I have posted a photo of the pin that sheared. Its the intake timing gear and cam shear pin. The one that keeps things intime. tried to drill, too hard for my drills. called a machine shop, and when they heard motorcycle, they said they could not help me. How do I get this broken half out of the cam ? Tried to drive it through, it does not move. can't get to the back side to drive out. any ideas ?
