The air screw is set to riding conditions and is adjusted at least once every ride. Well, I know a lot don't do it but you are supposed to for best throttle response. You normally want to be about 1.5 turns out as a general guide.
Does your have a PWK carb? Check to make sure your float isn't adjusted too high, that the jet block gasket isn't leaking, that the jets are clean and genuine OEM brand, and that the hole the needle slides through is perfectly round and not slightly oblong. If it's the original carb it's possible it's just worn out.
