YZ timing

4 posts in this topic

I am looking for some feed back on the YZ timing mod for a WR426. I am thinking about doing the mod but do not want to give up low end. I am also looking for jetting tips for low altitude. I have done the gray wire mod removed the air box lid, installed the YZ throttle stop, and put an FMF Q exhaust on the bike. Any help is appreciated.
