Pilot jets are there to allow a balance amount of fuel (not air) into the carbs. They are ther for idling and up to about 3-5k rpm on most carb b ikes........full throttle is taken care of by the main jets. Think of a 16valve petrol car, half the valves are for low revs the other half is high revs. Two turns = 2 x 360 deg.
Those are my principles...if you don't like them I have others.
