Default 89 PRO V 150 carb. help please

I have only been getting 5200 to 5300 RPM at full throtle I use to get 5500 to 5700. So I checked the air adjustment screw on all the carbs. 4 carbs were adjusted 1.5 turns out. One side of the middle carb was just over 2 and the other side was 1/2 turn out. What would be a good starting point to readjust? I assume 1.5 turns off seat, but seeing how I have never adjusted the carbs on this motor and it seemed to have moved on it's own over time I really would I like a good safe starting point. Any suggestion would be appreciated.
