My '14 had an issue where the exhaust piping under the seat had a bad seal, or the piping wasn't matching up properly, and exhaust heat and fumes were blowing past it causing the rubber grommets and fiberglass insulating washers to melt.
I didn't know it until I went to put on my DP CF heat shield and you're supposed to transfer that hardware over...well my rubber grommets were melted and fiberglass washers cracked. So when I went to the dealer to get new hardware, (which by the way, you can't get, its hardware that only comes with the heat shield) the service manager looked at my factory heat shield and said "you have bigger problems than melted grommets" So i took the bike in and they had to put all new piping in under warranty.
Is that maybe what you're smelling? Could be worth a look
