Piston Rings

Well first you should get the cylinder off and see if there is any damage to the piston and the cylinder. Than go from there....
 
I know a mechanic fairly well, but I'm no exception to any other customer. =P
I'm fine with it, at least he knows what hes doing.

I don't know if it has to be bored or honed yet, hes still working on it. I hope its just rings.
