ok i bought this sled just the other day and only put 6 miles on it total and then the right piston blew out the outer edge basicly is gone on about an inch of the piston, the cylinder is fine and there isnt any scratch's on side of piston, so my ??? is how do i make sure the bottom end is free of shavings or chunks ide like to keep the motor in the sled any ideas???
To be sure you would have to split the case and clean it out to be sure, but if it lost as much as you said it lost I think you run the risk of further damage to the new piston if you dont get everything out.
