Not a mini bike but, for the Predator fans here, I'm throwing a new Predator 420cc and Comet torque converter in this kart and doing some frame work fab. What do you guys think about the 420's? I took off a 6hp Mitsubishi. Should this kart really scoot along now? I wasn't able to drive it before because the torque converter was toasted. Never had any experience with the 420's before. I know gearing changes might need to happen also.
