I have notice lately that I have a lot of little black spots on the back of my jacket I also seen it on my pants 1 day because I walked behind it while it was putting on my gear. I can't figure out what it could be. I notice that when I start my bike I see some little specs of fluids coming out but, once I rev it a couple of time then it's gone. I held my hand there just to see and it seems like condensation w/ the carbon build up inside of the pipes that's probably making it black to look like oil. I change my map recently but I don't if the bike being to lean or rich would cause that. Or is that something that I shouldn't worry about. It rides and sounds the same. Without any problem. Any suggestions?
