I have a 2016 Brute Force 750 EPS. I just got the break in service done a couple weeks ago. I was riding Saturday and as I let off the gas around a corner then hit it again it back fired . It wasn't extremely loud either . It did it again about 15 mins later and same situation , slowed down and hit the throttle and pop.
I couldn't tell if it came from Air box or exhaust as I had someone on the back.

What could cause this? I did get into more mid then I like a couple weeks prior so yesterday I cleaned the air filter really good hoping that was all it was..
