Set of 4 high quality reproduction carburetor rubber diaphragms for the Yamaha models that have stock MIKUNI BS34 or MIKUNI BS36 carbs. This diaphragm is made from Viton rubber which is the best rubber to use for carburetor parts. Old diaphragms degrade over time and when they tear or begin to fall apart the carbs can't work properly. Don't use any carb cleaner or compressed air on the carbs with the diaphragms installed because the diaphragms can be damaged.
NOTE: Be sure to line up the rubber tab on the diaphragm so the slide is in it's proper orientation. May require trimming the tag on the outside edge of the diaphragm when fitting.
