 You say 'problem', has it always been like this or has it become worse?
As I have become used to my bike I find that it has a tiny delay when wacking
open the throttle. If I want the bike to wheelie I find that I have to turn
the throttle a bit slower, if I turn it very fast there is a small delay
and the bike picks up speed instead of lifting the wheel. (anybody else notice
this??) 
    Anyway I think that it's caused by the slids in the carb opening too slowly
. The springs in the carb holding the slides down are too strong. I tried to
get a jetting kit that included weaker springs (which are available for most
bikes), but all the kits I could find only included jets and needles. (does anyone know of one that includes the springs as well? Will the springs form a kit for
a ZXR750 do?) Maybe I could cut them a bit? Any suggestions?

 Your bike is from Spain? Is it restricted?
I know the ones in the UK are restricted. This months Performance Bikes has
an article about derestricting ZZR11,GSXR11&FZR10. 
Specifically the ZZR is restricted by undersized carp tops, which reduce total
carb slide lift by 10mm. To derestrict it they fitted the carb tops from a
ZXR750H2. Dynoed before and after, gain= 8.3bhp (which might be greater still
at speed due to the ram-air effect)
