I would try re-adjusting the idle using the highest RPM method again. I've found that minor adjustments to those mix screws make big differences in how the bike starts, idles & takes off.
Two turns out sounds a bit lean to me - warm the bike up, adjust the idle to around 1200, put a fan in front on it & systematically adjust each mixture screw until the engine RPM is at it's highest. You kinda have to listen & "feel" the bike vibration as you do it.
Blip the throttle & see if it's getting smoother, reset the idle back to 1200 and move the the next carb. I do the inside ones first (2 & 3).
When done right you should hear the exhaust go from a kinda "tinny" sound, to more of a lower rumble (relatively speaking). Also, when you blip the throttle it shouldn't bog or hang at the higher RPM's.
THEN do your carb sync & see if it's better... might want to raise the needles too, to eliminate any mid-range flat spot.
good luck
