ZX10R suspension mods

Hey people
Just got a second hand ZX10R and I was wondering if anyone on here has gone down the road of modifying the suspension, ie different spring rates and revalving etc etc.
Any comments, previous experience etc would be helpfull. It doesn't feel too bad at the moment, but they can always be improved.
Cheers
