1980 Yamaha TZ250 Service and Repair Manual

Part number LIT-11626-02-06 covers the 1980 TZ250 and the TZ350 in a single volume. The code for the 250 is TZ250G.

Yamaha documenting the two together follows the machines themselves, which shared their architecture and much of their hardware. Where the two differ the text distinguishes them; where they do not, one procedure serves both.

These were purpose-built racing motorcycles, and the factory book reads accordingly. Assembly sequences, clearances and inspection limits, torque figures, fuel and ignition specifications and the original wiring are stated without preamble, for people expected to be rebuilding between outings.

For an owner today it is the reference of record. Confirm LIT-11626-02-06 and the TZ250G code before ordering, since the sister model shares the same part number.
