It also helps to state your motor and scooter model but i guessed 139qmb cause you said 100cc bbk and the tooth count on the oil pump you need to know before ordering a new one some name brand ones half way down http://www.racingplanetusa.com/engine-performance-parts-c-27987_28573_28591-1.html?sessID=56fd126c3415114c468b620f90ea40b2
