my 2010 yz450f is doing some strange things. When I start the bike up cold, and ride it a little the clutch is fine. After it warms up and I ride it pretty hard, the clutch feels halfway engaged. If I wasnt holding onto the bike, it would take off without me while holding the clutch lever in. Its bad enough to the point that It will die if I stop while in gear and the lever pulled in.BUT, when I give it some throttle, its totally fine. you can feel the bike jerk back and doesn't feel half engaged anymore. As soon as you let off the throttle, the bike starts pulling forward again and wants to die. You cant even find neutral with it running because its grabbing so hard.
Oh, and I can tighten the play up on the lever until It feels uncomfortably tight, and it makes no difference. all of the symptoms I have described are with the bike idling at a stop, in gear with the clutch lever pulled in.
