Pipe blueing

[xtreem]

Just a quick question. Is it normal for the pipes on my '03 525 EXC to slightly blue in the head pipe area up to where the 2 join into 1 or does this mean I'm lean? I am running 172 main, JD blue needle on #3, and a 45 pilot. I'm in Florida where the air is hot and humid.

Mine are blue and I'm runing rich if anything. I think blueing is just normal for stainless steel pipes.
