Re: Sprocket Installation - Bicycle Engine Kit i would wait to see what chris says. i just know what i saw at the bike shop and that was a destroyed wheel with only one doghnut on it. i would think but i could be wrong metal on metal with vibration and contant tugging the metals will be rubbing which cannot be good but as i said i would see what chris or andy or mike has to say since they have both built lots of motorbicycles |
