jetting WR426 the never ending topic help J.D.

Recommended Posts

I have setup my bike with the following jetting. I however have not had a good day to ride and would like to know if I am wasting my time..

I have setup

175 main jet

45 slow jet

200 main air jet

EKN needle 4th clip

Air box top removed

Baja designs Vortip in exhaust.

o-2000 foot above sea level

wr timing

I understand I will never get to the "disable the accel pump" level but am looking for the best simple jetting. Because I will probably never be a racer.

Comments are appreciated (even abusive ones) :)

Thanks Andrew

Andrew,

Try a smaller main jet - #168 and 1 1/2 - 2 1/4 turns out on the pilot (fuel) screw.

This is close to the '01YZ426/YZ&WR250F jetting.

If you have any specific problems feel free to ask. :)

James
