Back firing

Bike is back firing a little bit, nothing major but when i'm slowing down at idle speed I can hear it back firing.... What could this be? I changed the plugs a month ago and it was running fine.. Also, I put good gas in it too.... Any ideas??? Thanks!!!!

RE: Back firing

had same problem with my bike, if the bike is carburated and you had exhaust work done try changing the jet to a larger one, thats what fixed my issue

RE: Back firing

Has it got racing tuner? Stage one? Put in on the Dyno.
