Thanks in advance.

Just picked up my WR450F today. The only "mod" performed so far was taking the silencer out of the exhaust. Once started, the bike idles ok then eraticly begins to idle. I'm discouraged but I know I'm going to love this bike once I resolve this eratic idling issue !
Thanks in advance.
Did you try putting the silencer back in to see what happens? Did you try adjusting the idle up and down? I'd try these since they're easy and can narrow it down to either jetting or a problem with the float.

Argh.. I'm frustrated.. I just don't understand this.. I'm told that when the dealers put these bikes together they don't touch the carbs.. just uncrate the bike, put the front wheel on and fill it with fluids (oil/coolant/fuel). I guess I'll call the dealer and try and uncover some information as to how they set it up.
Without leading anyones thoughts, it seemed as if the eratic idle / rev's started to appear after the bike was completely warm (5 minutes or so).

Don't feel alone, I also just got an '05 wr450 (Ca. model) and it is doing the exact same thing as yours. I took it out for the first time yesterday
to break it in. I have not done any mods at all yet. It seems to be more of the slide not fully closeing to me than jetting or an air leek causing it to lean out. I'm not too worried about it. I am planing on doing the free mods this week along with jetting and will have a close look at the carb I'll let you know what I find as soon as I get done.

Appreciate the response, not that I'm glad your bike is doing the same thing but it is somewhat comforting to hear that I'm not the only one. I spoke with the dealer down south this morning who stated he would have the service manager contact me tomorrow morning and work to identify the exact issue. The guys there seem honest and sincere and stated they would send (for free) any parts I needed.
Really looking forward to what you find for resolution on this issue.
Just for my own info, is it doing it without touching the throttle (i.e., start the bike, let it idle and it idles up... ) or does it only do it when you deccelerate? or both?

To answer your question the idle hangs up on deceleration almost everytime unless the throtle is bliped, set idleing alone I've only noticed it
creap up once. Keep in mind I've only warmed the bike up a couple of times. I've allready got the lowedog ais kit so I'll make that my first mod tuesday nite and post the results here. I bet you'll have it all figured out before I even get mine up on the bike stand, so don't stress about it too much I've
got a feeling I'm really going to like this bike once I've got it all set up.

mine done the same did all the free mods not sure what one fixed the problem but 1 of em sure did.. it is one hell of a fast bike now.. no problems at all
I would second that. I had the same problem with my new bike - it idled worth a crap. The first thing I did to the bike was re-jet with the JD Jet kit, and the problem went away.

I am assuming that your boot is not leaking on intake.

No more eratic idle on my bike. I first did the ais removal mod from Lowedog, started the bike and it still idled like crap but did NOT HANG UP
as it did before. Next I went with the jd kit, removed snorkel,back fire screen and pea shooter mufler end. Thats all it took and the bike is good to go. Let me know how it works out for you, I will be out in your neck of the woods some time mid march so if you don't get it sorted out I'll see if I can help you out. You'll get it though, even if it idled correct you would still want the mods to make the bike all it is meant to be.
Good luck and keep me posted.

What jetting did you go with? I'm doing Lowedog kit, JD kit, Zipty fuel screw, & YZ pipe this weekend. I'm having the same problem. I'm thinking 170mj, 48pj, & 70sj.
