The 1000cc motorcycle motor isn't any larger than the 600cc motor is externally so why not just go with 1000cc motors and spice things up a bit? Both motors are a lot smaller and lighter than the Honda 750. While 600 cc motors have large numbers of motors out there in the market place they also have 1000's of sidewinder racers that also want to buy these same motors. A 1000cc TQ would be a real Rocket Ship, and probably cheaper in the long run than a 600 motor with lots of mods done to it!!!
