when i was putting my bike away for winter i washed it and then rode it around in a parkinglot of about 10 mins to make sure there was no water anywhere there isnt susposed to be. Well it got nice again and when i took it out the clutch will not engage so i took it all apart cleaned it up re-oiled it put it back together filled it up with oil and it still dosnt work, i forced the bike back and forth and it eventuly rolled freely with the clutch lever pulled in but as soon as i stoped rolling it it locked right back up again i have no idea what is wrong and none of my freinds do either if anyone else has had a similar problem or knows what could be wrong i would like to hear from you. Someone told me that the plates could be so worn out the presure plate is bottoming agaist the inner hub but when i had it apart i measured some of the plates and they were well over 3mm.
