My aircraft experience is full rich is lower exhaust gas temperature and as you lean the mixture the EGT will rise to a peak then fall off. Normal operation would be to run a few degrees on the rich side to reduce fuel burn and look after the exhaust valves.
Exactly what I was taught in pilot ground school. The old Cessna 152 has a mixture knob, and as altitude is gained, the mixture must be leaned to prevent loss of power and potential carb icing. So, lean = hotter, rich = cooler head temps.
So what is the problem if the pipes are turning yellow? Can that be removed also?

Yellow is just a lower temperature discoloration. As temps rise, colors go from yellow to brown to blue.

With a normal aircraft carburetor with variable mixture adjustment, rich is cool, lean is hot, but only to a point. Aircraft carburetors have an enrichment valve to slightly enrichen the mixture during full throttle operation to help cool the cylinders during a climb at full throttle when there is less air cooling the cylinders. However for cruise, it is preferable to operate lean of peak Exhaust Gas Temperature in the Best Economy area of the chart where temperatures have started to decrease. Typically this is only possible for fuel injected engines where the injectors can be adjusted to get all the cylinder mixtures to be the same so they all peak at once. Of course a single cylinder carbureted engine doesn't have that problem.
So, lean to rich can increase exhaust temperature and rich to lean can increase exhaust temperature depending on from where you start. So, where on the chart is a stock S40? I'm guessing lean of peak.

When I bought my bike year ago, the dealer drilled out the brass plug and richened it for me and said they run on the lean side which cause alot of backfire and blues the pipes. Must have dialed it right in because at 53,000 my exhaust still looks new and the only bluing is maybe a 1/4 inch from the header. Hasn't backfired either since them except for the little pop when I shut it down. I have tried the Blueaway on other bikes tho and it is not worth the effort. Just ride it. Who cares!

This has gotten to be interesting and informative.
In looking at, blue remove options, I found this:
http://www.classiccoatings.com/prices.html#motorcycles
Of course their main thing is,
'keep the heat in the pipe', with a side of, 'looks good'.
If I had a spare header lying about, might think about it.
But don't want to spend 100 at steel-bay
then 110 + shipping to coat, just to experiment.
Although, 'Satin Black', on a, Red bike ??
Has anyone, 'ceramic' coated?

Lots of folks have ceramic coated - just not on this forum. All the street rodders and drag racers do this, as it is the only product that works on headers and holds up a long time. The lighter colors can ultimately get stained if you have an oil leak and it bakes on...but it doesn't peel off or rust for years.
You can get is done pretty cheaply at his company - $ 14 a foot for any pipe up to 2" diameter.

I've been toying with the idea of adding perlite to the header as internal insulation.
http://en.wikipedia.org/wiki/Perlite
drill a small hole at the top in the outer shell and pour it in, cover with a hose clamp or weld shut.

I really do like the blue...
I thought about taking the spring winding off the brake and speedo cables and blueing them with a torch,... but I couldn't figure out how to get the springs off the cables...
Bummer!... that would look so cool!...
...
Blue handlebars would look kinda' neat...
