The clutch on my neewly bought 77 XS650 feels quite good. The whole thing was rebuilt to years ago and it's used just a few miles after that. There are no problems when I'm riding and I always find neutral. I started the bike on the center stand last night and put it into first gear with the clutch engaged. The back wheel started spinning. It's not enough to make the bike go forward with the back wheel on the ground, and I can stop it using my hands. Is this supposed to happen or do I have a clutch issued going on here?
