Now on to the clutch. First problem is snapped or flattened threads on some of the little bolts that connect to the clutch cover.

Others may disagree, but I believe you could forego the cover. If so, I'd say remove all the nuts, shave off the stud that's broken in the photo plus the one that's 180 deg. opposite (for balance).

You can run it without the cover. I prefer to run with the cover (a few missing nuts won't hurt) as I think it adds rigidity to the basket. I've seen the odd one spread a little causing the plates to rattle.
If you go without the cover make sure the oil you use is NOT friction modified.
Cheers
