Got a question for you guys. After a fuel stop the other day, my bike was missing & backfiring. Made it home & changed the spark plugs, didn't help. Dealer has confirmed the fuel system has good press. & delivery, ect. Dealer has changed from 8 deg. injectors to 25 deg. injectors, still does the same thing. Dealer is puzzled as well. Anybody experience this with their bike? Its a 2006 Road King W/ 10K miles. thanks. Oh yea, the code showed a front cylinder missing.
