Review star X 155 of motorstar 10th avenue caloocan

wheel sprocket of star X 155 does not match to other motorcycle , They dont have ample stocks for this parts especially when you are going to upgradeb the speed . i am looking for a wheel sprocket with 38 teeth but no to avail on their spare parts center in 10th ave . How much more if you have a unit and you are from the hinter part of the phillipines are you going to acquire a unit without spre parts ?
