1. It looks like the dimpled bushing is inside your primary drive gear in the above picture, sometimes they get stuck due to oil stiction.


2. Usualy there is a collar next to the crank bearing, but are the rear drive teeth for the oil pump correctly lined up with the oil pump gear in the above pic?


3. You shouldn't use an impact gun when installing the clutch nut, it may cause binding against the crank bearing.

The rear teeth are lined up OK, but if a thin collar were missing...one not much thicker than a washer, the teeth could still line up. I can't fine any videos of rebuilds that match this setup. All the vids have different primary gear with a thick, stepped collar. If only I had an exploded view to reference! This is how the bike was when I got it, but I have no idea if the previous owner or shop that worked on it knew what they were doing.
