I am resurrecting my 1884 Honda Nighthawk 700sc. It hadn’t ran since 95 but now that I have cleaned the tank; replaced oil, plugs, fuel filter, and air filter; it actually starts and runs. It has a hard time idling however and seems to backfire sometimes on a quick down-throttle. Is there a fuel additive anyone can recommend that will help clean the carbs?

You do not need to get new carbs if the only problem is sitting unused with gas in them. The best thing, as mentioned, is to take them apart and totally clean them. Or, you might want to try this first. Get a product called Seafoam. Put in the tank and run the bike at speed. It will run rough at first but if you can ride it at speed then this MAY (depending on how bad the carbs are gummed up) clean them out. This may take as little as 15 minutes riding time or as much as a tank of gas. If it still doesn't run properly after a tank then definately have to revove and clean the carbs.
