Hey guys, just need some advice and input on what you guys think is wrong with my 954. It runs great, but when i really get on it, traces of black smoke come spewing out of my exhaust pipe. It also seems like on the inside of my pipea thick layer of carbon has accumulated. I have a power commander and supposedly it has the correct map. It would make sense that it was the power commander but i noticed the smoke before i even installed it. Any ideas or suggestions?

 

Its normal, our bikes run a bit on the rich side, just a little carbon.
