i've got an 85 xlx 61 that's acting up. if the bike is in gear, and not running, clutch lever pulled, it won't move. if i start the bike, this problem goes away instantly. i have adjusted the clutch and cannot make the problem go away. anyone have any ideas as to where i should start to investigate what is going on?? i have been told that it may be the ramp and ball that's wearing. any help would be appreciated.
