If your engine suffers from a scored cylinder and is suffering from low compression you may look at reboring the engine and while you are at it you may just as well bore it out to a greater capacity and fit newer cylinders. Check the end gap by placing the ring into the cylinder. Post by brb86 » Sun Nov 10, 2013 6:13 pm Hi New to the forum and an ST70.
