I thought i had a HPD cutch kit..I DONT! its a EPI, the catolog says for stock engine and stock pipe, it only makes since then that is why my atv is still a terd? im not sure what to do, spend the $ for the HPD kit o stay with my EPI.

 

EPI clutch kits are designed for stock motors. There kit is probably not even letting your modded motor hit its power band. Better try the HPD.

 

HPD

 

I would say that the EPI clutch kit is not letting your quad
get into the RPMs that your modified engine is producing now.
Get in touch with Darrell at HPD or Rick at RCR and they should
be able to correct the clutching problem.
If you get a bigger carb go with the 35 PWK Kelhin and a Velocity
Excelerator from HPD!!!!!!
