Backfires on deacceleration are often caused by leaks in the exhaust system - allowing oxygen-rich air to get in with the hot exhaust gases.
Try reinstalling your exhaust system using exhaust leak sealant.

Do you have a full system or a slip-on? Although I have a stock pipe right now, three aftermarket slip-ons and full exhausts I had in the past had this problem. I went with a fuel controller on Yamaha FZ1, FZ07 and Honda CB500F ...

Exhaust backfires/pops on decel can also occur when the idle mixture is too lean, which is a pretty common problem with today's bikes in order for them to meet EPA regs. Adding a PCFC with the proper idle mixture or getting a reflash would likely solve the problem. The addition of an aftermarket pipe tends to lean out the mixture a little, so it could cause the problem when no problem existed before the system was added.

Do these bikes have a PAIR system like the older ones? If they do it's a likely culprit.

Mine backfired with a Leo Vince slip-on, factory recall on the ECM fixed it.
