The 1999 Wolverine is model code YFM350FXLCG, documented in Yamaha's LIT-11616-FX-36 alongside every year from 1995 to 2000.
Late in a generation is when accumulated revisions matter most, and a book that covers the whole run shows them. If a bearing, carburetor setting or clutch specification changed after 1995, the table tells you so and gives the value that applies to your code.
What the chapters cover: periodic inspection and adjustment, engine and transmission service with measurement points and service limits, carburetion and ignition specifications, electrical testing with the readings Yamaha expects, and chassis repair including steering, suspension, wheels, brakes and the drive. Wiring diagrams and troubleshooting material are included.
Confirm YFM350FXLCG on the frame, note the part number for any parts enquiry, and let the printed figures decide what goes back in and what gets replaced.
