    the sequence is very important. start with carb that the idle adjustment screw controls.

    if the carbs are mounted you will need a proper set of gauges; if off the bike you do a bench synch.

    match the vacuum on the front 2 cylinders, then match the 2 rears together, then work on the f/r linkage screw to balance fronts to rears. there is some interaction between screw settings so it takes awhile to get it right.

    snap the throttle a couple times anytime you move a screw so things settle into place.
