I was told at coffee night last week that my smelled fuelly. When I replied that I havent had it tuned since I put the pipe on I was advised that the fuel injection retunes itself. Now my question is how does the fuel injection know to alter itself. My bike does not have and O2 sensor in the exhaust pipe. (A fact that I did not mention at the time cause I wasnt sure, The O2 sensor on the 2003 fireblade was fitted on the californian models only) Since the pipe was installed the bike smells like its running rich. Do I need to get it retuned or will the bike as I have been told, adjust.
