Forum member 2strokd was kind enough to provide the information below for us. All credit for the info here goes to him.
I got a deal on this lil dry shot off of ebay, so i figured what the heck.
Let's see what it does on a stock 49cc Mina mill. Only mods are CVT related (Hoca vari and complete rear pulley).
I've seen this kit work at the track for short bursts of fun on fourpokes. Never seen one on a 2T in person though.
I thought about a bigger main, richer needle setting, etc but at first I think I will just unplug the enricher and give it a short hit.. Keep my ears open and go from there. Might be a good idea for me to put a head temp gauge on? Exhaust temp would be better.. Whatever I do, I want it as subtle as possible. I want this scooter to appear as stock as can be.
Well, this has been fun and its still running good so ide say its all been good so far.
I hooked the kit all up like the paper work said to. Here are some pics.
Line run inside panels.
When its all on and your on the scoot, the average person wouldn't notice anything.
I should have known better, but there isn't anything to regulate the flow of nitrous as the kit comes. I should have taken more pics, and I will when I change the jet. As the kit comes you get straight blast from the hoses inner diameter. WAY too much nitrous flow for this thing! I melted the plugs electrode right off, second hit. And the bottle was empty in no time! I don't see how this kit would work on any small engine as is?
It still got me home like this. Only about half a block but it chugged home at 1/4 throttle. Anything more and it would flood out.
I put a new plug in and it fired right up and ran fine.
Got to thinking about the nitrous kit, and the flow... I thought my jets for my Kymco Cobra might be about the same size and fit inside the nitrous hose?
Yep! They are small and fit right in there! I started out with a 70 main. Don't ask what the heck size nitrous jet that would be? The jets are M4, part# NK200.10.
When i hit the nitrous now it feels a lot more "controlled" so to speak. Hits pretty good and smooth, but not much stronger than a mild stocker hitting the pipe... but its working!!! Plug stayed together and looked good! Same stock jetting, 70 main and needle in the middle clip. Enricher unplugged. The nitrous lasted much longer this time, but wasn't really flowing enough IMO to be worth having on it. We went to a 80main. This time it hit harder but still "controllable".
Here is my son riding it with the 80 main jet regulating flow. He hits it at :10 in the vid.
Im not sure just how much quicker it is? I do know it is working. We haven't ridden side by side for scooter comparison yet..
Now our only complaint is that the bottles are too small.
I'd say the bottle lasts about one city block with this set-up.
All in all, I think you could tune your scooter to run and have fun with a mild shot of nitrous. Dry or not.. I cant speak for long term use yet, but we sure had fun today with it ;D It was fun to play around with, But I don,t think it's really worth it. The amount of little nitrous cartridges it takes is nuts. It just doesn't add up. Does help off the line, or just for some "passing" power.
This is the kit we are using. It goes through bottles fast.

The N2O cartridges are 16 gram, typically used for whip cream chargers. Here is one seller. You can find them easily on eBay as well...

Here is an example of a jet kit that worked with my nitrous kit. Not all of the kits sold appear to have the same fitting.

Again, I'm not suggesting this to anyone. IT COULD BLOW YOUR ENGINE UP! I am just experimenting and sharing as i go.
THESE KITS COME WITHOUT A REGULATED FLOW!!!! YOU NEED TO INSTALL A "JET" TO GET THE PROPER FLOW RATE. Jet is not included wit the kit!!!
Also, do not subject the nitrous cartridges to heat. They could build up pressure and fail (explode).
