I have a 2002 WR426, I have adder a FMF Q pipe and cut the throttle stop removed the airbox lid,and cut the gray wire. I have been trying to get the jetting correct. I went to 45 on the PJ and have tried several different main's. The bike runs good at low end but runs crappy at high RPM,s. Has anyone out there jetted a WR and if so what are you running.
