My 1979 Suzuki GS850 is backfiring when I let off the throttle....?

...Besides the Carb, what else should be checked?
This only happens when I am slowing down and am completely off the throttle. I would assume I need to check my gaps in the spark plugs. I guess that would help in the fuel/air mixture ratio. Maybe leaks around the exhaust? I just wanted to make sure I checked the simpler things before I go and rebuild the carb.

Thanks.
