as far as the ring gap, the ring is iron, the piston and cylinder are aluminum, the aluminum will expand a lot more and faster than the iron ring will, so a small gap shouldn't hurt anything.
I agree 100% on that. I talked with Frank Bowman and he said he never had any problems with a .001 inch gap. If your engine has only one piston ring...it is important to not let compression escape with a ring end gap that is to big. The aluminum cyl is going to expand moe than the piston ring....increasing the gap. Capt,n
