You don't want to remove the throttle stop, just grind it down about 18mm. As for the exhaust, pull out the innards "uncorking" it, and then buy a promoto billet endcap and spark arrestor so your are legal and less noisy. I think you can search this site for the other free mods including the gray wire and such.

head over to the WR/YZ250F FAQ, there are a lot of hints and tips there that are also applicable to your WR426F as well.
at the least you can use the pictures there to figure out where the throttle stop is.
also see my page here:
note that the 250F and 426F probably have different throttle stop lengths -- but you can figure out how long yours needs to be by looking at the slide open through the carb intake.
