Thanks for the reply, Duckndive.
the main jet is not my main concern as that can be finalised on the dyno (i.e. goin fast!). My biggest issue is from tickover upwards. The current 'standard' setup (as listed in my OP) doesn't have the motor reving nicely hence my post. Because I live right next to what appears to be the entire elderly population of my home town, Its not really possible to keep swapping/adjusting then running the motor up to temp to test. I'm after an approx baseline for pilot jet and needle size/position so it runs 'reasonably' well so I can get out of town for any fine fettling/plug chop - before dyno visit (60 miles away). Btw, my blower is a T3/T4 hybrid (not that really matters here).
Thanks again for the info. I'm kinda hoping someone on this forum has that same carb as me on the same gsxr/busa/garrett on a draw-thru setup.
