After being warned to check the crankshaft taper and rotor. I finally got the correct flywheel puller tool and did just that. Both surfaces were slightly galled indicating that it had been slipping. I used emery cloth on the crank taper and modified a sanding drum to match the rotors internal taper. I removed the high spots and re-assembled with a dash of red loctite on the taper and orange on the nut. A previous owner had apparently been in there before me, the 3 allen bolts were already loctited in and I could see wear in the sockets from the allen wrench.
Aside from new parts are there better fixes? After learning a few GS things I would probably buy an 83 1100 or an 1150 if I was to do this again.
