For starters, it's NITROUS, not Nos! Nos is simply a nitrous brand that flooded the riceboy car market in Fast & the Furious!
The dry nitrous kits are a poor man's setup as they are flawed.
You will at least need a fuelling computer (PC3 is fine) to allow for the sudden lean surge when the nitrous is injected. When you are riding without the nitrous being injected, your bike now has a very boggy/ rich fuel table = poor rideability.
If you activate your dry kit at say 6,000rpm and accidentally hit rev-limit (which is a fuel cut rev limit), your engine will have a massive lean-out & instantly destroy itself.
You can get nitrous controllers/ computers that have a specific fuel map when the nitrous is injected but can be expensive to buy & setup.
The wet kit is a much safer option as you can tune a perfect air-fuel ratio by using different sized fuel & nitrous jets.
You generally need an upgraded fuel pump to supply the extra fuel for the additional fuel line.
All this aside, your engine wasn't designed to have an instant 20+% torque increase and rods, crankshafts and pistons will all be compromised.
I'd be going a turbo kit & having the engine built with all the associated hardware to make it last.
