Your just running a little rich. Backfire is caused from unburned fuel or bad spark plugs or timing. A tune or intake should help. Try looking at your plugs too. If your untuned then I wouldn't say its the timing which can also be a cause. A too "retarded" set timing will also cause backfire. Fuel injectors spraying fuel after cylinder has already combusted is another but that's not going to be it either. If i mixed anything up Feel free to correct me.
