ok, got the top end put back together with a new head gasket and some fresh rings,, but i  suppose that didnt to the trick, it seems its infact time to bore it. Ive still got terrible compression and am burning oil in a real bad way. My plan is to send the jug to a shop to bore it out but i dont really know where to get the proper piston, id like to go with a 96mm if i could find one at a good price
