Model code YFB250FHGR belongs to the 1996 Timberwolf 4WD, and its factory service information is in the book Yamaha catalogued as LIT-11616-09-11.
Coverage runs 1995 to 2000. A single volume across six model years sounds like a compromise until you are actually using it; then it helps, because the specification tables carry each year's values together and you can see whether a figure changed after yours.
The content is straightforward shop material. Maintenance schedules and the adjustments they call for. Engine disassembly, measurement and reassembly in Yamaha's own sequence, with service limits stated. Carburetion and ignition specifications. Electrical tests with expected readings. Chassis repair covering suspension, steering, brakes and final drive. Complete wiring diagrams, plus troubleshooting charts keyed to symptoms.
Confirm YFB250FHGR on the frame before you use a torque value out of the tables, and the rest of the book falls into place around that code.
