Installation Notes
- Safety first: Disconnect the battery and ensure the fuel supply is shut off.
- Carefully remove the carburetor assembly from the engine. Take photos to remember hose and linkage placement.
- Disassemble the float chamber bowl from the main carburetor body.
- Remove the old, compressed gasket. Use a plastic scraper to gently clear away any remaining gasket material from the mating surfaces.
- Ensure the groove and mating surfaces on both the carburetor body and the float bowl are perfectly clean and dry.
- Position the new gasket into the groove on the float chamber bowl, ensuring it seats evenly without being stretched or pinched.
- Carefully reassemble the carburetor, torquing screws to manufacturer-specified values in a star pattern to ensure even pressure.
- Reinstall the carburetor onto the engine, reconnect all lines and linkages, turn on the fuel, and check for leaks before starting.
Troubleshooting & FAQ
How do I know if my float chamber gasket is failing?
Common signs of a bad gasket include visible fuel leaks or stains on the outside of the carburetor, a strong gasoline odor around the engine, poor or rough idling, stalling, and difficulty starting the engine. A visual inspection may reveal a cracked, brittle, or overly compressed gasket.
Will this fit all Yamaha V4 and V6 engines?
This gasket fits a broad range of carbureted 2-stroke V4/V6 engines from approximately 1996 to 2005. It does not fit fuel-injected (EFI, HPDI) or 4-stroke models. Always use the detailed compatibility table on this page to verify your exact engine model and year before ordering.
What is the difference between part 64D-14384-01-00 and 64D-14384-00-00?
The part number 64D-14384-01-00 is the current, active OEM part number from Yamaha. It officially replaces or "supersedes" the older number, 64D-14384-00-00. Both refer to the same part in terms of fit and function; this gasket is a direct replacement for both.
Should I use any gasket sealant or adhesive during installation?
No. This gasket is designed to be installed dry. Using RTV, silicone, or any other type of sealant can interfere with the seal, cause the gasket to swell or deform, and may lead to debris contaminating the sensitive internal passages of the carburetor.
