I have a 2007 Streetglide with 103in kit with stage 2 reflash. I recently am starting to get a heavy gas odor while the bike is idling or when I stand on the throttle and slow down you can smell gas sometimes. There is NO gas leak ive been checking constantly and was wondering with the recent switch from supertrapp slip ons to rush slip ons do I have to get my bike reflashed because something could be out of wack. Thanks for the help.
