For a KDX 220R '99 w/ FMF exhaust Rad Valve and Keihin PWK 35 AS. The carb stock jets are 160main jet, 48pilot jet, 4.5 trothle valve, 48 DEK Jet needle, I feel the settings too rich I move the jet needle clip to position 2 and feels better but without outstanding results. Do you recommend change the main jet to 157 and the clip to 3???
