The linkage is progressive. The left carb opens about a third before the right one opens. Then they both go WOT at the same time. There is a black plastic link between the two carbs that connectes the throttle linkages. That little piece is 45 bucks. If your missing it, youve gotta buy it. Although I made one out of heavy wire, because I wasnt going to drop that much dough on a bike I got for free (83 XR500).
