It is recommended to change the oil every 3,000 miles or every 6 months, whichever comes first, to ensure optimal performance and longevity of the engine.
A high-quality 10W-40 motorcycle oil is recommended for the DR-Z400SM. Ensure the oil meets JASO MA or MA2 standards for best performance.
The DR-Z400SM features adjustable front and rear suspension. For better handling, adjust the preload, compression, and rebound damping according to your weight and riding style. Refer to the owner's manual for detailed instructions.
The recommended tire pressure is 22 psi for the front tire and 25 psi for the rear tire. Always check tire pressure when the tires are cold.
If your DR-Z400SM is having trouble starting, check the battery charge, ensure the fuel is fresh, inspect the spark plug, and verify that the kill switch is in the correct position.
Regular maintenance includes oil and filter changes, chain lubrication and adjustment, brake inspection, tire pressure checks, and inspecting the air filter. Follow the maintenance schedule in the owner's manual.
To clean the air filter, remove it from the airbox, wash it with a mild detergent, rinse thoroughly, and allow it to dry completely before applying a light coat of air filter oil. Reinstall carefully to ensure a proper seal.
If the engine overheats, stop riding immediately and let the engine cool down. Check the coolant level and inspect for leaks. Ensure the radiator is not blocked and the cooling fan is operational.
To improve fuel efficiency, maintain proper tire pressure, use high-quality fuel, perform regular maintenance, and avoid aggressive acceleration and braking.
Common electrical issues include battery discharge and faulty connections. Ensure all connections are clean and tight, and the battery is charged. Use a multimeter to check for continuity and replace any damaged wires or components.
