yeah, i haven't played with that yet.. i did take it apart and only thing i found wrong were the floats were bout .200 too low and some gunk on a metering rod making it stick.. purrs along fine though, the 4.57 makes that little motor a bit of fun :) Not beating it bad til i figure out the brake **** or go back to drums. I don't trust the discs at all but am waiting til i break in the pads to be be sure
