2004 Ninja 250 air fuel screw question

I have a 2004 Ninja 250 with 8k miles. Carbs were ultra sonic cleaned and rebuilt using All Balls kit. Set the air fuel screw at 2 turns out. Float height was set wet level with the fuel bowl mating surface of the carb body. Sync'd carbs. New NGK Iridium IX Spark Plugs CR8HIX. Adjusted valves. I feel like there is a "dead" spot at 1/4 -1/2 throttle at constant speeds. I read other forums saying this bike was lean from factory and some recommend 2.5 turns out. Would having the air fuel screw 2.5 turns out help this issue?
