[QUOTE="RossKean, post: 1063897, member: 19880"] If it is just the head (and that's a BIG IF), could a donor head fix it up? i.e. The head from Patriot's motor? Replacement piston. I guess maybe a con rod too. If the crank is damaged, then all of the above has been a waste of time and parts. This is already getting complicated with a lot of labor and no assurance of success. If metal bits made it down to the lower parts of the engine, who knows what damage might have occurred. I agree with Ionbeam - starting to smell a little like bread under a grill. Get a used low-miles engine or part out the bike carcass to help offset the cost of a new MC. [/QUOTE]
