Can anyone confirm if this carb's (82 GPz750) pilot air mix screw richens the mixture by turning the screw IN. I've made this assumption in trying to resolve popping when rolling off the throttle (I've added a 4into1 pipe with everything else stock). Going 1/2 turn IN (richer has not improved the situation and may actually be slightly worse. Any suggestions as to where the pilot screw should be set? I also went two steps richer on the mains (115's) and one clip position richer on the needle (needle position #4).

Thanks
Garry
