just picked up a 74 750. It starts up first kick, revs fine until 5500 or so, then it sucks. Bogs, pops, doesn't go. Until then it's great. It has pod filters but I'm going back to the stock air box when I can find one. Carbs are real clean. With a 4-1 header, no baffle, and stick air box, what should jetting be? Air screw settings? Im hoping once I go back to that and get the carbs synced it should be good.
