you can buy the foggers off ebay or you could i payed £15 each for mine. but i did use just the one in the air filter box for a bit its a gpz1000rx
worked fine.

on the kit you have the bottle with a solinoid for the noz that you pipe to the fogger and theres a pipe that you tee off the fuel to a solinoid to
the fogger aswell.
if you are useing one fogger you can fit it to the air box but this isnt the best way but it does work.you should have a switch for on the carbs for
wide open throttle . because you dont want it coming on at low revs or you will prob brake the engine. but i have dont it
if you undo the two pipes off the foggers for the noz and fuel the jets are in the holes so you can change them to any size.

As already said, the best way is to have individual foggers on each cylinder which ensures even distribution. However you can just use one fogger
which is placed further up the airflow (in the airbox for example) but this can lead to uneven distribution.
Either way, the nozzles go back to 'pulsoids' which are basically solenoids designed to switch on and off very rapidly, controlling the
volume of gas & fuel to the foggers. Dry kits only have one pulsoid (for gas) - wet kits have two (for both gas & fuel)
Dry kits are more suited to FI engines that can increase the fuel flow via the ecu (if your injectors will handle it)
Wet kits are for carb engines - injecting more fuel as well.

What is needed for an R1 injection?
Sounds like a quick upgrade!

The same applies to both fi and carbs - basically you are just injecting more N2O and fuel to make a bigger bang. You can allegedly make 50% more
power safely, although I would be inclined to put a progressive controller in there to make it a 'softer bang'
The downside is that it is quite expensive to run and a full NO2 bottle will last a matter of seconds - ideal for the drag strip though.
Useful linky thing

I think I have watched too many "Fast and Furious" films!
I'll see if my R1 build will scare me first, but I expect after a while, it won't be fast enough!

Without wanting to pi$$ on anyone's cheerios...
Isn't NOS on a BEC a bit of a waste? After all, NOS is only good for short bursts (unless you've got a huge tank and an even bigger
wallet) which means the 99% of the time you're off the boost you'll be carting around 10kg of ballast (? how much does a NOS set up weigh)
which will upset the BEC power to weight holy grail.....
Just my 0.01p- but I'd keep NOS for CECs (ie heavier cars with bigger engines to compensate where the added weight of NOS is going to be less
significant)....

Of course discharging NOS and fuel into the airbox sets you up for a huge underbonnet explosion if you have even a minor backfire

In real terms 10 kg is nothing, difference is like someone fitting cheaper alloy wheels opposed to expensive ones.
Or a couple of extra pies n beers on a friday night!!!
Ask the turbo guys how much their set up weighs, i bet its more than a nos system!!
Good instant cheap power, go for nos, but dont get gready with the power hike, i have Nos to fit on mine but i think 25 hp is about the max without a
controller on my engine and prob 80 hp max!! IMHO

i doesnt really matter what its weight is my bikes got 100bhp more then most with it a 10pound bottle costs 45 to get filled up on my car. and you
can use it for as long as you want till it runs out. if you use a controller you can run it at diffrent powers for each gear and what revs it kicks
in. with the 25 jets on on the bike it lasts a long time but with the 100 jets and a 5pound bottle it doesnt last long but i only use it when i need
to.and if you are going to fit it dont use ptfe tape only use the olives. and ive got some and some pipes if you need some let me no.

if you need some foggers i can get some wizard of Nos foggers at trade price, u2u if interested
