5300 ft alt jetting

[Cole Trane]

I ride a 2002 400ex with a powercore 4 fmf slip on. I was just hoping someone could give me an accurate jetting for the conditions I'm in. I ride in Albuquerque, NM at 5300 ft altitude. Right now I have a 142 main jet installed, and stock pilot and needle setting. If anyone can help I would appreciate it.

when you go higher in altidude doesnt it become richer?

400exrider I am from Albuquerque also and have jetted a few bikes here and i use to have a 440EX but sold it to get my raptor. When my bike just had a slip and K&N filter with no lid I ran a 152 main, needle 3rd and air screw 2/5 out.

I have not heard anything about it, where is it at? If you let me know, maybe I'll show. Anyway, thanks for the info! Let me know about the race, and maybe we can meet up. If not there maybe somewhere else, like montesa or something.
