I'll show you the races I do in the trophy of the mountain.
In this video I made a bad fall because of me, as I have not plugged in properly 3 rd gear, the bike, I was going straight, and I had to throw myself on the ground for not hitting the rocks.

After the bad crash, I adjusted my bike, attaching the exhaust with a wire, I straightened the fork, which was wrong, fortunately did not bend the stems, I removed the earth and grass from inside the carburetor, fortunate that the inlet valve was closed, I straightened the right footboard a bit 'as best I can resetting the brain to make a good race, I would say that I did: I won the category, making even the absolute, of all vintage and classic motorcycles.

myself after I realized that my helmet was very spoiled........ :shock: and I understood the reason for this excellent performance. : :mrgreen:
shortly, will also put the video where I had the best time. Carlo

Hi Carlo

nice dry clutch . what are the primary gear ratios ?

i have some dry clutches laying around from Franco Verni from Forli and they have a 56 / 26 = 2.15 ratio

i like to speed up the gearbox so there is less load on the gears . i am looking for something around 1.8
or 1.9 ratio

here is a picture of the close ratio gearbox i had made for my 500 .

and another picture from a close ratio gear versus my gears

regards Eldert

I have to ask,
How do you get 500cc by boring a 450? (88mm and the liner is thin)
Do you bore the aluminium cylinder and insert a larger iron liner?

going to 500cc what is the weak point or points in the engine?
What do you do to strengthen the cases?

graeme

any pictures Eldert?
