She will be running rich in the lower part of the throttle movement for sure....

One of the guys here will have a map file that they can send you that suits better for the time being.

But, give us some info first... What octane fuel are you running ? Is it straight or ethanol blend ( % ?)
What cans have you got on her, and is it still twin pipes or 2 in 1?
Finally, have you got an aftermarket air filter in it ?

Also, the TPS and throttle bodies are probably in need of some love....
Before you do anything else, balance the throttle bodies, then set the TPS adjustment......

Yeah, a new map will pretty much fix most of that....

BUT, i just remembered this one thing you have to do ASAP....

Locate the small bent hose from the PAIR valve under the airbox that goes form the valve to the air box....

Righ thand side of bike..... pull it off the air box, then insert a ball bearing in it to block it off.
I actually pushed a allen head bolt in head first so it can be easily removed....
Then refit the hose to the airbox......

Most of that pop will be gone.....trust me....

There are pair valve eliminators out there in the market- they are not expensive and look nice. You get rid of a lot of useless stuff and make the front cylinder spark plug change a little bit easier. I got my kit from eBay a few years ago. Includes everything you need to completely remove the pair system.

With no pair valve system in effect I bet you won't have any backfires. At least I have none with my open akrapovic cans. If problem remains then I don't have a clue, maybe then the map is too rich.

Is the O2 sensor removed? Are O2 eliminators installed? This causes the bike to run in "default mode" on the base map, which can be rich in some areas. Blocking off the PAIR system (there are numerous ways to do it) will solve the decel popping on a properly tuned biked. 87 octane is all this bike needs. A PC3 map can be converted to a PCV map in the PCV software that can be downloaded from DJ. My PC3 map will not do you any good - I have Yosh cans, K&N filter, and opened up airbox - but if someone has a custom dyno tuned PC3 map for stock w/o baffles, it can be converted. You can always download a map from DJ - their maps are pretty rich which should be ok with baffles out, although mileage will drop 10% or more.

Isnt the O2 eliminator plug fool the ECU to think that the O2 sensor is still functional

No, that is a common misconception. There is a resistor in the O2 eliminator that mimics the O2 sensor heater so the ECU doesn't fault. The lack of an O2 voltage causes the ECU to run in "default mode", ie the base injection program, when it would be in closed loop, typically up to 20% throttle and 2k-6k rpm.
