Rear Pipe glowing just a little

[Nathang]

The headers could be thin walled steel perhaps...

Stock, stock, stock.


You doubters tickle me. Even tho' it should be real annoying.

How dense do you think we are that we can't see with our own eyes

when our pipes are glowing dull red? ya'think we're drama queens?


We'll never know, but I wonder how many of you are really aware

that when you say you never saw your pipes glowing red

YOU ARE LOOKING AT A HEAT SHIELD ? ... and not the real pipe?

The reason I know, is because I had to get into a funny position to see

what was the source of the red glow coming out from behind the shield.

Smokeydog thanks for that reply, I dont have many friends with bikes yet.. thank God to guys like you and the rest on this thread...Mine is a little orange as your is probly is, I am a bit more relaxed now with your response....all you guys are great and i tell you wha, It saved me a trip to the stealers and $90....

You are correct Nathang,

It's very hard to see the actual pipe because of the heat shield. Mine (pipes) turned blue from the heat but you can't see them for the shield. I did finally see th blue reflecting off the oil tank.

These exhaust pipes are not the highest quality thus the need for the heat shields to hide the blue as a result of these hot running engines. Of course I've never heard of the pipes melting or burning through, but they are getting impressive heat because of the EPA regs especially when compared to bikes from earlier decades.

My sportster (68) never blued and when I went to straight drag pipes you could grab the back end with your bare hand (after shutting it off for a minute) without burning your hand.

I was told when I really got on it at night, the guys behind me could see flames out the back end. I never had any problems with it for the 10 years I rode it (except for 1 flat tire - nail)..

I bet if some of us look close enough at the end of a ride (at night) we may see some glow. if one or more reports it then others should be seeing too.

thats a great sense if humor, I like that...I never looked untill i changed my pipes and if i hed never changed them i would have never known they glow that dull red color....

Heck, I had an old (cant even remember the year...) Harley 125 enduro (I think it was a re-branded Aerimachi) that the exhaust glowed red on any time I rode it more than half an hour.

Now I gotta check my UC when I get it back from the shop too. Makes sense that it may get hot enough to glow a bit.

I'll take your word for it, I just never could imagine it really!!!

You know better then I would!!

I have never seen mine glowing from running hard.

I believe it is a cold-start enrichment w/fast idle and/or ignition retard feature.

Newer efi bikes and cars upon initial start up are in what is called "closed loop" for at least two minutes.

As far as glowing pipes, I've never noticed on any of my bikes. I have had flames come out before though. That's always a treat at 10pm.

Make sure when you look at it it's at night time...

I can understand it from a clold start but I am seeing it from rides I take like after 30 min or so, I think you should take a close look at your rear head pipe when it really dark and make sure to look behind the heat shield too. let me know if yours glow a Dull orange...
