Recieved a "free" 2003 renegade 600 ho from the father in law. Mint shape but compression was low. 75/100. Did rebuild with wiseco kit. Did compression test cold after re-assembly. Getting 60/125. When dropping left cylinder on, ring pushed out a bit and slightly bent down a bit. So I took it off and just with my hand I straightened it. Put it back on and put cylinder on. Not sure why I thought it was a good idea to continue. Anyway can we agree that the ring is likely the cause of the low reading?
