    Does anyone know what the adjustment screw in the middle of the carbs on the back side is for on a 2kr, right between 1,2 and 3,4 facing the rear of the bike

    Welcome to the forum

    Which adjustment screw are you talking about?

    Idle speed screw

    These would be the sync screw's, there is also one between carb's 2 and 3

    And the mixture screw's are on the opposite side of the carby's just below the diaphram cover's in each carby body
