my 2012 with 7 miles had a plugged pilot jet. disclaimer: the bike was completely disassembled and sat for a little while. the point is, these pilot jets have TINY inside diameters and get plugged very easy. dont know how it happened in my case.
i checked everything else, and finally found it using a IR temp gun on the exh pipes. one was def cooler than the other.
good news, the repair doesnt cost anything. bad news, pulling the carbs are a royal PITA. found that loosening the airbox and removing the LH rubber carb adaptor helps.
once apart, remove the float bowl covers and take out the pilot jet (the little one next to the main jet). you should be able to see light through it. if not, compressed air. or take a tiny brissle from a fine wire brush and push it through.
