I have a 02 WR 426, i have always had a small dead spot from idle. If i am at idle and crack the throttle fast it wants to stall. also at 1/2 throttle it has a sputter. My jetting is, Pilot#42 Main#168 Starter#65 Needle is at #3 Screw out 1 3/4 turns I am going to set needle at #4 and main up to 170. Am i going the right way? I am at 1300 ft and usually ride when its between 30 and 80 degrees.
