well its actually a maintenance thing. the butterflies get knocked out of sync when you ride. They slam open and closed and they are bound to get knocked out. or taking that part of the carbs apart will throw them out. I actually found a way to build my own sync tool. I will need four vacume gauges, quite a stretch of line, and four one way valves. One carb is set and has no adjustment, so the other three are to be set to match that one. Its actually a pretty simple process.
The gauges are cheap if you have access to HGR or a harbor freight tool store

When i bought the bike the guy said he put about 18k miles on it and never had them synced becasue he did everything himself but that. 
Im also getting ready to clean the carbs and i know you dont have to sync them if you dont touch what your not supposed to but since ill have them exposed i may as well. 
Ive also noticed that when i twist the throttle even at low rpms in a low gear it takes a few seconds for it to get going. It didnt do that about 500 miles ago. Im not sure if that would be caused by sync problems but it may help?
Since we are talking about whats wrong with my bike what would cause it to backfire a little as i slow down. Not really loud just small kinda pops. ill try to get a sound clip when i get it back together.

I just dug up my trusty clymer and the backfire can be improper ignition timing, Carbs improperly adjusted or a lean fuel mix. I guess ill try them till it stops. haha. Forgot i had this book
