Late in the run, the 1997 machine wears the code XJ600SJC. Yamaha documented it in LIT-11616-XJ-63, the single service volume for the model from 1992 to 1998.
That is the number to quote and the number to check. Model designations from this period repeat across markets; the code and the part number together remove the ambiguity.
The manual is the original factory work. It gives torque figures, assembly clearances and service limits, takes the engine and chassis apart in the order the engineers intended, and includes complete wiring diagrams with the test values that make them useful. Troubleshooting is arranged by symptom, so a charging complaint or a hard-starting complaint each has its own path to follow.
Owners keeping a late SECA II on the road will find the specification tables are the part they return to most.
