Hey guys,
I got the epi clutch kit in my clutches, orange primary spring with 50 gram weights,
Purple secondary spring, not sure on the angle on the helix that comes with the kit.
I got 20 top gear, 40 bottom gear in the chain case.
My issue is that Im only hitting 7000 rpm at wot.
Is there anything I can do in the clutching to raise it to around 8000 rpm?
Thanks

Sorry guys, its a 1998 polaris indy 500

what gram weight came out of it before u changed them

 

[kawarthaslednec]

stock weights were 48.5 grams, so its only 1.5 grams heavier now.

Peak usable rpm is 7800 on that engine.
Did you also change the secondary spring to the next stiffer one?

try putting your stock weights back in the clutch!! i know its only 1.5 grams but the motor might now be able to rev that big of a weight
