Hi, I have a 1972 CT90 with a clutch that never seems to diengage. I've triple checked everything and scoured the interwebs and I've seen a number of people and posts with the same issue but never a resolution. When I shift it into 1st gear at idle, on the center stand, the rear wheel spins with some force, with the shift lever all the way down and when it returns to the up position. But the bigger issue is that when I press down and hold down on the shifter in any gear at speed it does not disengage the clutch, to allow it into neutral. I should be able to press and hold the shift lever and rev the throttle freely without any effect at the rear wheel but the clutch won't let go and instead it lurches into gear. I understand the mechanics of pressing the shift lever down, which rotates the cam plate up against that thing with the three balls, which then pushes the entire clutch housing inward to the point that the bob weights in there no longer contact the clutch plates, which should free up the clutch so that everything freely spins as long as the shift lever is held down. And the clutch has been adjusted by turning the adjustment screw counterclockwise until friction is felt then clockwise 1/8 turn and locking it down. But it all doesn't seem to be working right for reasons I cant figure out. I believe the clutch was assembled correctly, verified by off the bike it turns in one direction and locks in the other direction. The shift drum stopper arm and plate are also in good condition, no loose screws in the stopper plate or anything like that. From all that I can tell I'm the first person to go poking around in the right side of that engine so I don't think it's an assembly issue. All of the screws on the case were in good unstripped (but corroded) shape and it looked to have the factory gasket. When I got the bike, after getting it running, it was both lurching during shifting as described above, and slipping when kick starting it. I replaced the clutch pads and now it doesn't slip when kicking but it does continue to lurch when shifting. I found one post online where the poster had the same issue. They swapped out the clutch bell, but also the oil pump, and it corrected their issue. Would the oil pump have some bearing on this? I've put several miles on the bike and it hasn't seized up so I would think the pump was working, but maybe its not 100%? There was quite a bit of sludge internally at the bottom of the right side and on the filter screen which I cleaned out when I replaced the pads. Sorry I know thats maybe a heap of info to take in but just wanted to let folks know all that I've tried and considered and see if anyone else has any ideas. I suspect anyone that has dealt with these autoclutches may have some insight, CT90 or otherwise. Thanks!
