This happened on my 2014 today. I bought it used Oct 2016 with 9K on the odometer. It was my primary bike until I bought my 2016ES in Jan 2021, which now has 153K and is my long distance tourer and rally bike. Other than routine maintenance and wear items both have had no problems to speak of. I did mangle the head/valves of the 2014 because I never performed a valve check until it wouldn't start one day at 199K. I recommend to do valve checks every so often Now I try to do them once year. I change oil/filter every 8000 miles and use whatever 10w40 synthetic motorcycle oil AutoZone has that day, currently its Valvoline.
A great hard working bike!
