I've got almost 13K on my 2003 Vulcan and the stator needs replaced. What else should be done while I am involved with that? Maybe a clutch rebuild kit? I have noticed an occasional growl from the clutch when I let it out, but only when it is cold, and it sounds like it is coming from the left side of the engine, from the riding position. Maybe lube the spline? I'd appreciate any input.
