red hot exhaust headpipe?

Yeah think it is normal:

Other than the heat shield it looks exactly like the picture I took of my pipe.

That is actually the problem I am having with my 390, the pipe is getting so hot that it overheats my bike. Look how close the radiator hose is to the exhaust. Hopefully you don't have an overheating problem like I doo

My 570 never goes over 104 degrees C. Always starts. No boiling fuel. Never had to top up coolant.
I don't run heat shield wrapping around the exhaust or under the fuel tank.
I am running the Factory Fan Kit.

Every high performance 4-stroke I've had (3 Husabergs, 2 KTMs, ! Yamaha) would turn the head pipe red if it just sat and idled for any length of time. There is no air moving through the radiator to produce convective heat loss, nor any across the pipe either, so the air mass around the motor and pipe just keeps getting hotter and hotter. My FE550 will over-heat in 1st gear technical trail sections even when the temperature is fairly cool - I even had it boil over once. Radiator fans are a great thing to have for tight trail riding. I had radiator fans on my KTM 400MXC and they would come on every time the bike sat idling or rode in first gear for very long.

I first experienced the glowing head pipes right after I bought my first Husaberg (brand new '96 FE501) and was practicing starting it in my shop. Totally normal.

Yeah Glenn already recommended I ceramic coat the head and the pipe like he did since that solved his overheat problem. I am running everything on this bike, fan, ICE coolant, vented front fender, no thermostat. and stills boil,etc

Looks normal to any bike.

Most vehicles if idling, or revving in neutral will get red hot. I never forget the first time as a trainee fireman on the trains up North where I worked, my engine driver told me to go back and check the engines at night (normal duties).
When I opened the door of the locos engine compartment the turbo and exhaust were so hot they were almost white !!
Amazing site if you have never seen it before. If you look hard enough you can see bits of crap and build up breaking off and travelling through the manifold and exhaust system, it gets that hot it makes the metal see through ........

Hi, gang....
Any of you in the Southeast U.S might want to look at this - http://www.customcraftheaders.com/ and contact Jim Dugan.

My 2004 FE550 git so hot the stud cracked and popped of the header along with the nut.
Doesn't help that it is not a supported part any more. :cuss:

Guess I will have to see what MacMaster Carr can come up with. I believe it is a M4x16.
