To perform an oil change, warm up the engine, then stop it and place the bike on a stand. Remove the oil drain plug and let the oil drain completely. Replace the oil filter, reinstall the drain plug, and fill with the recommended grade and amount of oil. Check for leaks and ensure proper oil level.
The recommended tire pressure for the KTM Duke 390 2019 is typically 29 psi for the front tire and 32 psi for the rear tire. Always refer to the owner's manual for specific recommendations based on your riding conditions.
To adjust the chain tension, first place the motorcycle on a stand. Loosen the rear axle nut and adjust the chain using the chain adjusters on either side of the swingarm. Ensure the chain slack is within the recommended range (usually around 5-7 mm), and then retighten the axle nut securely.
If the bike won't start, check the basics first: ensure the kill switch is in the 'run' position, and the side stand is up. Verify that the battery is charged and connections are tight. If the issue persists, check the fuel level and the functionality of the fuel pump. If necessary, consult a professional technician.
Regular service intervals are every 4,500 miles (7,000 kilometers) or annually, whichever comes first. However, for optimal performance, consider more frequent checks of critical components like the brakes, chain, and fluid levels. Refer to the service manual for detailed maintenance schedules.
The KTM Duke 390 2019 requires a high-quality, ethylene glycol-based coolant with corrosion inhibitors suitable for aluminum engines. Ensure the coolant is mixed with distilled water at the recommended ratio, typically 50:50.
If the bike stalls, check the air filter for blockages, ensure the fuel is fresh, and inspect the fuel injection system for issues. Additionally, examine the spark plug for wear or fouling. If stalling persists, a thorough diagnostic by a qualified technician may be necessary.
To replace brake pads, first remove the caliper from the disc. Push the pistons back to make room for new pads. Remove the old pads and install the new ones, ensuring they are properly seated. Reinstall the caliper and check for proper operation before riding.
Clean the bike using a mild detergent and water, avoiding high-pressure sprays on sensitive areas like the engine and electronics. Use a soft cloth or sponge, and dry thoroughly after washing. Lubricate the chain and other moving parts once dry.
To reset the service light, turn on the ignition, and use the mode and set buttons on the dashboard to navigate to the 'Settings' menu. Select 'Service', then hold down the set button until the service light resets. Confirm the reset by checking the dashboard indicator.
