Good evening,
The bike is running again. A welder welded both parts for me with MIG, but I had to redo the flywheel with stick because he was not able to see in there. I machined and lapped them. I was planning to spend hours hand filing the flywheel keyway, but realized I had a hacksaw with a deep enough throat and could stack four blades. When I was setting up in the vise, I realized I could use a piece of plywood that needed behind the flywheel as a guide if I cut a slot in it. Took 10 minutes and made a very nice keyway I had to file about .005" wider to fit the key. I made an aluminum key for it.
In the process of putting it back together I found what happened. I forgot to put the washer behind the gear nut and the gear had heavy rust damage to the unused threads and made me think I was tightening it.
I almost did the same thing on the repaired parts, but this time I was checking fit up and making sure there is enough thread because it ends right at the flywheel and now my flywheel is a little further on the taper from the repair clean up and lapping.
I ran it for a while and checked and seems to have stayed tight. Also used blue thread locker on the nut.
Thank you,
Scooter
