Quick question - rode whole day yesterday. I noticed my relatively new (45 hours) 2012 850xp was backfiring several times, especially when letting off the throttle and coming downhill. Anything I should look at?

Thanks.

Its common with new 850,s mine did the same thing it,s the ECU learning new air/fuel ratio.
If it doesent stop take it to the dealer and have them flasher the ECU.
