Well a friend came through with an impact wrench and 30mm socket, so the sprocket is off..... in fact... the whole motor is out!!
The only problem I had was with the swingarm bolt. I had used jackstands to hold the motorcycle up and mounted them too the swingarm. After the motor was completely unbolted (except the swingarm), I had to move the Jackstands to the frame. It was a delicate ballet between jacks, and motor and stand.....
Before that, I couldn't figure out how the exhaust pipe came out because it was all one welded piece..... I found out someone did some customizing
......and missed a spot......
so now I'm off to eBay to try to find an exhaust......
