carbon residue on exhaust tips?

[rightarm]

Hi guys,
I put rx mountain exhaust tips on my warrior this summer to dress my sled up a bit and noticed something after a couple rides this week. I seem to be spitting out some carbon or some black residue from the exhaust. I noticed it because of the silver colored tips. Is this normal? I am thinking that I am running too rich, but how do I adjust this? Any help is appreciated.

It should not be too excessive,clean tips and replace your plugs if they have been in there for 1 season or more.I have painted my 03 tips black to cover it up a bit but I usually don't have that much build up.

I switch from time to time. I ran a little Seafoam yesterday.

This post got me thinking about how I got tired of cleaning the carbon buildup off and decided to just paint the caps. Wow, I should have done this a long time ago! With the grab bar powdercoated now the whole rear end is tied together. I love this hobby! There is always something to do to make it look or run better.
