Back to the carb question - are the springs above the slides still fitted ?
Not all bikes had them ,so someone may have left them off, but they help to richen the mixture in transition.

And do you have the correct needles - I spent a lot of time on the carb on my BSA B44 VS before discovering that I had been supplied with the wrong needle - the symptoms were the same as yours and the correct needle fixed things instantly .

Dont know how to check the bing ones though
