Part number LIT-11626-37-59 belongs to the 2024 YZ450FX service manual, produced for the model code YZ450FXR.
Engine procedures run in the factory order. Valve clearance measurement and shim tables come first, followed by cam timing, head and piston service with wear limits, clutch replacement and a bottom-end rebuild inside split cases. Fuel injection and ignition chapters give the specified test values, which is what you need when a fault appears only under load.
Elsewhere in the book
- Fork and rear shock service with oil quantity
- Brake, wheel and bearing procedures
- Frame, swingarm and engine-mount torque tables
- Wiring diagram and troubleshooting charts
Confirm YZ450FXR on the frame sticker before ordering. Read alongside LIT-11626-37-59, that code separates this year's literature from the ones either side of it.
