So... I think all of my clutch questions have been answered, but there is one more issue I am trying to diagnose. At lower RPM's the bike is a bit jerky. The engine seems to be running smooth, but the bike seems kinda clunky, hard to describe... As soon as I increase the rpm's a little, or downshift, it smooths out again. I've checked chain adjustment, and the only other thing I've changed is putting on a Moose CS sprocket, but it had the same issue with the old sprocket also. Am I just lugging the engine too much, or do I have worse things to fear?
