I'm not the authority on this, but I know certain metals change color when heated. I believe high quality SS turns to gold, and Titanium can change to various hues.

Your engine maybe running to lean causing the exhaust to be too hot.



Check your spark plugs, If the tips are:



white, you are running lean (yes, the insulator is white also).

tan is fine.

dark, you are running rich.

me262 is correct. Engine is probably running too lean. But there is another option. If your bike is equipped with an air injection system, to lower emissions, which a 1979 should not be..., this makes the headers run hotter and blue. Another guess, is that the pipe manufacturer did not use a double-wall design, which usually solves this problem, and you may be able to return them... the reputation of the pipe manufacturer should be strongly considered, when purchasing pipes, as if a problem as this arises, they should be willing to back-up their product with a replacement or a refund.

I always thought blueing looked cool. Why do people hate it so much?

Most likely your bike is running too lean. Most bikes run lean from factory. When you put on new pipes that allow for freer air flow they lean the bike out further. Either rejet or at least adjust the air/fuel mixture screws on the carbs.

All single wall pipes will turn blue. It's how far they are turning blue that counts. If they are blue a bit past the first bend, you are probably running just fine. If the pipes blue down to the second bend, you are certainly lean. Adjust jetting accordingly.

Air-fuel mixture screws aka pilot screws are for adjusting the air/fuel at idle and for use during carb syncronization. Correct me if I'm wrong but you have to adjust main jet size to affect the lean or rich condition at off idle.

Default Blue pipes

Try adding a couple of tabs of Prozac to each new tank of gas. If the bike is very new the Prozac might incline your bike to run head-on into a semi and take you with it.

Great answer. If somebody needs chrome pipes then go buy a new crusier with the chrome covers.
