I know it's probably been beaten to death and I looked at the jetting sticky but still had 1 question. I race a '94 kx500 supermoto and motor wise it's set up with a fmf pipe/silencer, rad intake and a steel liner with a 1 over piston. I usually run it at right about 2200ft but this weekend will be heading over to seattle for a race and they are at sea level and won't really have any set up time. I'm also running a 50/50 mix of trick leaded 114 and 92 mixed with 927 at 32:1.
Right now I'm running 1 clip from the leanest, 160 main and a stock pilot which I believe was a 50. It runs pretty d**n hard right now but could use a little more fuel on top and I'm afraid if I drop 2,000 ft it could get a little lean
I was thinkin just getting a bigger main, I got a 165 but do you think that would do it or should I try a 170?
Any help would be greatly appreciated
