New bike muffler turned black

[Juice]

I just assembled my new bike about a week ago and my muffler changed from silver to blackish rainbow does this mean im running to hot cause the last thing i wanna do is blow my motor......thanx in advance any thoughts r appreciated

The bike seams to be running perfect also it might smoke here and their when stopped but it runs awesome

Oh im running 20:1 mix on the 3rd tip of 4 for my jets

Really hard to say, if it's getting hot enough to burn chrome in the middle of the muffler muffle then I'd expect that the rest of the engine should have self-terminated, I would blame it on a very crappy chrome job.

either too hot or too much oil residue sitting in muffler and catching fire

too lean at carb could make it hot, but I'd try 32:1 to see if it stops getting worse

Their does seam to be oil coming outta the bottom of the muffler i should try the less mix and hope for the best......like i said i dont want it gettin to hot n messin somethin up already. Lol.

That is really odd. I'm wondering if it is a catalytic convertor type muffler like Grubee is installing now?
I was wondering if they even worked but something is making heat in the middle of this muffler.

And where did the moccasins and battery come from? And what does the powercord go to?
The mysteries just keep coming...

Yes and how do you turn right?! The header pipe is overlapping the front wheel!

A cat could do that actually, come to think of it.

The battery is his camera battery he needed to replace before taking the pic lol..

every one I've seen had a converter-looking thing, but it is up a bit higher than the burned area (I use a VERY long drill bit to open that up sometimes if clogged)
