I would really appreciate that or clutch cable specs from your '91. So appeciated! Also, upon further investigation I came up with the following diagnosisFinal diagnosis: Found out why the clutch would no longer disengage, even manually pushing the lever on the case - previous owner connected both the breather on the carb (cylinder vacuum) and the breather on the tranny with a tube. bike ran great, but when running, it sucked tranny oil in to the carb (which explains the blackened spark plug). Then when the bike was shut off, anything at the top of the carb would push out through the breather hose and back in to the tranny- which explains the milky oil in the tranny sight glass. running the motor as long as i did during inspections sucked enough tranny oil out and burned through the carb, depleting lubrication in the case. hence, no disengagement of the clutch. lots to do this weekend, but i think im gonna have a competition-ready bike soon!
