The gen2 bandit(01-06) has the idle adjust screw on carb number 1. When you're sitting on the bike turning it towards the rear of the bike increases idle rpm(clockwise). I believe the gen 1 carbs (RF900 carbs) have the throttle stop betweem 2 and 3 which would mean you turn clockwise or to the right of the bike to increase idle rpm. Of course the other way will reduce it.
