The recommended oil type for the Yamaha YW125J Zuma 125 2018 is Yamalube 10W-40 or SAE 10W-40 with an API service grade of SG or higher.
It is recommended to change the engine oil every 2,000 miles or every 6 months, whichever comes first. Regular oil changes help maintain engine performance and longevity.
First, check the battery for charge and connections. Ensure the kill switch is in the 'run' position and the fuel valve is open. If these are in order, inspect the spark plug and fuel level. If issues persist, consult a mechanic.
Regularly inspect brake pads for wear and replace if necessary. Check brake fluid levels and top up with DOT 4 brake fluid as needed. Ensure brake cables and levers are functioning smoothly.
The recommended tire pressure for the Yamaha Zuma 125 is 29 psi for the front tire and 33 psi for the rear tire. Proper tire pressure ensures optimal handling and fuel efficiency.
Start by checking the battery connections and fuses. Inspect the wiring for any visible damage or corrosion. Use a multimeter to test electrical components such as the ignition switch and relays.
Yamaha recommends using a high-quality ethylene glycol antifreeze containing corrosion inhibitors designed for aluminum engines, ideally Yamaha's own coolant brand.
The air filter should be inspected every 4,000 miles and replaced if necessary. Dusty or harsh riding conditions may require more frequent changes to ensure optimal engine performance.
Check for any obvious issues such as low oil levels or loose fuel caps. If no obvious issues are found, it is advisable to consult a dealer or mechanic to diagnose and resolve potential engine problems.
Ensure regular maintenance such as timely oil changes, proper tire inflation, and clean air filters. Riding smoothly and avoiding rapid acceleration can also improve fuel efficiency.
