So, I just rebuilt my motor (because of top end issues) and I split the cases to replace some seals. I pulled out the entire clutch assembly/transmission as a whole, didn't disassemble anything. Just got it back together yesterday. I went to go for a quick ride, and when I pulled in the clutch, first gear engaged but the bike did not move forward. I could actually push the bike easily when in gear. Next, I adjusted the clutch per the manual. Now I can't push it when in first, but when I pull the clutch lever to disengage the clutch, I still can't move the bike. It shifts from first to neutral to second and so on just fine. No noises while running either. Bike is a1972 CB750. I never had any clutch problems before. What am I missing? Could the cover be on wrong? Plates stuck together from sitting 2 1/2 months?
