Hey I'm doing a top end on my 88 yz80, the cylinder walls are in good condition and still have a cross hatch pattern on them, but I have low compression and just replaced the ring (one ring piston). The piston has blowby and the ring was installed properly, this just means time for a new piston and ring right? No replating or boring necessary?
