Haven't really invested a whole lot of time and effort on this one, but i did do a little experimentation with a ghetto-supercharger system, and the results were quite interesting.
Now I'm not 100% fluent with how and why a supercharger works, but the basic concept I have of it is that it's a blower that crams more air through the carb, which also at the same time makes it draw more gas, cramming in more air & gas per stroke, which would be sort of like being able to open the throttle more than usual & the more powerful explosion = more pressure on the piston & eventually the wheel.
So I had a pretty powerful blower laying around, one of those colman airbed inflators. The pressure isn't really all that great, but it does move a whole lot of air very quickly. So I said screw it, removed my air filter and pointed the thing through the carburetor hole.
After a couple tries, I was able to get it a certain distance from the carburetor and it rev'd up without stalling. Went through the RPM range with the throttle, and at no point did it bog down or anything unless I accidentally moved the pump (I was holding it with the other hand). It rev'd up a lot higher than normal at all ranges without bogging down or delaying the throttle.
So I'm thinking about finishing this when I have the time and money. The carburetor cover would get a hole cut in the front of it with an intake piece coming out and rigged up to a hose running to the pump, and at some point there would be a 3-way pipe fitting normally used for joining two pipes into one. At the end of one of those spots would be a valve opening up to the outside, decreasing both the amount of air and pressure going into the carburetor and since it's a valve it would be able to be tuned properly. The only complication would be the fact that this air pump runs somewhere near 150 watts, in which case I'd need to find a suitable battery and a power inverter & mount it on a rear rack.
Since it's run off a battery, the system would be able to be switched on and off (big red push button) from the bars to conserve power and only be run when necessary. This would also make tuning it easier if the power-band ends up being limited, tuning it to either perform during hill-climbing RPM's or MAYBE to get a little speed out of it (would have to gear the bike differently so as not to over-rev the thing), and shutting off the system during all other stages of driving.
EDIT: Was thinking one of those small batteries meant for electric scooters, as they can power a 250-watt motor for an hour straight & handle draining and recharging pretty well, unlike an automotive battery. Plus they're considerably small, light, and inexpensive.
