Try turning the air screws in and see if it gets worse or better. I bet its a bit to rich you might end up droping the needles 1 clip. Try the air screws first.

Try the air screws first. If the midrange is fine you dont drop the needles to fix a problem off idle. What size of pilot jet do you have in your Keihin's? Keihin should buy the rights to this write up and include it in the box with their carbs. It is that good.
