Got a 2015 back in October. Took it to hunting property for work weekend Oct 10 and put about 80 miles on it so right around 100 total miles. A couple of times before that weekend it had small backfires when starting right after I stopped and then started it again. I got on it this past Friday for the first time since that weekend and it was way low on gas but when I turned the key it turned over maybe twice and bam! a huge backfire. It blew the throttle body out of both hoses/adapters to the head. I got some gas charged battery (it was dead) and started to crank it again and it sounded weird because throttle body was out of the hoses which I hadn't noticed. Got a buddy to turn it over while I looked under bed to see if I could determine why it sounded weird. While he was cranking a fire ball shot out of the gap between throttle body and hoses and there was a small fire inside one hose/adapter. Blew it out in seconds. Checked inside hose and they were smooth, no noticeable damage. I put the throttle body back on hoses and she fired right up and idled/ran fine. However, it did have another small backfire later after I stopped for a minute or two and then restarted. Looking for any input on this.
