Normally, the screw is about 1.5 to 2 turns out, but it does depend on the pilot jet. If the pilot is too small or too big, this screw could be way in or way out.

Normally it is about 1.5 turns out.

With the bike hot and idling, run the screw in until the motor starts to idle down, then slowly turn it out until the motor reaches it's highest, smooth idle. Reset your idle speed and you are done.

If the screw ends up being turned out more than about 2.5 turns, your pilot jet needs to be smaller. If it is turned in less than 1 turn, you need a bigger pilot jet. This assumes the screw is behind the slide in the airstream. If it is ahead of the slide, then all this talk about the number of turns is exactly backwards.
