Use a high-quality 4-stroke motorcycle oil, SAE 10W-40, that meets or exceeds the API service classification of SJ or higher.
It is recommended to change the oil every 3,000 miles or every 6 months, whichever comes first. Regular maintenance ensures optimal performance.
The recommended tire pressure is 4 psi for the front tires and 4 psi for the rear tires. Always check when the tires are cold.
First, check the battery for charge and connections. Ensure the fuel is fresh and the fuel valve is open. Inspect the spark plug for wear or fouling.
The recommended spark plug is NGK DR8EA. Ensure it is properly gapped to 0.024-0.028 inches (0.6-0.7 mm).
To adjust the carburetor, locate the air/fuel mixture screw and idle speed screw. Adjust the air/fuel mixture screw to achieve the smoothest idle, then set the idle speed.
Stop the vehicle immediately and let it cool down. Check coolant levels and ensure the radiator is clean. Inspect for any coolant leaks.
Regularly inspect brake pads for wear and replace if necessary. Check brake fluid levels and ensure lines are free from leaks or damage.
Remove the air filter and wash it with a mild detergent. Allow it to dry completely, then apply air filter oil before reinstalling.
Regular maintenance includes oil changes, air filter cleaning, brake inspection, tire pressure checks, and ensuring all bolts and nuts are tightened.
