1981 Yamaha XJ550 Service and Repair Manual
One book, three seasons. Yamaha's publication LIT-11616-XJ-50 covers the XJ550 across 1981, 1982 and 1983, and the 1981 machine is coded XJ550H.
That span is an advantage when a bike has lived a long life and picked up parts from other years, because the differences between seasons are documented in the same text rather than scattered across three publications.
- Publication: LIT-11616-XJ-50
- 1981 model code: XJ550H
- Years covered: 1981, 1982, 1983
Content is the factory standard: specifications and torque tables, periodic maintenance, engine and gearbox overhaul, carburation, chassis work and complete wiring diagrams. Confirm XJ550H on the frame plate before ordering.
The specification pages give capacities, lubricant grades and adjustment ranges, and the troubleshooting chapter is arranged by symptom. Because the book was written for dealer use, the figures are the factory's own rather than an approximation of them.
