2001 was the last model year in the coverage range of LIT-11616-05-80, and the RAZZ built that year carries the code SH50N. Yamaha's book, begun for the 1987 machine, closes with this one.
Everything a technician needs is there: service intervals, adjustment procedures, engine and automatic transmission overhaul with wear limits, chassis and brake work, torque specifications throughout, wiring diagrams, and symptom-led troubleshooting. Nothing in it assumes a dealer workshop beyond ordinary hand tools and a service mindset.
One practical note for a final-year machine. Parts availability is thinner than it was, so the manual's inspection measurements earn their keep — they tell you whether what you have can be reused instead of replaced. Confirm SH50N on the frame, quote LIT-11616-05-80 when checking with a parts counter, and you are working from the same document the dealer used.
