Can someone help me out on how to increase the compression? I know 2 strokes cant have high comp pistons because of the ports, so how does one make their blaster high compression? I want the max that i can still run 93 octane pump fuel. I read on google of getting some of the head shaved off/milled. How expensive is this? And can someone give me links who can do this and or more info on what im trying to do?
