I have a 2006 YZ450. I have replace the entire clutch(Barnett carbon fiber), inner basket, outer basket, Stopper lever, and boss. I have an inconsistant problem. The clutch just doesn't seem to disengage. I just don't know where to look from here??? Unless it could be the actuator arm or push rod, I just don't have a clue at this point? Thanks for your help.
