What do pipe colors tell you?

I've noticed that the exhaust pipe for #1 on my 04 919 looks different from the rest. I'm wondering if it can possibly be pointing to some kind of issue -w- ignition, etc... According to the buttdyno it's running fine, but we all know how precise they can be. Any thoughts? I plan on pulling the plugs this weekend, but was hoping to get a bit of insight before hand.

I apologize for the poor photo quality. The iBrick, I mean iPhone, doesn't have a flash.

I think they're all telling you to wet sand them and get some Mothers on there to bring the shiney back.

Pull the vacume line off the fuel regulator and see if fuel runs out of it, you might have a couple cylinders running richer than the others.

A good cleaning on them pipes would clear up that fuel problem real quick like!

Actually, It looks as if something got on the pipe and discolored it? Degreaser or cleaner of some type would be my guess...

I was under the impression that the headers on a 919 are not chrome but just solid stainless steel.

I use an infrared thermometer on the pipes of all my multi-cylinder bikes to see if the cylinders are all running about the same temps. Especially on the older, bikes with carbs you can tell if one is running leaner than the others. This way you don't have to even pull the plugs to tell.

They probally are, but even Honda parts are sometimes subject to issues in metal quality - Its probally nothing -
