Well go big, I once read a article in Cycle World few years back about a Polaris engineer that put a twin 700cc Polaris Liberty snowmobile motor into his own frame with al Ducati gearbox. They where very impressed with the test ride. The motor was turn around with intakes in front and exhaust straight out the back, looked very cool. Ski Doo just came out with a FI twin 1000cc, that would be mine ! Still a 2 stroke, bing bing !!!!!
