Default Excessive backfiring during decelaration

When I let off on the gas on my 1989 FXRS it backfires like crazy. Does anyone know what could cause this?

how longs this been doing this,did you just do some mods to it?? If it just started and you've not changed anything,my guess would be a leak somewhere,maybe head pipe cracked?? head pipe to jug gasket broken/burnt out??Pipes/headers loose??If you've just done some mods,AC,mufflers/exhaust it may be running lean...?
