Hi everyone I am a new member to the forum and could use some help. I have a 2013 850 xp that won't start. I was out yesterday riding all day stopped for lunch and dinner and bike ran and started all day with out a hiccup even when I went to park it. Went out today to go out for another ride and notice bike was sounding rough when I was turning it over. Started to run but after it started to turn it backfired so loud it sounded like a gun shot. The engine light flashed twice out of the couple times I tried starting it but didn't stay on. The battery was week from the sudden drop in temperature last night but not sure if a weak battery would cause this. And where I could start? Thanks guys
