1982 Yamaha XJ550 Service and Repair Manual

Model code XJ550J identifies the 1982 XJ550. The service publication is LIT-11616-XJ-50, the same book Yamaha kept current for 1981 through 1983, with the year-to-year differences noted where they occur.

What a technician uses it for is straightforward. Reassembling an engine means tightening torques and clearance limits; getting carburettors right means the specified settings and the synchronisation procedure; chasing an electrical fault means the full wiring diagram and a meter. All of that is here, in the order the work is done.

Read the code from your frame plate. If it is XJ550J you have a 1982, and LIT-11616-XJ-50 is the correct publication.

A word on ordering more widely: because the same publication number serves three seasons, an owner who later acquires a neighbouring year is already covered. Troubleshooting works from symptom back to component.
