Some bikes, like BMW boxers, always turn blue because the sharp bend gets very hot. Others, like new Harleys, turn blue because of excessively lean tuning from the factory. New Harleys have a decorative shield covering the pipes so the blue doesn't show.

It's some kind of oxidation reaction when the chrome steel gets hot enough to react with the air.I have always wondered why pipes turn blue?

Correctly tuned Kawasaki inline 4's (at leat KZ650s) do not turn blue. I say this as the original owner of a 46,000 KZ650 with original pipes that have never turned.
I think you're right, I just took the original pipes off my '78 650 and was amazed that they had very little blueing. They are very rusty and dented but no blueing I think tuning has a lot to do with it, doesn't run overly hot.

My SR's pipes are slightly golden but have not gotten any darker. Proper jetting is the key.
