Last weekend I blew out my clutch in my '03 yz450 in a local enduro-cross. I started to feel it fade, as in not disengage until the lever was closer and closer to the grip. By the end of the lap my clutch would not disengage and letting the bike cool off did nothing. I was told I need to replace my plates. It seems to me that worn plates would make the clutch slip, not only be engaged. Why would worn friction plates make the clutch only be engaged? Am I barking up the wrong tree? Any advice would be helpful.
