Yamaha YFZ05YYXN 50 2022 Owner's Manual

The recommended oil type for the Yamaha YFZ05YYXN 50 2022 is Yamalube 4, 10W-40 or any equivalent motor oil meeting API service SE, SF, SG, or higher.
It is recommended to change the oil every 6 months or every 600 miles, whichever comes first, to maintain optimal engine performance.
The ideal tire pressure for the Yamaha YFZ05YYXN 50 2022 is 15 psi for both front and rear tires. Always check the pressure when the tires are cold.
To adjust the chain tension, loosen the rear axle nut, then adjust the chain adjusters evenly on both sides until the chain has about 1 inch of slack in the middle. Tighten the axle nut after adjustment.
Check the battery terminals for corrosion and ensure they are tight. If the bike will not be used for an extended period, disconnect the battery and store it in a cool, dry place. Use a trickle charger to maintain charge.
If the bike does not start, check the fuel level, ensure the kill switch is in the "run" position, and inspect the spark plug for wear or damage. If the issue persists, consult a professional mechanic.
Regular maintenance includes checking and changing the oil, inspecting brakes and tires, lubricating the chain, checking coolant levels, and ensuring all bolts and nuts are properly tightened.
Remove the air filter cover and take out the air filter. Clean it with a mild soap and water solution, allow it to dry completely, then apply air filter oil before reinstalling it.
If the bike overheats, stop riding immediately and let the engine cool down. Check coolant levels and inspect for leaks. Ensure the radiator fins are clean and not obstructed. Consult a mechanic if necessary.
To improve fuel efficiency, ensure regular maintenance is performed, keep tires inflated to the recommended pressure, avoid aggressive acceleration, and use the recommended grade of fuel.
