sleeper06 Posted November 17, 2014 Report Share Posted November 17, 2014 Post pics could be 1mm over or something else plus before ordering anything someone should bor guage those cylinders so you know if it's outta round or a quick hone might suffice Quote Link to comment Share on other sites More sharing options...

tfaith08 Posted November 17, 2014 Report Share Posted November 17, 2014 Send it to a reputable builder. They can gauge the bore, order the pistons, bore the cylinder to the pistons, chamfer the ports, and hone the cylinder correctly. Anyone who doesn't specialize in 2-strokes is likely to screw you up, whether intentional or not. Quote Link to comment Share on other sites More sharing options...
