Anyone else's bike doing this?

Mine is a 2009 Vision.

nope, where are they turning blue at? Whats done to the bike?

 

[MIPLAYSTATION]

Off the head on both cylinders all the way to the collector/X pipe.

 

[bubba]

you are talking under the shields? If so, it's normal. Stock bike??

This is normal. Stock bikes today have air injected into the exhaust to dilute exhaust gasses. This air creates additional burning IN the pipes for cleaner emissions. That is the reason for the chrome heat shields OVER the pipes themself. I like it!!! I find it neat that they chose the EXACT color of the pipes to match the illumination color of the gauges.

I have a '09 vis tour and it does the same thing. My goldwing friends are trying to tell me the bike is running lean but I don't think so.

Ah, there's no air injection into the exhaust and every motorcycle I've owned since 1976 has blued head pipes as did every chrome or polished single wall header I've ever installed on cars or boats.

1600 degree exhaust gas temperature tends to do that to pipes

Tell your goldwing friends to look beyond the plastic cover over their exhaust pipes and they will see plenty of bluing.

OK Good, Thanks for the info guys.

So, this bluing is normal? Bike has 2600 miles on it. Runs normal from what I can tell. My 2000 ZR-7 also blues, but that is a 4cy Carb.
I just emailed my service guy at the dealership for his feedback.

Get back it means it's going to blow!!!!

 

[VicVegas8ballz]

HAHAHA, well, I'll wear my asbestos pants!

5 year old thread...
The blue under the heat shields is fine especially on the heads.

Yes, normal. Thats why they use a sheild / pipe cover to allow the pipe to heat cycle while keeping that cool chrome or flat black look.

I'm with you, Bulldog. It's like a 5 o'clock shadow, or gray on the temples. Bike is aging gracefully, instead of sitting in a garage!
