    x motor has a belt driven alternator, charges much better, uses motorola electronics instead of merc(better idle and all around running), x motor uses a downdraft style throttle body/plenum w/ the injs inside the plenum, flows better. x motor has no stator or trigger and also uses an o ring style head. just newer technology
