I have an 02 WR 426. I've done all the free mods except for the yz timing (which I plan to do). I have the yz throttle stop, a twin air air filter, a gytr ehaust insert, and the grey wire is no longer. I ride anywhere from sea level to 4,000 ft. with the temperatures ranging from 40-95. Does anyone know what size jets and what clip position would be the best?

Go to the sticky thread at the beginning on this section. Once you open it search the thread for wr426. :)
