Howdy Guys, Just another new guy who wants to jump in the pool. Picked up an '04 WR450 about a year ago, not to long after finding this site and forum. You guys helped me decide to get the WR. Loads of good stuff here. Have done some of the mods.... Air box, Pro Moto Billet insert, YZ throttle stop(that made a differance) and James Dean jet kit in the mail. Not sure I want to do the gray wire. Help much? Did start having a problem this spring. Have what I call an of idle bog. I let the motor rev down, then wack it, it bogs. Hope the JD kit will help. Could it be a Pilot jet? Does not do it all the time. Will do more research. Looking forword to Yak'n with you guys. Thanks in advance for all the info I'll glean from this forum.
