I wonder, if a simple cannister of NOS pumped into the airbox would be enough to make a difference--- They sell it at the place down the street--- not automotive grade, but medical grade--- it comes in a tank just like helium or oxygen---
Wouldn't pumping pure oxygen into your airbox have a similar effect?
NOS is a catalyst that helps oxy burn faster, but OXY is just as important to the engine/carb---
No button, just turn the knob on the tank a little-- Or, maybe pump some hydrogen into your airbox-- that sounds kind of crazy though.
Hooking an automotive style "push button" NOS might be harder, even impossible--- there must be something you could do--- we all agree it wouldn't be good for the moped....but it could be done...somehow....
OR--- make a 'fake' NOS kit--- just for "show" nice shiny can of "NOS" with some hoses that don't lead anywhere..... Just to 'psyche' 'em out.
