2000 Yamaha SEROW Service and Repair Manual
The final year of the run is coded XT225M, and it shares its service manual with every SEROW back to 1992. Yamaha's part number is LIT-11616-XT-25.
On a last-year machine the breadth of the book is welcome. Parts changed during nine seasons of production, and because the factory kept one volume rather than reissuing it annually, the earlier specifications remain on the page next to the later ones.
Content is workshop material rather than an owner's introduction: fastener torques, wear limits, ordered procedures for engine and chassis, wiring diagrams drawn to the factory's conventions, and troubleshooting arranged by symptom. Verify XT225M on the frame plate, then work from the figures that code points to.
Nothing in it is aimed at a first-time reader; the pages go straight to figures and sequence.
