Description
The Keihin 1202 822 2000 main diaphragm gasket is designed to restore the critical seal around the fuel metering diaphragm in many OEM style and CDKII carburetors. When the original gasket compresses or deteriorates, it can allow unwanted air and fuel movement that throws off metering and makes tuning unpredictable. Installing a fresh gasket returns the diaphragm assembly to proper clamping pressure and helps stabilize mixture across the entire throttle range.
This genuine Keihin part fits a broad family of 28 mm, 38 mm, and 40 mm carburetors used on personal watercraft and other powersports applications. The material is selected for compatibility with modern pump fuels and premix oils, offering long lasting performance even in demanding marine environments. Including this gasket in a rebuild is an important step toward achieving the crisp response riders expect from a properly sorted Keihin carb.
