You're right Mike, you didn't answer my question!!!
Anywho, in doing my research last night, which consisted of keyword searching the forums, I came up on alot of discussion about pressure drops across interfaces, the airbox/carb intake being one of them, the other being the cylinders/exhaust, the root effect being the correct mixture of fuel and air for combustion. Before we get any further, I'll warn all of you that I've little to no experience overhauling carbs or engines. But I do understand concepts of pressure and temperature. And I have an engineering background if that helps.
So what I'm getting is that the air chamber /airbox interface is far enough removed from the critical carb intake interface, that no effect on performance is seen. Is that what you're saying Mike? FWIW I spent a few hours last night repairing the air chamber, using JB weld. You're right, I do want to keep it if nothing more than have a mount for the side panel. I did shove my camera phone into the airbox intake and captured a very dirty filter. I'm hoping that will explain why my bike seems to "engine brake" rapidly when the throttle is decreased. I was going to post the photos but for some reason couldn't find a way to do it. Perhaps I'm limited to 5 photos, or is it a hard space limit?
I also took photos of the wood mount I made for my Sears jack, as well as my bike sitting on it and strapped down and all.
Peace & Love
