Well we put the basically stock pitster motor against a built apex and a couple of takegawa motors.. Ran with them just didn't have the top end the others had. Those were built motors tho. Rage built one , Scott built one the apex was a BHR motor... It didn't do to bad.

Only mods on the pitster were carb and gearing..... Remeber I have a pitster motor on a honda 90 with robbs suspension.

I am getting another motor and sending it to Rage ATV to give it some rage power. Its definitely going to make power..
