The recommended oil type for the Honda TRX400X 2013 is 10W-40 four-stroke motorcycle oil. The oil capacity is approximately 2.1 quarts (2.0 liters) with an oil filter change.
To adjust the chain tension, first ensure the ATV is in neutral. Loosen the axle nut, adjust the chain tensioner bolts evenly on both sides until you achieve 1.0-1.4 inches of slack, then retighten the axle nut.
To replace the air filter, remove the seat by releasing the latch. Open the airbox cover, remove the old air filter, and replace it with a new one. Ensure the new filter is properly seated and the airbox cover is secure.
Start by checking the battery connections for corrosion or looseness. Examine the fuses for any that might be blown. If the problem persists, inspect the wiring for damage and ensure all connectors are secure.
The recommended tire pressure for the front tires is 4 psi, and for the rear tires, it is 3 psi. Always use a reliable gauge to check and adjust the pressure accordingly.
To clean the carburetor, remove it from the ATV, disassemble it, and soak the parts in a carburetor cleaner. Use compressed air to blow out any debris. Reassemble and reinstall the carburetor, ensuring all connections are tight.
Check the fuel level and ensure the fuel valve is open. Verify the kill switch is in the run position and the battery is charged. If it still won't start, inspect the spark plug for fouling or wear.
It is recommended to inspect the spark plug every 600 miles and replace it every 1,200 miles or as needed based on wear and performance.
Clean the ATV thoroughly, change the oil, and stabilize the fuel. Remove the battery and store it in a cool, dry place. Elevate the ATV on a stand to prevent tire flat spots and cover it with a breathable cover.
To adjust the suspension, use the preload adjuster on the shock absorbers. For softer terrain, decrease preload for a softer ride. For harder terrain, increase preload for better handling. Always adjust both sides equally.
