Yamaha MXT9GTK Niken GT 2019 Owner's Manual

Regularly clean and lubricate the chain every 500 miles or after riding in wet conditions. Use a quality chain cleaner and a lubricant specifically designed for motorcycle chains.
The recommended tire pressure is 36 psi for the front tires and 42 psi for the rear tire. Always check the pressure when the tires are cold.
Check the battery connections for corrosion or looseness. Ensure the kill switch is in the run position and the fuel is sufficient. If the issue persists, inspect the starter relay and fuses.
Use a high-quality 10W-40 motorcycle oil that meets or exceeds the JASO MA standard. This ensures optimal performance and engine longevity.
Replace the air filter every 12,000 miles or sooner if you frequently ride in dusty conditions. A clean air filter improves performance and fuel efficiency.
Check the ABS sensor connections and ensure they are clean and secure. If the light remains on, have the system checked by a professional as it may indicate a malfunction.
Refer to the owner’s manual for specific instructions. Generally, you can adjust the preload, compression, and rebound damping to suit your riding style and load requirements.
Fill the fuel tank and add a fuel stabilizer, change the oil, inflate the tires to the recommended pressure, and store the bike in a cool, dry place covered with a breathable cover.
Maintain proper tire pressure, regularly service the engine, use the recommended grade of oil, and avoid aggressive acceleration and high-speed riding.
Inspect the tires for uneven wear or damage, check the wheel alignment, and ensure that all engine mounts and bolts are secure. If the problem persists, consult a professional.
