Actually if I were to buy a second quad I would buy a used 650 brute in decent shape and stick the money I saved buying used into motor work. Those Kawi's have so much more aftermarket support because of the potential of the motors. I can't remember the exact numbers but you can stay at 633cc's and bump up the compression and change cams and get somewhere around 70-90 hp depending on your setup with the help of Fundy. Fundy is supposed to be working on an engine kit for the Kingquad, crossing my fingers here.
