After doing some research on the web I think I've figured out why people struggle to make these cheap kits work, these kits are what one would call a "dry-shot" of NOS, that means that only the gas N2O is injected from the nozzle into the carb.
NOS itself doesn't make power, but releases oxygen that when mixed with more-than-normal amounts of fuel creates massive power.
A "wet-shot" NOS system contains a seperate fuel nozzle that injects fuel alongside the NOS solving the problem of making NOS effective,
this means, as people have pointed out, that the carb must be rich to unleash the full effect of NOS, in normal jetted carb the NOS would simply create a lean condition, but when richening the carb, the bike wouldn't run right the rest of the time.
But I have a theory on how to solve the problem, open the choke to release more fuel and then hit the NOS. This would only work on carbs with a seperate choke-jet, not on carbs using a valve to block the venturi when the choke is on.
am I on to something? or am I just talking bullshit?

when you put the choke on the bike stalls and dies. thats how you turn one off without a killswitch.

In the winter here it's impossible to start any of my bikes without the choke on.
I guess you guys have summer all year around

When it's subzero degrees like it's here right now, you can kick your bike until your foot starts bleeding and it will still be dead, turn the choke on and it breaths life in one kick. It's the best friend in these temperatures. but anyway, the reason your bike dies when you turn on the choke is because the carb deliver much, much more fuel than the engine can burn with the oxygen it naturally draws from the air, Its an extremely rich condition, thats why I think NOS and choke together could work. and this without the need to run a too big main jet.

wouldnt you have to turn them both on at exactly the same time?

yes, thats the crappy part, I can see it all in my head, 4th gear wide open throttle, reach down to flip the choke, and turning the NOS on with my thumb by the throttle and BOOM! instant loss of control and most likely to crash violently. if it works...
