The Boulevard is a Royal Star with different furniture, and Yamaha covered it in the same book as the rest: LIT-11616-VZ-01. For 1999 the model code is XVZ1300AL.
Coverage takes in 1996 through 2001 and the Royal Star, the Royal Star Tour Classic and the Royal Star Tour Deluxe. Because the differences between these are largely equipment, the procedures hold across them, and where a figure is variant-specific the table says which bike it belongs to.
The material itself is factory issue. Assemblies are dismantled and rebuilt in the stated order. Inspection ends in a measurement compared against a limit. Torque values are given for the fasteners where guessing would be a mistake. Wiring diagrams are complete enough to follow a circuit properly, and the troubleshooting sections begin with what the bike is actually doing wrong.
Match XVZ1300AL to the code on your frame first.
