Post up a photo if you get a chance buddy & I might be able to help? I've just sold my SP version GSXR250 and they're very similar to the big brother 400.

The two pipes should run to a white nylon junction that then splits into 4 pipes that attach to the side of the float bowls.
The valve on the airbox is opened and closed in relation to TPS and revs and pressurizes the float bowls.

I concur. I had to buy a brass joiner to connect the hoses to the 4 carbs as mine was missing.

You can connect some hoses to 'A' and simply have them hanging down into space. I did that on mine and it ran fine. They're only breathers and you can possibly get away with not even connecting any hose to them?
