Hi Folks

I have just had modifications done to my 2017 Iron 883's stock exhaust pipes. Had the baffle removed and replaced with free flow baffle, made the slightly sorter with aluminium end caps. It sounds incredible. I have now noticed a fuel smell that was not there previously. Obviously running rich now. I'm not putting on a heavy breather of fuel pack at the moment. Should the fuel injectors be remapped? And, if I can live with the fuel smell, do I risk doing damage to the valves if just left alone?
