Does the bike backfire only when the throttle is being closed? The carbs have a idle enrichment circuit. If the idle enrichment diaphragms are stuck in the closed position, the bike will backfire when the throttle is shut down. You can't remove these parts for cleaning without seperating the two carb bodies (and then needing to synchronize the carbs after reassembly). A trick that worked for me...fresh fuel, and some fuel system cleaner in the tank...ride the bike at highway speeds for 20 -30 minutes...repetedly rev the engine to a high RPM then shut the throttle closed. The repeted application of high engine vaccum to the enrichment diaphragms freed the stuck diaphragms and the fresh fuel cleaned any gum and varnish that caused the trouble. I've put 20,000 miles on it since then with no backfiring.

Go here. There is a wealth of information on the V-Star. https://sites.google.com/site/vstar1100kb/home Section 8 has Shop Manuals that should have step-by-step instructions. Great site also for modifications.
