I have been riding my Savage since 1999 - how many times I have responded to this I cannot imagine.
The bang is from unburned gasoline pumping through your engine when the key is switched off an igniting on a hot spot - likely a peice of red hot carbon in the exhaust syste.
There is a carburator needlle trick that wi60 mph ll basically cure this but therre is also a riding style solution.
First - take your bike out for a good steady highway speed ride - 10 miles at 60 mph will do it - that will help clear all the extra carbon out of the exhaust
The next part requires modifying your riding style a bit. When you are riding and using engine braking - make sure you close the throttle completely all the time. Again the objective is to keep those unburned gasses out of the hot muffler. Finally don't come home from a ride and leave the engine idling - a few seconds are okay but don't let it cool while running.
You will not totally eliminate the backfire but you can reduce it to a mild woof!
