2019 Yamaha YZ250 Service and Repair Manual

Yamaha issued one service book for the 2019 two-stroke motocrosser and its cross-country sibling, and this is it: part number LIT-11626-32-20. The frame and engine work covered here applies to the YZ250K2, and the same volume carries the YZ250X alongside it, so an owner of either machine works from one set of procedures.

What the book covers

• Torque figures for engine cases, clutch, cylinder and chassis fasteners
• Step-by-step teardown and reassembly of the top end, crank and transmission
• Carburetor settings, jetting reference and ignition checks
• Suspension service, including fork and shock disassembly
• Wiring layout and electrical troubleshooting charts

Before ordering, match the code YZ250K2 to the sticker on your frame. That code, together with LIT-11626-32-20, is how Yamaha identifies the correct 2019 literature, and it is worth two minutes of checking rather than guessing from the tank graphics.
