For sizing, you’ll have to measure whatever cable stop you’re trying to replace. Then go to treatland and search ”knarp” and find the closest to that size. For the throttle you will need to replace the stop that is on the side of the cable that is closest to your hand. It’s a really small knarp. If your cables are shot you might as well replace all of them. Treatland sells E50 and ZA50 cable sets just for the Maxi that come with all the knarps you’d ever need.
