Default Glowing Pipe

So I'm looking at picking up an 07 and the owner said it has one issue, one(just one) of the header pipes glow red after the bike has been running for a bit. He said he flushed the coolant and checked the thermostat but it's still glowing. I did some reading on here and it appears this is fairly normal as long as it doesn't go past the bend. Anyone have any advice on this? If there is something wrong, what type of stuff should I look for when I'm checking it out tomorrow? What's the worst it could be? Thanks for any help!

Whats done to the bike, may be running lean. Mine glows a bit but not a lot. My 450 on the other hand will get bright red up to the bend

As far as I know, nothing that should cause the glowing. Here is the ad:

I've never owned a bike that the header glows red during the day in the light, even with aftermarket pipes. However, they ALL glow red at night, this is quite normal. If it is glowing really red during the day I would think its lean. Did he just get a new air filter, or did he get an aftermarket intake and possibly pull the lid on the airbox, maybe pull the baffle on the exhaust, resulting in an overly lean condition without a fuel controller causing a more noticeable glow?

Like everyone else said, a little glow is normal, but if you think its excessive, here's a couple things to check/think about.

1) He mentioned a new spark plug. Did he put the correct one in? If he for some reason replaced it with a hotter heat range plug by accident, it would cause the cylinder temp. to go up.

2) What kind of fuel was he using? Maybe he was using regular instead of premium. I'm actually not sure what's required, but I've always used premium regardless.

3) The new air filter. Is it stock or did he change to something that flows better? This would make it run lean.

Don't know if this will help or not, but its just a few things I can think of that's easy to check.

Just like the bumper stickers, and t-shirts say "Ride it like you stole it!"

Glad she turned out to be a nice riding machine. Be safe, and have fun!!

WOW! you don't hear of that happening to often, when you put the new one on you might want to make sure that it's routed correctly and lube everything real good. also there is a wide open stop that needs to be adjusted properly or you can damage the throttle body and break the cable when the throttle body goes to it's limit before the lever hits the stop. Alot of people think it's just a throttle limiter for beginers so they just unscrew it all the way out. It's also a stop for wide open throttle. Good luck with your new toy, ride safe and WELCOME to the forum
