you adjust the nitrous/fuel mixture by putting in different size jets. if you run a dry setup, you have to increase the fuel delivery. too much nitrous and not enough fuel = by by motor. and you should run premium fuel all the time when spraying.

 

hey man, thers a guy on my old car forum selling a partial nitrous kit. everything but the nmu (which should be able to find reletively cheap on ebay).

run a wet kit...regardless of how limited to room you are all it is is a Y nozzle instead of a straight nozzle, and one more line and solenoid. Believe me if people on these boards can find a place to mount 2 HID ballasts AND a power commander AND a speedohealer all at once on these bikes you can find a place for a 2" by 1" solenoid no problem.
I'm sure there are plenty of people using dry kits, and I'm sure half of them don't have any clue what they are doing and will regret tinkering w/nitrous very soon.

 

Yeah that is what i did.....i used a dry kit on my F4i. But i also get it dyno tuned before something happened to the bike. That is just my suggestions, that if you go dry, then make sure that you have someone tune it when you are done.....you are not going to want to loose the motor.
