wr 426 power mods

Recommended Posts

I picked up the first wr 426 in Washington, but I've only gotten a couple rides on it. For those of you who think this bike is fast, try removing that interesting little silencer insert (1 screw on end of pipe) and back the throttle stop screw out. Unlike last year, you DO NOT have to disassemble the carb to do this. The screw limits the throttle to half of wide open. I backed mine out to three quarters of wide open, and it's already a different animal. I tried to get a YZ stop screw (I assume it does not limit the throttle), but none are available yet. I will trim the one I have before the next ride.
