Glowing orange header

Hey, anyone having the same problem I have. I just got a new 05 Wr450FT and am in the process of breaking it in. The header glows orange after about 10-15 min. of easy riding. I have removed the AIS and have rejetted it to a #170 main blue needle 4th clip and still it runs hot. Will this condition fade as I break it in longer. By the way I am running 92 octane pump gas. Will 95 + help this at all? :naughty:

Ride your bike at night and watch the header pipe turn bright orange :naughty: It's totally normal and no need to worry about it

i have the same bike. the guy at the dealer told me it was gonna happin. doing the exhaust mod helps abit. and if it realy bothers you kick it into fifth and cruise at low rpms.

Yep, mine glows too. '02 WR. Think of it as an additional safety feature that makes you more visible at night. It also doubles well as a cigarette lighter when your matches or lighter get too wet from riding in the rain! :naughty:

its kind of a pain in wet riding i rode through a creek the other day and was blinded in a cloud of steam.

My 05 is over the 450 mile mark and there is much less glow. Almost like the metal has tempered. You should notice the diff as well.

Normal! Just dont dump it in tall dry grass! :naughty:

Mine also glows bright red. I'm just lucky you asked the question before I did. I logged on to ask and now have the answer. Thanks All.

It is probably a little bit lean from the factory. It will always glow, but should glow less and later with proper jetting.

And whatever you do don't fall on it, skin graph's are costly!!!! :naughty::naughty:

hehe I think this "feature" of the WR scares all of us when we're new owners.

Now I show it off to friends and family. The glow on the ground when riding at night is cool as hell :naughty:

My buddy just bought a 05 Wr450, and when we got back from our first night ride the header was glowing red which we thought was normal at the time and it was. The next day we went out on another ride for about two hours, and come back to camp for a cold one. As we get off the bikes our friends dog comes over and decides to walk through the front tire and where the exhaust header was. Well to make a long story short I stared to smell something burning and just when I started to say something the dog lets out this big yelp. You can just imagine what that dogs back looked like. Poor guy, he had no idea what he got himself into. Dont worry the dog is ok now but where he was bunred about a 2 inch by 5 inch spot his hair wont come back. A little reminder for him next time i guess.

Will going to a 48 pilot jet help?

It seemed to on my DRZ.

This is a pretty Normal Feature...My '03YZ 450F Did the same thing, I wondered about it then. My '05 WR 450F does it also. (much compression)

Your's hasn't glowed in awhile :naughty::naughty:

The reason the thing glows is because the pipe is single walled. Most streetbikes have double wall headers and typically won't glow. Running lean or rich, it ain't going to matter. Ti pipes are even thinner than stainless and will glow more!

Even my ceramic core Big gun on the drz showed orange in the winter.

Move the clip on the needle to #6 position to help richin things up.

when you change your oil, you have to warm up the bike first right? yeah i did that, and when i bent down to loosen some of the bolts, my knuckle grazed, barely touched the pipe, and it sounded like hamburger meat on a skillet. burned a big patch of skin clean off my knuckle, and that was after just letting it idle for 3 minutes.

I just lost my newbie status with this post! :D:naughty::naughty::D
