VF700F: holes in carburetor intake boots

I just discovered that I incorrectly installed intake boots after cleaning the carb set on my 85 VF700F. I did not rotate the boots for little holes at the bottom of each boot to face the little air intake tube in the carb's throat. Does anyone know what these holes do to the engine performance? Obviously, I could rotate the boots and check for myself, unfortunately, I already took this set off and replaced it with another one (I am having issues with the new one too, but this is the subject for another thread). So now I am trying to decide whether it's worth it to swap the old carb set back with boots properly installed hoping that it fixes the problem that I had. (The old set was running too lean 1/4-1/2 of the throttle; shimming needles helped a lot but never solved the problem completely; I could feel a significant surge in power around 1/2 of the throttle)

 

Just in case someone is interested in this issue I got the answer to my question. Rotating rubber intake boots on the carburetor set so that little holes in sidewalls are positioned correctly gave a quite notable boost to the engine performance at full throttle. Unfortunately, it did not resolve the midrange flat spot problem as I hoped, but still... So, if your carbs were ever serviced you might want to check whether your intake boots are properly installed.
