PWK 39 168 Main 58 Pilot #7 Slide cut-away N82M Needle Air screw 2 turns out 15-17mm float height
There was no clip position in the book, the '99 is the same needle it is 3rd clip position
We ride from 3500-6000 ft. I know every bike is different, our kx 500's have a pc pipe, I have rad valve his is stock reed. Mike and I are happy with this, #7 slide, 2nd needle clip (n82m) a 158 Main #55 pilot and 11\2 (or so) air screw.
Mike puts a larger main (170) in when he goes to Oregon dunes , and lowers clip, how far depends on weather.
I run Blue Marble 50:1 ngk heat range 7 Mike runs Maxima 927 40:1 ngk heat range 8 (he rides alot harder than I do)
