I'm working on this old 85 rm250 thumper and I think there is a big problem with the clutch. When I pull in the clutch the rear wheel wouldn't move when in gear. Also when I went to kick start it the bike moved forward when in first while I had the clutch pulled. I figured the clutch was just loose. When I tightened up the clutch cable and pulled in the clutch lever there was a loud click and the cable went slack. I tighted it up again and pulled in the clutch lever and again it made that noise and went slack. The bracket that connects the clutch cable to the clutch pin is fine and I can pull it forward by hand a little and it does return to place. Does my clutch have to be rebuilt? Any ideas of what may be wrong. I have the right side case off and I'm considering removing the clutch and checking it out but I don't have then manual for this bike yet "it's on order and should be here next week". Any links on removing and installing a clutch I guess would be great unless there is an easier fix.
