This is a set of four mounting bolts for the Baja MB200 plastic shroud pull start Note these bolts are longer than the three mounting bolts used on the older model MB165 pull start This is a set of four mounting bolts for the Baja MB200 plastic shroud pull start. Note these bolts are longer than the three mounting bolts used on the older model MB165 pull start. These longer bolts will work on either the plastic shroud MB200 mini bike pull start or the older MB165 version. But not vice versa — the MB200 needs the longer bolts.
