Maxi N rebuild

My Maxi N has been great to me, I haven't had to fix much in the last 3 years. This last month it has been rattling it self apart and breaking stuff.  I had a death vibration last month and it was from a flywheel loosing its inners. Then a flywheel center lobe came loose and gave me a advance/retarded timing problem with a clacking noise at idle. I also had a cracked rear rim. I am fixing these issues and should be good to go for while.

Here you can see the center is loose. 

This is the last one with the pieces falling out. 

This is the rear rim with the center crack.
