750-4 just how does the stock airbox function?

If a somewhat smaller airbox of the same basic design (still common to all the carbs with a central inlet) was made, would the carbs work just as well?
Thanks!

I'm a wastewater engineer so I deal mainly with water hydraulics,and various biological processes the make some people squeemish, so air flow isn't my forte. However, I have taken those 34's apart numerous times and know where things are. The port that draws the air out of the vacuum chamber (thus raising the needle) is located on the intake of the carb before it enters the main carb chamber. When you twist the throttle, you increase the velocity through the carb, creating a lower pressure across the port which then draws more air out of the vacuum chamber, raising the needle.....) If you don't have a steady supply of air, I think you're going to get turbulance at the intake the the carb and that will affect your vacuum draw.
My thoughts on the matter. Can't really say how small you might make your airbox and still get it to work. You might what to ask Wiredgeorge.

The air boxes on our old KZs were designed with cost, ease of manufacture and noise reduction as the primary considerations. I strongly suspect that a carefully modded factory box could easily feed even a stoutly modified engine without the turbulance and tuning challenges of pods.
The pods, however, open up extra space for storage, blowers, NO2 and such. They also make removal and installation of the carbs MUCH easier. Some of us also like that intake roar when we whack the throttle.
Your mileage may vary.

I tried writing wiredgeorge at his website. He responded saying that he doesn't offer advice to people who are not his customers. Certainly understandable I guess, especially when his shop is busy, but no help. I'll research this elsewhere. But I think it would work, as long as the box envelopes all the carbs with a distinct opening.
wired george.....ahh...never mind....
