That is a 2 stroke! Freshen the rings at least at 3500! Pistons too likly by 4500!
You guys that think compression readings are all that are needed to determine if a topend rebuild is needed crack me up. The only true way to determine what is needed for a topend rebuild is to measure the piston to cylinder wall clearance. Many, many engines have had excellent compression and ran just fine up to the point where they break a skirt off due to excessive clearance. I see this every day, shattered pistons and broken cases come through my door at a steady pace. And I'm not a dealer mechanic- no dealer is willing to pay me enough. As usual KC Cats is providing good advice.
