I know this is a bomb forum
Need some help and thought I would try you guys. Right now I run a HMF slip on open air box w/ k&N and proflow adapter, I am concerned with backfire. I am at a 170 jet with the air/fuel screw out 2 1/2 turns (maybe) Called the dealer and said I may be running rich. They suggested going to 165 jet. Have the stock piolt in there as well. I have carbon or black soot on the exhaust tip. There is no sputtering or backfire when accelerating just off throttle popping sometimes with a flame out the backWhat is going on? Thanks for the help
