Blue pipes

Postby apalachmac » Sat Jun 09, 2012 11:09 am



Just came back from my first extended ride on my New/Old 85 1200

Noticed the header pipes (all four) had darken up considerably.....Bike ran like a champ, no hesitation, good power, and smooth running through the gears

Should I be worried?

Blueing of pipes is normal, you can sometimes run a little richer and not effect engine performance but reduce the amount of blueing (Not sure thats a real word!!) but its a fact of life.. I would not be worried about it, if the bike was running well then everything is probably fine..

I would be worried. A normal running wing shouldn't blue the pipes. Pull your plugs and see what color they are. Normal plugs should be a light tan.

Bluing is a sign of running lean. What brand of gas and octane are you running?
Having said that about the only pipes that won't discolor are double wall.
Take the heat shields off a Harley if you want to see real discoloring!

If they are pure white, then you are running too lean, they should be a nice Tan color.. As all 4 are white, it is unlikely to be a bit of dirt in all 4 carbs, so either you have changed fuel, got a rip in the air filter or something has changed to cause a lean mixture.. It might pay to go up a size or two on the main jets.. If the plugs really are pure white, you might be damaging the valve seats..
