can't see how it would work without an efi-
maybe stuffing more air down a carb would work- kinda like the old ram-air hoods back in the 60's... but you'd have to run a rich mixture I would think.
if my memory is correct, the ram air hoods worked off a vacuum and would open the ram when the carb's secondaries opened- dumping fuel down the intake and forcing air around the filter... and a partial vac line would usually run from the carb to the distributor cap to advance the timing a bit.

Not going to work.
A little back ground about myself so you know I'm not talking out of my a$$. I am an ATV/small engine mechanic and a drag racer building and racing 2500hp 10.5 outlaw mustangs.
An electric blower is just that, an air blower. Blowing air into the engine will not add power. The way a supercharger/turbo makes power is it compresses the air. Compressed air allows more to fit in the combustion chamber. More air/fuel makes more power.
Now if you can fit a good gas powered leaf blower to the bike it does push enough air to compress it in the intake. But then you run into the problem of fuel. A carb is not designed to have compressed air in it so no fuel will be pulled out of the bowl. The only way to do it is to either convert to EFI or get a blow through carb which I doubt they make for ATV's.
As for "Ram Air" all that is was a clever marketing scheme. Air travels into the engine at close to the speed of sound, so unless you're driving at the speed of sound you are NOT "Ramming" anything into the engine. But they did make a bit more power by pulling in colder outside air. Colder air is more dense allowing more to fit into the chamber.
