I did a compression test on my 95 Seadoo gtx 657x, and find the front cylinder has lower compression than the back 80/130. I added a little oil thru the sparkplug hole, restested and the front pressure went back up and both were about even, after a few day I did another compression and the front was back down to 80 again, so after pulling the head off, I find the piston ring is broke, can someone please tell me how to go about changing the piston rings? Can I take the one cylinder case out? I need all the help I can get. Thanks.
