N3CW pulls good from bottom,but only with 45 pilot and 178 main, if I go down on pilot ,quick acceleration will result in BOO AAAA! In teory witch needle will give max torqe and witch one will give best consumption?

I had the same question with my 250R (ASII). Currently it has 182 main, 42 pilot, N3CJ on third clip and 7. slide (stock). It feels a bit rich around idle and very low RPM's when it's hot (over 25C) and I'm riding slow difficult track, so I have to turn out the air screw more. The dealer told me that if anything, he would go to slide no6. I'm quite happy with it, it has good torque and it's quite economic too, about 150km of easy riding before having to turn to reserve or 120km harder trails.
