take the clutch cover off and try to see if it's releasing the clutch's with the bike off of course. it also can show you whats going on etc..
i did a clutch not to long ago on a bike and it had a little ball bearing that fell out. it was in the middle of the clutch pack. it would push a stem out releasing the clutch.. it would be very ez for it to roll out and you'd never know it...


i'm sure steve could help you more..
