2002 Cr80 Expert

MB7, I've raced since I was even able to walk. Been building and working on motocross bikes for several years, and your "statement" has brought me to ask this question. lol Where do you get an expansion chamber out of a cr80? A cr80 is an internal combustion nonvalve 2-stroke motor, that is capable of producing some power. But no expansion chamber? If your talking about the exhaust system, yes that is aftermarket, and it's very highdollar. Nice looking bike terry.
