ZXR 400 Rough below 5-6k boggy + backfire any ideas?

Hi All just new to ZXR'S and this forum
So I have bought a ZXR 400 L9 with 531 miles on the clock, It has been sitting in the showroom of a racepaint company for 16 years and hasn't been ridden in that time.
So about me, I do most jobs on my bikes the only thing i won't touch is gearboxes
The last carb bike I had was a Honda Nc29 years ago.
So far I have
cleaned inside of the tank
cleaned carbs ( air compressor and brake cleaner )
set idle to 2.5 turns out ( same as it was )
new plugs
new oil
new coolant
new air filter
The bike struggles up until about 5-6k then comes to life, and if you take it to redline it with backfire.
Now im not familiar with these bikes atall so if there any common symptoms I have mentioned? If so any help would be much appreciated.
Thanks all
Reggie
