The ACV adds fuel under high vacuum situations such as closing the throttle at high rpm. The pupouse of the extra fuel is to reduce decel popping.

 

People disable or remove it because if it fails, it makes the bike too rich at idle and can make oit tricky to set the fuel screw. I find just making sure it is good condition works best.
