The FZS runs slightly rich from the factory. No need to change the carb jets when adding either a K&N or a different end can. Just reset the TPS and balance the carbs properly to fully enjoy the (slight) increase in performance. The most apparent difference I found was in the mid-range where it just smoothed everything out nicely.
