Anyone have any tricks on compressing the rings into the cylinder. I tried using aluminum flashing but it didn’t work, cracked the sleeve. When I get the new one, is there a trick to this. I bought a 4in ting compressor but I don’t see had I would be able to use it. I bent the oil rings a couple times doing this because of the taper at the end of the sleeve. Also it’s a stock 85mm bore.
