You need to use an allen bolt or something that will loosen the end of the grips i think its an 12 or 14mm? but i could be wrong but its a big size though.... once you loosen the ends the whole **** chrome end piece of the grips will unscrew... its one whole big piece... the rubbers of the grips would need to be peeled of or use a razor and cut it carefully on the throttle side making sure that you dont cut into the throttle tube
