2 turns has always given me the best idle. Maybe a quarter turn in either direction for the major temp change from spring through winter. Really steady.
*UPDATE
After my first real ride into work - bike is running great. Really smooth. I feel like I've had a HP or two more before but who knows.
My idle IS steady, but its running high and the idle adjust screw isn't winding it down at all so I may need to dial in my air screw a touch.
