These OEM  Carb. diaphragms come complete with slides. They are not OEM Yamaha but look and perform exactly the same as OEM as they are made by the same manufacturer.
This allows you to replace just those that have failed, individually, instead of the complete set of four.
(Aftermarket manufactured ones may have a different thickness of diaphragms so they will not lift at the same rate as the OEM ones)
The OEM Yamaha price is £125 EACH, so this is a huge saving.
Fits all models of FJ1200.
Not suitable for FJ1100
