Removing, Blue, on Header ?

Is their something, that you have used that works?

Have tried,  toilette bowl cleaner, paint remover, navel jelly.

Could have it, ‘ceramic’ coated, (Heat resistance), from a place in Wisc.
(Black or Grey little over 100.   Chrome color little over 200)

I want to, just  clean, ‘most’ of the blue off.
So if it, ‘grows’, I can see if I have to play more with the carb adjustments.

Playing with the ’97 LS650.  (The  RED  one)  (2nd one, 1st is the '06 S40)
Had to take the header & exhaust  off (of course),
to check the CCT.  Did that replacement, (2 hole, 2nd hole),

(Still waiting for reports, from those of you that have done that,
what, ’slop’, (if any), are you finding on the, ‘oil drive gear’.
Just 1/2 visible, under the clutch basket)

Cleaning off the oil that has blown back on everything.
Raised the seat, Checked the valves,
Little tidily things, Sepdo rattle, Headlight rattle,
beer can ‘gasket’, for, Header/Muffler. etc.

I have researched the, 3 top,  “Blue Removers/polishes’
and they all ‘polish’. Just polishing, I can just, use Flitz, Simicrone, Rottenstone,
or 1,200 grit wet/dry,  (with oil on it), paper.  They All, ‘polish’.
(Which is  REMOVING the top layer of metal)

Thinking thy may be a chemical that will just wipe it off?

Thanks

There's a post somewhere in the tech section about using aluminium foil soaked in dish wash to remove rust. Weather it works on blue, I can't say.

You will get the blue back again so long the pipe becomes hot.

Yep.....good chrome experiences the same temperature issues.  It is not a quality issue.

I jetted my bike with an O2 meter, I don't spend much time sitting in traffic except when Oldfellor takes me to Pigeon Forge or MMRanch takes me through Gatlinburg, and I have not blued my pipe in 6,000 miles of riding.

The most reasonable explanation I have seen is this one from Khrome Works:

"All chrome plated steel exhaust pipes or mufflers will "blue" or discolor when the surface temperature reaches 900°F. This can occur if the fuel mixture is too rich. Instead of the charge burning mostly in the combustion chamber, the mixture continues to burn after the exhaust valve opens, down the pipe, causing extreme heat and bluing of the metal and its plated surface in the most restrictive areas - most commonly the bends or the baffle area. Cleaning products, such as Blue Buster™, are available and when properly used are quite effective in removing most discoloration from pipes. "

Someone check my facts here.  I thought our header turned blue because of the excessive heat from burning lean.  Lean=hot.  Rich=cool.

I couldn't get mine cleaned up either.  I took it off, used an electric palm sander with 180 grit, then painted it with BBQ paint.  I tried high temp paint and it came right off.  With the BBQ I still had to start the bike up 4 or 5 times and gradually warmed it up to cure it.  Once a year I give it a little dusting with the BBQ and it has worked out well.

This looks like probably the best/least expensive way to remove the blue from the header:

It can be rich or lean... either will make your bike run crappy, and a crappy running engine works harder and gets hotter...
Mine was blue when I bought it,... caused by a bad leaking petcock...
Way... rich...

Also,.. idling too long in hot weather... inevitable here in Tucson...
... also,... mountain rides...
Also,... excessive time idling to warm the engine, or idling too long while tuning it...

Once it's a deep rich blue... no more worries... ...
