Started cleaning the carbs but need to know how many turns out (from completely tightened) for the standard setting, then i can work from there and set it to my requirements.

cheers
Adjusting the idle mixture screws is a bit tricky. Ideally you should set them at 2.5 turn out from closed position and then readjust while the bike is running with a vacuum gauge hooked up. Typically you would just turn in the mixture screws until it stumbles, then turn out the screws until you reach maximum vacuum. Make sure you get a very short skinny screwdriver to reach the idle mixture screws though.
