Honda recommends using SAE 10W-30, JASO T 903 MA standard motor oil for optimal performance in the TRX420FA2.
It's recommended to change the oil every 100 hours of operation or at least once a year, whichever comes first.
Remove the air filter, wash it with warm soapy water, rinse thoroughly, and let it dry completely before applying air filter oil. Reinstall it carefully.
Check the battery connections, ensure the fuel valve is on, inspect the spark plug for wear, and verify that the engine stop switch is in the "run" position.
For optimal performance, maintain a tire pressure of 3.6 psi for both front and rear tires.
Locate the idle adjustment screw on the carburetor and turn it gently to increase or decrease the idle speed until it reaches the recommended RPM.
Check the EPS fuse and connections. If no issues are found, consult a Honda dealer as the EPS system may require professional diagnostics.
Clean the ATV thoroughly, change the oil, fill the fuel tank and add stabilizer, disconnect the battery, and store it in a dry place.
Inspect the brakes, check tire pressure, ensure all lights are operational, verify fluid levels, and check the throttle and steering for proper operation.
Maintain proper tire pressure, perform regular maintenance such as air filter and oil changes, and ride at moderate speeds to enhance fuel efficiency.
