About the Yamaha XS500
Brake, carburetor and ignition details that matter when maintaining a Yamaha 500 twin.
Yamaha’s 500-twin history includes the TX500, its first production motorcycle with a DOHC engine and four valves per cylinder. On an XS500 repair, retain the motorcycle’s complete model and year when comparing TX500 and XS500 parts references.
The useful differences in this collection are in the hardware. The rear brake-shoe application lists 1975, while the rear master-cylinder repair kit lists 1976–1978. Float-bowl gaskets also split between 1976–1977 and 1978. Inspect the fitted brake and carburetors before choosing a nearby-year replacement.
Match the carburetor gasket to the bowl
Compare the carburetor markings, bowl outline and screw arrangement with the removed gasket. A sound bowl gasket seals the joint; fuel overflowing from the carburetor calls for a separate float and float-valve check.
Model and component checksXS500 rear brakes and carburetor changes
1975 rear brake
The featured rear brake shoes list XS500 1975. A later rear hydraulic repair kit addresses a different brake arrangement.
1976–1978 hydraulic repair
The linked rear master-cylinder kit lists these XS500 years. Match the installed cylinder and its repair requirements.
Carburetor gasket split
One linked float-bowl gasket lists 1976–1977; the other lists 1978. Match the carburetor and gasket profile, especially after a carburetor swap.
Yamaha XS500 identification checklist
- Record the exact XS500 or TX500 model designation and year from the motorcycle.
- Identify the rear brake arrangement and the particular hydraulic unit being serviced.
- Read the carburetor markings and compare the old float-bowl gasket before selecting its replacement.

Choose the repair, then open the product for its full application and package details.
Rear-brake service by year
Rear shoes and a master-cylinder repair kit service different assemblies. Check the bike’s actual rear brake before selecting the year-specific product.
XS500 brakes partsFloat-bowl sealing
Choose the gasket that matches the fitted carburetor and year. A float-bowl gasket seals the bowl joint; it does not replace a leaking float valve.
XS500 carburetor partsClutch plates and springs
The linked plate and spring kit list XS500 1976–1978. Inspect the clutch stack and compare each component separately before deciding on the repair quantity.

The selected condenser lists XS500 1975–1978. Check that the original points system is still installed; an electronic-ignition conversion changes the parts required.
