Air cut off valve (ACV) for the Honda CB400T, CX500 and many more. Once the old diaphragms become stiff due to age or they develop holes, they no longer function properly. Save yourself tuning troubles an pick up some fresh cut off valves! This set comes with 2 springs, o-ring and diaphragm. The fitment list below notes which model years used which spring.
Some bikes had one air cut off valve per carburetor, some just had one for a pair of carbs. Please check to make sure how many you need prior to ordering.
