Have you shimmed the needles?
The carbs are usually lean in the mid-range, and shimming the needles richens it up and smooths-out that area. The Main Jet is typically plenty rich.
As ducatiman noted, take some time and get your idle mixture screw adjusted precisely. Make sure the engine is fully warm and the gas is fresh. That adjustment will change with weather, so know that you may need to make additional adjustments if the temp changes significantly.
Make sure your air filter is clean - and not over-oiled. Carbs synced and valves adjusted as well.
