The recommended oil for the Suzuki KingQuad 400ASi LT-A400F 2019 is 10W-40, specifically formulated for four-stroke ATV engines.
It is advised to change the oil every 3,000 miles or every six months, whichever comes first, to ensure optimal performance.
Check the battery connections, ensure the fuel valve is open, and inspect the spark plug for any signs of wear or fouling.
Keep the battery charged, clean the terminals regularly, and ensure the ATV is stored in a cool, dry place when not in use.
The recommended tire pressure is 4.0 psi for the front tires and 4.0 psi for the rear tires. Always check the owner’s manual for the most accurate information.
Remove the air filter cover, take out the filter, clean it with a mild detergent and water, let it dry, and then lightly oil it before reinstalling.
Check the coolant level, inspect the radiator for blockages, and ensure the fan is operational. Avoid running the ATV at low speeds for extended periods.
Ensure regular maintenance, keep the tires properly inflated, remove any unnecessary weight, and avoid rapid acceleration.
Check the fuses, inspect the wiring for any damage, ensure all connections are tight, and test the battery voltage.
Use a spanner wrench to adjust the preload on the shocks to increase or decrease stiffness, depending on your riding preference and load.
