Help! I just pulled my 53 out of 24 year storage. Found that a mouse went up the tailpipe and found the #1 piston at the begining of it's exhaust stroke. That left the piston towards the bottom of the cylinder and the exhaust valve open. Mickey made a nice home in the cylinder and did his duty within. The urine ate a hole through the top of the piston and right through the side of the cylinder wall! The motor is in the machine shop to be sleeved as it was a 50k motor. My dilemma is I now need a standard bore piston. Any one have a lead on a NOS or good used one? Thanks. Mike #5142 (I think!)
