Honda recommends using 10W-30 or 10W-40 motor oil that is suitable for wet clutches, such as Honda GN4 4-stroke oil or equivalent.
The engine oil should be changed every 100 hours of operation or every 12 months, whichever comes first.
The recommended tire pressure is 4.4 psi for the front tires and 3.6 psi for the rear tires.
Check the battery connections for corrosion, ensure the battery is charged, and inspect the starter relay and fuses for any faults.
Stop the ATV immediately, allow the engine to cool down, check the coolant level, and inspect the radiator for blockages.
Remove the air filter, wash it in warm soapy water, rinse thoroughly, allow it to dry, and apply air filter oil before reinstalling.
Clean the ATV thoroughly, change the oil, add fuel stabilizer to the gas tank, disconnect the battery, and store in a dry environment.
Use the preload adjuster on the shocks to increase or decrease the tension according to your riding preference and load.
Common signs include squealing noises, reduced braking performance, and visible wear indicators on the brake pads.
Regularly inspect the battery terminals for corrosion, ensure the connections are tight, check the electrolyte level if applicable, and keep the battery charged.
