The big thing is hiding all the gubbins, you'll probably need a power commander too. More electrical draw which can be a problem if you are on wiring with no charging.
Maybe look at a megasquirt system to save power commander and stuff? Or kit to remap the stock box yourself.

Depending what series you race in it may be worth doing, you can fit ducati 749 throttle bodies which are a sight cheaper than flatslide carbs, or buy bored out TBs from Zoran at TWF which give a good power increase, again cheaper than flatsides.
