Well i have too long put off and time to tear into my 2016 motor to figure out what went wrong. Story is after returning from a 100 mile or so ride it smelled a little hot but not overheating at all. After shutting down and attempting to restart it cranks and no start and if i try a few times it pops or somewhat backfires lightly. Now i finally got our shop put up and now have room to work so starting out with first (front cylinder) spark plug electrode white and other two plugs look about normal. Looking like time to prep and pull motor, pull head and oil pan and see what failed and bring it back to life!
