RE: BME Backfire?
No, but so is backfire.
Backfire is cause by lean mixtures and (combined with) late ignition, so take your pick. My Douglass Dragonfly motorcycle had an ignition timing manette, and could be made to backfire at will, much to my liking, though the neighbors did not.
Kickback is caused by early ignition timing, or failure of the electronics inside the ignition to retard the spark properly.
