08' muffler tips turning colors

[opcm]

I just picked up a 08' Busa about a month ago,brand new left over. I just filled it up with gas the second time (high octane) and I noticed the ends of the mufflers turning colors (blueing?) with a light resaudue on them,most of it wipes off but you can still see some coloring.The first tank of gas was brand name high octane,should I drain tank and try a different brand? I had just got off the freeway (80mph) for about 30 miles.Other wise I LOVE IT!! I got my heli-bars and zero gravity sport touring windshield installed... awesome!! more touring mods soon w/pics.Thanks

Stock pipes or aftermarket? If aftermarket, they are likely cheap pipes without a heat sheild. Heat = blueing. if it's stock pipes, you need to get it to the dealership and see if your engine is improperly tuned.

Sorry I wipe'd them off allready and I dont think a picture would show the little coloring thats left.I'll go try and see if it shows up with the camera.

Does the residue come from the inside of the pipe? If so, you might be running too rich, which still means a trip to the dealer.

You should be running 87 octane only per the manual,

ditto! i have 900 miles on mine and no discoloration nor residue on my big snazzy stock chrome caps.

my manual says 90 or better.

'08; my manual states " Premium Unleaded gasoline with a minimum pump octane rating of 90 "

Anyway from my experience this is normal. It washes off when I wash the bike. It's under warranty take it back if you think something is up with the bike.

let the gas tank gets very low and fill up with premium gas 90+ octane. probably was a bad gas and you should run premium gas on gen 2 busa!

1st tank was 90+ premium,I'm going to drain the tank (2nd fill same brand) and try a diff. brand of premium,go for a freeway ride (80mph/30-40 miles),and see if it happens again.

Yes it's coming for the inside of the pipe.

Sounds like it's running too rich, which might cause excess heat.

actually, running LEAN causes excessive heat...

mine did the same thing, it did look like discoloration at first but it's only exaust residue on the chrome end caps, it wipes off. I have changed to a full system.

You dont have a clue man.

I feel really stupid. I obviously have no clue....really, I do , but I was not thinking straight. I think I was too fixated on the blueing aspect.

Forgive me for a brief attack of stupidity? I'm no mechanic and these things don't come naturally for me.
