Hi Patrick, welcome! I'll get @
ducatiman fill you in on things like carbs and airboxes. Generally the carbs are way more involved to get right than most, and modifying the intake system opens a big can of worms that you probably don't want open.
I don't know if the ZZR has the same airbox as my '05 Ninja, but if so you can cut the battery box off the airbox and make it 100 times easier to work on the carbs.
