Default What size pilot and main jets for rejetting 07 TTR 50?

What size main and pilot jets should I purchase for rejetting my 2007 TTR50? Should I change both the main and the pilot? It runs very lean (stock) here @ 3900 ft above sea level. We live in the Mojave Desert. Anyone experienced in rejetting this bike?

at 3900ft its gonna be RICH( to much gas ) so you will need to re-adjust all 3 circuits on the carb

PILOT
NEEDLE
MAIN

all will need to go leaner (less fuel)

in your case its a FUEL SCREW .. turning it out ADDS fuel, turning it in STOPS fuel....(not a 100% stoppage) since the pilots to big the screws not gonna help cause its still flowing to much fuel even when closed...
