Yeah, it will tell you exactly what to do. There is also an 800 number on the card in case you need help. Depending on the kit you may change main jets, needles, slide springs, adjust float height and idle bleed screws. Some of the kits require that you drill out the main air bleed jet.
I have a Factory Pro 1.7 kit in my '95 ZX-6R. I was very impressed with the amount of R&D that went into it and how close the starting setting was.
