I think you need HELP!!! lol................. I just got some hi-temp, barbeque paint and painted the inside of my rush muffs................. Now all I see is black...........
Once I had my engine remapped I cleaned the tips out with brake clean and a rag, 1k miles later after remap no more soot. Maybe youre running too rich!
I also clean mine everytime I wash the bike. I usually use Never Dull or occasionally Turtle Wax Chrome Polish and a Q-tip for the screw notches. Will have to try Simple Green, hosing down is easier than polishing. +1 for running rich. I have the XiEDs and have not yet done anything about the air cleaner, but it is on the list.
