Yamaha YFM80GX Grizzly 80 2008 Owner's Manual

Regular maintenance includes checking and changing the oil, cleaning or replacing the air filter, inspecting the brakes, and checking tire pressure. Refer to the owner's manual for detailed procedures and intervals.
Use a high-quality 4-stroke engine oil. Yamaha recommends using Yamalube 4, 10W-40 or an equivalent oil, ensuring it meets or exceeds the specifications outlined in the owner’s manual.
If the starter does not engage, check the battery connections, ensure the battery is charged, and inspect the starter relay and wiring for faults. If the problem persists, consult a professional mechanic.
Ensure the radiator is clean and unobstructed, check coolant levels, and verify that the fan is operational. If overheating continues, there may be an issue with the thermostat or water pump, requiring professional inspection.
To adjust the chain tension, loosen the rear axle and adjust the chain adjuster bolts evenly on both sides until the desired tension is achieved. Tighten the axle nuts securely once adjusted.
Common electrical issues include faulty connections, blown fuses, and dead batteries. Check all electrical connections and fuses, replace any faulty components, and ensure the battery is charged and in good condition.
The air filter should be inspected and cleaned every 20 hours of use or more frequently if used in dusty conditions. Replace the air filter if it shows signs of wear or damage.
For long-term storage, clean the vehicle thoroughly, change the oil, add a fuel stabilizer, disconnect the battery, and store it in a dry location. Cover the vehicle to protect it from dust and debris.
Maintain proper tire pressure, ensure regular maintenance, avoid high-speed riding, and use high-quality fuel to improve fuel efficiency. Regularly check and clean the air filter for optimal performance.
Perform a pre-ride inspection by checking the brakes, lights, tire pressure, and control cables. Ensure the throttle and steering operate smoothly, and that all safety equipment is functional.
