I know some people have tried nitrous but it doesn't seem to be popular.
I understand why because you need to prop different for motor and nitrous.
But for people doing top speed runs at like the bug why not run a sprayed setup? I would imagine that 100 mph would be possible at the bug if nitrous was used.

You need to factor the weight of the n2o tank.
if you run you fuel mixture to lean, say bye bye engine.
Also nitrous will cause excessive engine and exhaust heat.

The bottle wouldn't weigh much. I mean you would have no need for a 10-15lbs bottle.
My setup would be,
5lbs Carbon Fiber bottle
And individual jets for each carb
I would also run a larger fuel pump to keep things from running lean.
I would also run a fuel pressure gauge.
Nitrous does cause more heat but if you run it even on a car for 21 sec or less your golden. I have ran large shots of nitrous in cars for along time. I don't see why a 55 shot for a drag run is impossible.

Lots Of People Do It, But They Have Stopped. It Gets Too Expensive On Parts Replacement

I know alot of the 4 stroke guys run n2o but your right, it is unpopular for the 2 strokes. Im sure that has something to do with it but I havent given much thought as to why. I know there was a good reason on the 2 stroke skis but I cant remember what it was. I probably have most of the parts needed to make a setup for the gpr (just need smaller jets).
Weight really wouldnt be an issue as long as its not mounted in the front. I can have my wiferide with me and not loose much speed as long as she sits behind me.

People are scared of nitrous because everyone thinks it can make things go boom. And really that is sorta the truth, it can. But when ran properly a nitrous setup can be more reliable than a turbo or supercharger setup. Since we can't run either of those on a 2 stroke....

Two strokes are real picky when it comes to air fuel ratio and timming. Makes it hard to dial it in properly on nitrous because You can't just throw a lot of fuel to it like you can on a 4 stroke engine. Also you have the heat issue, its magnified on the 2 stroke engine, its very small size, doesn't dissapate heat a well. And also, everyone knows too lean= too much heat and you seize.

on the 1300r's I would think it would be pretty dam safe if you spray with a spraybar into the ENgine compartment. ONLY to cool the motor once its goten heat soaked. Very small shot goes a long way. Also we got the efi comtroller and we can all add more feul on top.

Here is an idea for EFI
Nitrous express make these for a direct port setup.
I have used them a few times and they work great. The injector goes into the top of this thing. Then the thing plugs down into the injector hole. It adds the exact amount of nitrous and fuel needed.
