Exhaust bluing - cause?

Mixture - too lean? IE, it's too hot?

Timing - too soon or too late?

Cheap chrome.

 

It's an Armours pipe. I'm not bothered about a bit of blueing, but
noticed it colour up pretty quickly after first starting it and
wondered what are the causes, so as to help me adjust stuff.

 

Properly blued pipes are a sign the bike isn't owned by some boring old
**** who only tips along in traffic queues but knows how to enjoy the
thing.

 

Single skinned header pipe, most likely.

 

*ding* - as they say.

Why some people want to get rid of it is beyond me. I was slightly
disappointed the stainless headers I've got don't colour in that way;
they just went a dull grey.

 

How odd. Mine go a sort of golden colour. They only go grey when road
shit cooks on them over a period of time.

 

like it. succinct and to the point.

depends how much. If you get it hot so it blues the tailpipe, that's
probably excessive.

having said that, on the Z440 I had if you fired it up on choke (which had a
fast-idle mode) and ran it for a few minutes on the stand to warm it up, in
the dark, the top end of the headers actually got red hot. Only just, and
only visible in the dark.

 

Wot 'e said. Shows it's not a Honda.

My Firestorm's headers were bright blue, I had to spend an age cleaning
them back to shiny stainless steel when I was selling it, for fear
someone would think the bike had been caned all its life.

 

As if.

 

And you can polish it out with one of them polishing mop kits, leastways
you can on a Beemer

I did get rid of most of the orangey look too, but I'll stop at getting
the crud off next time, as I think otherwise I'm polishing away too much
s/s.

One of the things I love about SS. Even scratched and gouges can be
ground and polished out.

Not that I've ever had to. No, no.
