Has anyone out there ever put anything other than the Rotax 582 or 670 in their kitfox as far as 2 strokes go? I have often wondered with all the rotax engines that are out there for jet ski's that produce 110HP if anyone has ever used any of them. I know that the 582 is dual ignition and produces around 60HP. I am looking for something in the 2 stroke that produces 80-100HP. Any thoughts?
