Just wondering if the grey wire, throttle stop, air box mods, etc. will work on my '01 WR426F? I have searched and haven't found any info on the free mods for a WR426 instead of the WR450. Thanks.

Yup...grey wire, YZ ( or cut) throttle stop, remove the snorkel, and unplug the exhaust...the exhaust is far easier on the 426's, too! You will be amazed at the difference. Try YZ cam timing as well if you're not going to install an auto decomp cam.

birdy's right
here is wr 400 info on yz timing
i believe that the 426 is closer related to 400 than 450
good luck
