    How tight of a fit is the clutch hub to the clutch ring gear?
    There should be no more play than 1/2mm or 1/16in. Any more than that and the clutch hub/ clutch assembly is shot.
    I ask because if it gets really bad, the teeth on pinion gear attached to the crankshaft and the teeth on the clutch ring gear will not mesh correctly and will ride up on each other. In other words, they will disengage from each other and instead of the teeth meshing tip to valley, they will grind tip to tip. The very beginnings of this are "popping" sounds as the teeth occasionally slip past each other. It will only get worse as the wear increases, especially under load.
