there is big bore kits, cams, probably even stroker kits to really get some power out the motor. but most would opt to not go this route because it might lessen the dependability of the quad.
i saw a video the other day of a polaris (yea i know boo!!!) 700 4x4 racing a Suzuki 400 sport 4 wheeler and the polaris draged it.
the thing about a utilty quad if you make it real fast is its higher center of gravity is going to make it more unstable. im going for the same thing with my 300 fourtrax, so i understand where your coming from.
