It's recommended to change the oil every 100 hours or 600 miles, whichever comes first, under normal operating conditions.
Use Honda GN4 10W-30 or 10W-40 oil for best performance, as it's specifically designed for Honda ATVs.
Check the battery connections for corrosion, ensure the battery is charged, inspect the spark plug, and verify that the fuel is fresh and the fuel valve is open.
The recommended tire pressure is 4.4 psi for the front tires and 3.6 psi for the rear tires.
To improve fuel efficiency, maintain proper tire pressure, clean the air filter regularly, and avoid excessive idling or aggressive acceleration.
Stop the ATV immediately, allow it to cool down, check the coolant level, and ensure there are no obstructions in the radiator or cooling fins.
Clean the ATV thoroughly, change the oil, add fuel stabilizer, disconnect the battery, and store it in a dry place covered with a breathable cover.
Perform an oil change every 100 hours, inspect the air filter every 50 hours, and check the brakes, tires, and suspension components regularly.
Adjust the shock absorber's preload settings to either soften or stiffen the suspension, depending on the terrain and load conditions.
Common issues include blown fuses and loose connections. Check the fuse box for any blown fuses and replace them, and ensure all electrical connections are secure.
