What's y'all's take on blueing pipes?

I've read lots of different things about it see it on lots of bikes.

 

The blue color is the normal result of exposure to heat, and, if you actually ride the bike, blue pipes are inevitable.


The pipes on my bike have been on the bike for 170,000 miles, and not only the pipes, but the muffler have turned a rainbow of yellow, orange, blue and purple hues. Odd thing, I get compliments on the pipes all the time. People ask me how I made them that color, tell me how "cool" they look, and so on. I tell them, "just ride the bike".


My take on "blue pipes" is: learn to embrace the blue. Wear it as a badge of honor, as testimony to the many miles you've traveled.

 

If you are talking about the pipe itself...the first couple of inches on a single wall pipe are gonna turn blue...if a double wall pipe, or the heat shield is turning blue you have a problem.

 

Glad yall are in line with me on it. People always want to assume it's running lean. I say no it's running great !

 

One more thing are evo's typical oil burners or lots of blow by ?
Seem to get a bit of blow by .

 

With 104,000 miles on my current motor, I'm using about a 1/2 pint in 2,000/2,500 miles, so I'd say, no, it's not normal for an Evo to use much oil. This will vary depending on ambient temp. and how hard the bike is run.

Is your Evo a head breather or a bottom (crankcase) breather? Some oil will come out the bottom breather if the bike has sat for a long time. It's not unusual to see a bit of oil seepage from the head breather passages during hard running. Is that what you're talking about?

 

Head breather I just put a quart in the bag yesterday.
1340 with an S&S flywheel and valve job not sure if that would make a difference or not.
She doesn't smoke at all but I have noticed discharge put of the breather and on my pants.

Just normal riding a few trips of over 70 miles but not hard riding. Since the oil was last full.

 

It is best to keep the oil about a half quart low.
If your breather hose still dumps into the carby, remove it and discharge below the motor, with or without a filter on the end.

Problem solved.

 

Depending on the age of the motor, it is possible the rubber "flapper valves" may have hardened from heat and age and need to be replaced. Also, it's not unheard of for the rocker box gaskets to come out of position between the breather chamber and the rest of the rocker box. If this happens, lots of oil can come out the breather, as the breather is open to the rest of the rocker box.


Both of these things happened to me about two year ago. I replaced the rubber valves and installed the latest OEM gaskets. Before, a hard run would soak the right side of the bike. Now, I get no oil in the breather at all (well, nearly none), and I don't have to run the oil level low, either.

 

Thanks for yall's time and wisdom I'll check out those valves and rocker box gaskets and let yall know what I find
