Yamaha YW50FXF Zuma X50 2015 Owner's Manual

Regular maintenance includes checking the engine oil level, inspecting the brakes, ensuring the tires are properly inflated, and cleaning the air filter. Refer to the owner's manual for specific intervals and procedures.
Use a high-quality 10W-40 four-stroke motorcycle engine oil. Ensure it meets or exceeds the specifications outlined in the owner's manual.
Check the battery for charge, inspect the spark plug for wear or fouling, and ensure the fuel is fresh. If problems persist, consult a professional mechanic.
The recommended tire pressure is 29 psi for the front tire and 33 psi for the rear tire. Always check the tire pressure when the tires are cold.
To replace the spark plug, remove the spark plug cap, use a spark plug wrench to unscrew the old plug, and install the new plug, ensuring it is properly gapped. Tighten it to the specified torque.
Possible causes include a clogged air filter, a dirty carburetor, or a worn drive belt. Inspect these components and clean or replace them as necessary.
Maintain proper tire pressure, perform regular maintenance, use high-quality fuel, and avoid rapid acceleration to improve fuel efficiency.
To adjust the brakes, locate the brake adjustment nuts on the brake levers and turn them to increase or decrease tension as necessary. Ensure brakes are responsive but not overly tight.
Clean the scooter thoroughly, fill the tank with fuel stabilizer, remove the battery and store it in a cool, dry place, and cover the scooter to protect it from dust and moisture.
The drive belt should be inspected every 3,000 miles and replaced if it shows signs of wear or damage. Refer to the service manual for specific replacement intervals.
