I did take apart and reassemble the clutch. Do I need to lube each plate/pad up before reassembly? I didn't have a piston stop to tighten the clutch nut very much, so I think that may be an issue as well. I will check to make sure the cable is not stuck in the clutch bell, but I don't think that it is. I'll also check the flywheel asap and let you guys know more.
