I've run into a dilemma. The bike started leaking oil last Friday and after nursing it home and correcting the source of the oil leak (failed clutch actuator pushrod seal) I also wanted to replace the chain and sprockets (they're shot) while I had things apart. Problem is I am unable to break the countershaft sprocket nut loose. Following the shop manual instructions (stand on rear brake to lock things up) did not work. I next placed a padded pipe through the wheel across the top of the swingarm to lock the drive line. Still can't break the nut loose. And I'm using a 17 inch breaker bar with an extension, so I have a LOT of leverage.
At this point I'm not sure what to do. I even went and re-examined to make sure the nut is not reverse thread (looks normal to me, judging from the little thread I can see). I'm very worried that any more force will break something else (something expensive). My next option is to cut the nut off with a dremel tool and a chisle (cut the nut almost to the countershaft trhreads and then split it with chisle).
So, if anybody has any suggestions I'd love to hear them. (And I have considered heating the nut but am concerned about the proximity to gasoline, and excessive heating of the countershaft etc.) Or maybe you can just point out that it is reverse threaded (and I'm on drugs I don't know about). I won't mind feeling like an idiot if I can get this resolved.
