Top speed is not going to be affected with performance clutch springs, they will affect you off the line performance. Going with stiffer clutch springs keeps the clutch shoes fromgripping until the rpms are higher. I think of it as reving you motor and popping the clutch on a manual shift car to burn rubber. It will not increase upper end rpms or top speed.

I would bet you will like mods to the variator. Give that a try.

I know this is an old thread. But how can I find a combination of cam, variator , Clutch springs that would give me more top end on my Linhai 257cc JCL scoot.
