no problem mate. if you want to know the inns and outs have a look over at
Nitrous kits for cars and bikes - Wizards of NOS under the technical section, plenty of FAQs in there and if you dig deep enough i think there is a few online manuals too.
just FYI, off nitrous i run an A/F ratio of about 12.5:1, on nitrous this is closer to 10:1 but with the added fuel that enters with the nitrous to balance it out nicely.
