2.5 turns out is usually pretty close.
I would sync the carbs before doing any fine tuning.
As far as fine tuning of the Idle Mixture (on any engine), I like to find the setting that produces the highest RPMs - then go just slightly richer (about 1/8 turn OUT for the Ninja's carbs). Then set the idle speed. The engine should be fully warm when you make the adjustments.
That shouldn't change the RPMs much at all, but gives you a smoother transition as you open the throttle.
As temps change you may need to make slight adjustments. Colder air requires more fuel (out).
