About the Yamaha XJ650
Carburetor, engine, fork and brake repairs across the XJ650 family.
The XJ650 family brings together Maxim, Seca and Turbo motorcycles with different service requirements. Yamaha’s fully faired 1982 Turbo used a carbureted, turbocharged 653cc four-cylinder engine. Its fuel-system requirements make the complete model designation particularly useful when buying parts.
Choose the XJ650 engine gasket set by year
Standard XJ650 engine gasket sets divide into 1980–1981 and 1982–1983 groups. The early set also includes specific Midnight Maxim and Seca applications. The comparison panel below links both standard sets so you can compare their coverage and contents before opening the engine.
Know your motorcycle before choosing partsYamaha XJ650 model differences
Start with the motorcycle variant. These examples show where engine and fuel parts separate.
Standard XJ650
1980–1981 and 1982–1983 engine gaskets
The standard XJ650 uses two separately listed gasket sets across these years.
Parts checkpoint: Use the engine year, then compare the supplied gaskets.
XJ650L
Midnight Maxim and Turbo
A 1981 Midnight Maxim gasket application is different from a 1982 Turbo float-valve application.
Parts checkpoint: The year is essential when a part uses the shortened L designation.

Seca repair parts
The Seca page includes carburetor, engine gasket and brake components explicitly covering 1982 XJ650R.
Parts checkpoint: Choose an R-model entry rather than assuming standard XJ650 coverage includes it.

Frame, engine & fitted componentsYamaha XJ650 identification checklist
Use these details to match your motorcycle and any replacement assemblies before ordering.
- Copy the frame/VIN and complete model code from the motorcycle, not only a tank badge or registration shorthand.
- Record the engine number if the engine has been replaced.
- Identify whether the bike has its original naturally aspirated or Turbo intake system.
- Photograph carburetor markings, brake castings and fork dimensions for the assembly being repaired.
