Before everyone started using doublewalled pipes there used to be a product called "Blue Away" that would remove some of the blue. If you can find some try it after rejetting.



A perfectly jetted engine can actually give you a slight goldish tinge to the pipes near the exhaust ports.

I used "Blue Out" on some single wall URAL pipes and kept them blue free the entire time I had the bike. Just lotsa frequent pipe polishing...

You can adjust off-idle by just lifting the jet needle by resetting the clip to a lower position on the needle, which should have 3 to 5 slots. If that doesn't richen the mixture enough then go to a larger main jet.

Good posts here except that I'm not sure you really have a problem other than the pipes you installed are probably single-walled and are turning blue, which single-walled pipes will do. Straw-collered would indicate richer mixture, but ??



Does the bike pop on deceleration? Plugs look white? They should be tan in color. Does it pick up with hesitation off idle from a stop?



If you have no problems with any of the above then the bike is running OK. If any of the conditions exist then you may need to adjust the carbs. First try raising the jet needles one notch. Next would be to change the main jets to a larger size.



I traded an '81 Suzuki GS650 for a Yamaha in about '87 and only got $100. Dumb move.

Here's a good guide to pipe dizcoloration:



Blue: Pipe are bummed out. See a shrink.



Green: Overwatering. Or lack of drainage.



Brown: Exhaust port blockage. Use a mild

laxative.



Vermillion with a touch of Fuschia: Bike is gay.



Plad: Bike is Scottish. Cover pipe(s) with Kilt.



Black-blue: Pipes are most likely victims of domestic violence-hate crime, call police.



Hope this helps...burp...

There is a ceramic coating you can buy in a kit to line the inside of the pipes, it's sold for classic bikes to keep the chrome, uh, chrome. It's a pain to use (think gas tank liner, only for your exhaust headers and you get the idea) but if you desperately hate blueing its the only way to stop it.



Check your jetting FIRST, severe blueing is definitely a lean-fuel condition. Then you can decide if you want to line your pipes.

Also make sure your carbs aren't dirty, rust or dirt buildup can cause lean running, though it would also run like crap if that were the case.
