The little gremlins that plague my cannondale have taken over my electrical system. I'm thinking of pulling out my cannondale motor and swapping in a 310r or a crf450. I'm not sure if I want to keep it a 4 stroke or go for an extremely fast port/polish 310r. Has anyone ever heard of a 250r motor swapped into a cannondale frame? I am told that the 450 swap can be done pretty easily but I haven't ever heard about a 250r motor. The motocross racers usually run a 250r or a crf450 in the same frames right?

He put a YZ426 motor in a Cdale frame and shaved a lot of weight - could probably help you with your ideas.
