We had success! The 3 pieces all fell out and the bolt went back in without issue. Towards the end I was worried because it wasn't coming off, so I did what any good backyard mechanic would do...Hit it with a large rubber hammer and it fell off!
MetalStudman I couldn't have done it without you!
Funny how the top of the motor looks clean and the bottom is just caked with crap. I spent about an hour today talking to machine shops and found one that will build me an adapter shaft with both sets of splines on it. $350.00 with heat treating. Now I have to mock it all up and get messurements. Also this motor is at least 20 lb's lighter that the original 250cc.
lb's = hp
