After Lifting The Needle..still Wrong?

Banchetta, actually the 2.5 turns out was for a warmer setting and air box lid on. I just fired her up the other day after rejetting the mains for removing the air box lid and also needing to add a size for colder temps and it ran so good enough with the same pilot settings that I didn't mess with the air screws. After it was wamed up it idled at about the same rpm but just barely noticeabley quieter. Under the circumstances I expected to need to turn the air screws in due to a colder weather and air box lid off and actually it would probably still benifit from a half to 1 turn in but I just neglected to do it because it ran fine so why mess with it. I can't immagine the throttle response being any better, it's damb good now. It starts first kick every time even when hot or cold. I also think that a bigger pilot jet is better for low end performance, although this may just be my opinion. Fuel is much much less compressable when compaired to air, therfore it is much easier to restrict the fuel than air. When your between1/8 to 1/4 throttle with the engine under load or slightly more throttle but at low rpms trying to somewhat lug the motor rather than down shifting I think that the dymanic affects of the air will allow more fuel to flow in with a bigger pilot even though you can theoretically just about even out a larger pilot with a size smaller using the air screws at an idle. FMF recommends the #30 pilot for all of their pipes and i agree with them.
