My '06 KX250 is still running really rich. I have the clip raised all the way. 50 pilot, NFTG needle, 160 main. I'll be installing a smaller pilot and see if that cleans things up (right now the air screw is 3 turns out). If I should need a leaner needle, anyone have a recommendation? Looking for something not only to lean out the midrange, but to provide more linear power.
