I built a kart based on a Kettler pedal car. I am thinking of switching my motor to the Razor Ground Force. Can someone tell me:
a)What is the stock gear ratio on a Razor Ground Force?
b)What is the shaft diameter?
I would probably try to mount one of my metric sprockets on the Razor motor, since i can't chance the sprocket on the drive shaft.
ps - photo attached. Body almost done Bondo-ing.
