your plugs may be fouled. pull them and check for carbon buid-up, discoloration, etc. you may be able to clean them and adjust the gap. also, very much sounds like a timing problem. the timing could be off just enough to permit the bike to start but will not accept throttle, idles rough, & small back-fires through the carbs. hope this helps

1982 Honda cb900 custom and it backfires when you let of on the throttle what causes this?
I have the same bike, same year. First I'd say, is it really backfiring (small explosions in the tailpipes) or more "popping" when you let off the gas? I think backfires might be more common on giving an engine gas, not letting up... Mine was popping (which I originally referred to as 'backfiring', as well), and the diagnoses was that the engine was running lean, and when I had the carbs cleaned, it went away completely.
What causes a Honda 400ex to backfire when choke is off?
