The recommended oil type for the 2014 Honda TRX420FM1 is SAE 10W-30, Pro Honda GN4 4-stroke oil or an equivalent that meets or exceeds API service classification SJ or later.

First, check the battery connections and ensure they are clean and tight. Verify that the fuel valve is in the "ON" position and the engine stop switch is set to "RUN". If the problem persists, inspect the spark plug and fuel supply.
Regular maintenance includes checking and changing the oil, inspecting and cleaning the air filter, checking tire pressure, lubricating the drive chain, and inspecting the brakes. Refer to the maintenance schedule in the owner’s manual for detailed instructions.
To adjust the idle speed, locate the idle adjustment screw on the carburetor. Turn the screw clockwise to increase idle speed or counterclockwise to decrease it. Ensure the engine is warm and the ATV is on a flat, stable surface while making adjustments.
If your ATV is overheating, check the coolant level and ensure it is within the recommended range. Inspect the radiator for obstructions and clean any debris. Also, verify that the cooling fan is operational.
To replace the air filter, remove the seat and locate the air filter housing. Open the housing, remove the old air filter, and replace it with a new one. Ensure the filter is seated correctly, then reassemble the housing and seat.
The recommended fuel for the Honda TRX420FM1 is regular unleaded gasoline with a pump octane number of 86 or higher. Avoid using fuel with more than 10% ethanol.
To maintain battery life, keep the terminals clean and tight, charge the battery regularly if the ATV is not used frequently, and store the battery in a cool, dry place during extended periods of non-use. Consider using a battery maintainer to keep it charged.
