WAYNE - you are confusing two different things - each carb has a PILOT JET and a PILOT SCREW (sometimes called 'fuel screw'). The pilot jet controls how much fuel gets to the engine during idle and up to about 1/4 throttle. The pilot jet will have a number (probably 22.5 or close to it) on it. The pilot screw acts like a valve to adjust this fuel from the pilot jet - the jet controls the max flow, the screw just can turn flow down.
The carb also has NEEDLE jets and MAIN jets - the needle jets control fuel flow from about 1/4 to about 3/4 throttle and get moved up and down in their bore (adjusting fuel flow dynamically) by vacuum from in front of the butterfly. Main jets control flow from about 3/4 to full throttle - mains will have numbers somewhere between 140 and 170, if they are typical Mikuni brand.
So with this info in hand, what is your question now, Wayne?
Travis - this is your 3rd post on the same issue - the moderator is gonna get mad at you!
