some progress:

The ignition will be from ignitech fully progr.

Here you can write, what kind of carburettours do you use on your Tomos?
Im using Dellorto UA 18 on a Tomos A35 sprint and its fully hidden inside the covers .

Back again .
The attachment for the carburettor will be made from rubber, the carburettor will probably be a Dellorto 28-30mm or Keihin.
I will post some pictures when we will progress.

No i didnt cast the cylinder by my self. Some other guy cast it now he is retired. The mouldes are from another guy. We have 4cylinders, 1 with normal intake(tomos DMS), 1 with intake on a side (tomos D6) and 2 for rotary valve. The nicasil wand is missing on this pictures because these are old pict...

It fits, but you cant get this cylinder. There was just a few made. Just for racing prupose.

Me, my father and older brother.
Each has his own bike. I own RS80, and tomos A35 sprint.
We build racing tomos bikes, each contributes some time and ideas.
