For the Yamaha YW125MFG Zuma 125 2016, it is recommended to use a high-quality 10W-40 4-stroke motorcycle oil that meets or exceeds the JASO MA standard.
The oil should be changed every 2,000 miles or every 6 months, whichever comes first, to ensure optimal engine performance.
The recommended tire pressure for the Yamaha Zuma 125 is 28 psi for the front tire and 33 psi for the rear tire.
If your Yamaha Zuma 125 is having trouble starting, check the battery charge, spark plug condition, and ensure the fuel supply is adequate. Also, inspect the starter switch and fuses.
Poor acceleration could be due to a clogged air filter, worn spark plug, or fuel system issues. Inspect and replace these components as needed, and ensure the CVT belt is in good condition.
Regularly check the brake fluid level, inspect brake pads for wear, and ensure the brake discs are not warped. Replace brake components as necessary and bleed the brake system if the brakes feel spongy.
The valve clearance for the Yamaha Zuma 125 should be set to 0.10 mm for the intake and 0.15 mm for the exhaust when the engine is cold.
To adjust the idle speed, locate the idle adjustment screw near the carburetor or throttle body and turn it to achieve an idle speed of about 1700 ± 100 rpm.
If the headlights are not working, check the bulb condition, fuses, and wiring connections. Replace any blown bulbs or damaged fuses, and repair any faulty wiring.
To improve fuel efficiency, ensure regular maintenance, keep tires inflated to the correct pressure, avoid aggressive acceleration, and remove unnecessary weight from the scooter.
