Copping over my reply from another thread, this is what I did to fix the issue:
I took the above advice, went and got the ECU re-flashed, removed the fuel cut on deceleration, even got the mechanic to do a dyno run for a new fuel map, THIS DID NOT FIX THE ISSUE, but were on the right track.
Mechanic did some research, found out this was a 2013 specific issue, something to do with ignition timings he told me, so what he did was overlay a flash from a 2014 zx6r ECU, and also removed the motor for the exhaust valve controller (Exhaust valves and servo motors explained)
Once this was done , issue completely resolved, bike is noticeably smoother, easier to ride, easier to get back on the throttle, and you will notice the engine braking is way less harsh, making corner entry easier. Another bonus is when you remove the exhaust servo motor, the exhaust now has a really cool burble, popping on deceleration.
Apart from that , thanks for pointing me in the right direction, if anyone is in Sydney (not many places that do ECU flashing for some reason), BC performance in smithfield is where I got the work done, speak with Kelvin, he'll know exactly what to do.
