Adjustable jog 90 pulley kit! These will fit your zuma, but you need to clearance the case, and they act as a budget overrange, if you run a longer belt and front pulley. This is selling for dirt cheap, as we do not have the time to invest into finding the right belt fitment etc. PLEASE only purchase this if you choose to do your homework, We do not offer any technical support/advice on this item.
