I have a stock 2003 KFX80 it runs fine, but has lost some power this year. The compression is100 psi cold and 115 warm what is the psi when they are new? Thanks!

120+

Have you serviced the clutchs?

No bottom end? No top end? Cleaned carb and air filter?

I did double check the psi readings today with another gauge and it only changed 2 psi when warm. It has never been rebiult but I think its time. As for the clutch I thought if it wasn't slipping it was good. Something tells me I need to look in to that. Thanks you for the info!
