I've not seen anything like that either. I have a nine though. Are you done with break in? If so, you may want to take it in and have it checked to be sure the AFV is correct. Lean = Hot | ||

This happened to me on initial start up after doing some internal mods...I hadn't set the timing correctly.. | ||

It happened to me on my Cyclone after removing the headers, and putting them back on with a new gasket. Left it idling in the driveway for a little while at night, and when I went back over to pull it in the garage I saw a red glow from the headers where they joined the engine. Scared the crap out of me. I don't know if there was a short duration exhaust leak due to the exhaust seals sealing, or if it was all the penetrating oil that was all over the area, or what. I am not sure they don't glow after a hard run normally... | ||

Here's a temperature / color table for steel. These are for day light conditions. I think what you are seeing is not out of line for dark / no light conditions. The tops of the headers are blue which putts them in the 500 to 600 degree range for day light. 2000F Bright yellow 1900F Dark yellow 1800F Orange yellow 1700F Orange 1600F Orange red 1500F Bright red 1400F Red 1300F Medium red 1200F Dull red 1100F Slight red 1000F Very slight red, mostly grey 800F Dark grey 575F Blue 540F Dark Purple 520F Purple 500F Brown/Purple 480F Brown 465F Dark Straw 445F Light Straw 390F Faint Straw | ||

I've seen my XB12R header turn a slight red. I was letting the bike warm up one night in a dark parking lot and ended up getting stuck on the phone for a while with the bike still idling. The bike had been idling for upwards of 10 minutes before I noticed the header had a slight glow to it. It's not something I would have noticed in the daylight, or even in a well lit parking lot. The bike was bone stock at the time. Mike L. '04 XB12R | ||

the glow is only noticed in a dark, almost pitch black garage, it the city lights not noticed. my question is if it is running lean, what needs to be adjusted, and what differences will i notice. thanks, dan | ||

One thing that you have to remember is that the combustion gases are around 2800 degress F. When the exhaust valve opens, the gases are still burning and hot. So the pipe will glow. When I was in engineering school, we went to an automotive lab to observe a Ford in line six cylinder engine run on a dyno. When the throttle was openned up for the engine to run at about 5000 rpm, the manifold and exhaust pipe got red hot almost immediately. Air cooled engines can't regulate their heat, and when they are pushed hard at high revs, they will get really hot and will eventually lose power. This is why water cooled engines are superior in performance. | ||

reduc, dont worry about it, you can not adjust the idle mixture. | ||

My yamaha YZ400F does the same thing. That is why both the Buell and the Yamaha will burn through plastic (velcro knee puck area or moto-cross pants) in a heartbeat. You just don't see it unless it is very dark outside. xbolt12 | ||

Could be you're running lean as well. A lean mix will cause a motor to run quite hot. |
