Burnt header heat shields?

Who among us (besides me) has burnt, overheated chrome header heat shields? I may be asking for too much, but I thought the reason for a chrome heat shield over the header was to prevent turning the chrome plating to bronze/brown/blue colors.

The chrome heat shield on my California has been changing colors from the flange at the exhaust port almost to where it begins to bend down.

Any comment?
 
Reading other posts on this shows that is normal, it is a single wall pipe, not a heat shield up there. So for it do discolour is normal. Lots look at it as a badge of honour, you use the bike, so the colour changes. The heat shields are down by the foot pegs/floorboards. If those are changing colour, that may be a problem
 
The C14 uses double walled headers, so if they are discoloring, it just visually confirms the science shown on the Air/Fuel graphs I have as uber-lean fueling and excessive heat. If you could see the color of the inner pipes, you'd cringe.
 
Do you allow the bike to warm up before riding or sit in traffic a lot? Any time the engine is running and the bike is not moving you are heating the pipes with no cooling air. I have seen bikes blue the length of the header pipes from people running them to charge the battery, warm up, etc.

On my California 1400 the header has a chrome heat shield starting at the exhaust port flange. I am sure they are all the same. When the engine is cold run your fingers around the header heat shield. You will feel ventilation holes on the inside (out of sight).

No, this is an electronically, fuel injected engine. I start and get rolling. No need for a warm up period.

I am just surprised to see the blue/bronze colors with the double wall. I have another bike with a similar arrangement and it remains clear with no discoloring. Maybe is has better air flow between the two layers.

No, I am sure they are highly heat stressed. What is the OEM air/fuel ratio on the California?
 
My 2014 C14 Custom is doing the same. Obviously running lean. Anyone found any metal/chrome polishes that do a good job of addressing this issue?
 
I looked closer at my pipes this afternoon after work, and sure enough it seems there are heatshields up there. And only one side is discolouring. Todd, I may have to rethink the fueling option after all!!
