you guys have no idea of the carnage. When I took the engine out of the bike the rod was pinned against the front motor mount bolt. and when you looked straight at the cylinder there was a 3" hole clear through to the other side. I think what happened was the piston siezed which broke the rod and sent it into the motor mount. and the force just exploded the engine. I went out to that same area the other day and found where it happened. there were pieces of my bike all over the ground and a trail of oil and skid marks on the pavement for 300 feet! Definately an experience, to say the least.
