I had the same puzzle when I first picked up my '03 KX125. You can't just twist a knob like on most modern bikes - it's a small brass screw (for a phillips head driver) and a locknut on the left side of the carb. You might have to push an overflow hose to the side before you'll spot it.

Oooopps...that was the idle screw in the other post. The air screw is on the same side (left side when sitting on bike) next to the air boot and behind the carb fuel inlet. It's a flathead screw.
