Greetings gents, finally got off a CR500 and bought a WR426. What was I waiting for? Quick question, I heard of a cam timing change you can make to the WR426 to bring it to YZ specs. Anyone have a websit or info I can go to? This bike is completely stock, even has the exhaust insert. Also, just moved from San Diego to Maryland, looking for riding areas.......

Heres a site that shows you how to do it on a 99WR. Im sure it cant be much (if any) different.
scroll down a bit...

Zoomy, Most of the free mods for the WR are right here on TT. First page that pops up when you go to TT, click on Motoman, and check the Tech articles. They have instructions and photo's. Good luck
