drive train "slipping" problem, help needed

[buckiav8r]

I have an '81 650GLX with shaft drive and about 22,000 miles on it. It started to feel like the clutch was slipping once in awhile but almost all at once the thing started slipping full time. Bike runs fine but doesn't go anywhere, in any gear position. I pulled the clutch housing off and find that the clutch itself is in good condition. With the rear wheel on the ground and the tranny in gear I can turn the sleeve hub by hand. I pulled the driveshaft boot back and while turning the sleeve hub the shaft doesn't turn. Seems to me that something in the tranny is stripped. Does anyone have any thoughts as to what I might be faced with next? I have a Clymer manual for the bike but am a bit daunted at the task of splitting the case. Any help would be appreciated. Mike

Sounds like a secondary reduction gear failure. You aren't the first; there have been a few 650's around here with that problem. Good news is that it can be fixed, but it's a farily big job. You might want to try the search function to turn up more info.
