1x Vacuum release plate L for KEIHIN FCR RACING carburetors
Will fit all 35mm - 41mm FCR carburetors on dirt or street bikes.
The plate stamped with M stamping will not work for the FCR-Racing models, see my other listings for that slide.
The vacuum release plate is the loose plate on the flat slide assembly that serves as sort of a vacuum valve to help regulate engine vacuum, particularly when starting. Will also cause inconsistent idling when leaking or worn.
I highly recommended a new Vacuum Plate o-ring when replacing the slide, if the slide went bad its because the o-ring was not maintained and the extra movement caused the damage. I can offer a combo price on both - please send a message for it
