For the 2004 Silverado the code reads XVS65ATS. The manual has not changed: LIT-11616-XV-01, the volume Yamaha wrote for the 2001 through 2005 Classic and Silverado.
How to use the shared coverage
Start in the specification tables. They list figures by model code, so XVS65ATS tells you which column to read. The engine and driveline chapters then apply to your bike in full, while the chassis chapter has passages that belong only to the Silverado and others only to the Classic.
Beyond that it is a complete shop manual: periodic maintenance intervals, valve clearance, carburetor service, top-end and bottom-end overhaul with wear limits, final gear inspection, wheel and brake work, fork oil and seal renewal, rear shock service, and electrical testing with the factory wiring diagrams.
Order by LIT-11616-XV-01 once the frame plate confirms the code.
