It is recommended to use a high-quality 4-stroke motorcycle oil with a viscosity of 10W-40 for optimal performance.
The oil should be changed every 50 hours of operation or once per season, whichever comes first.
The recommended tire pressure is 5 psi (34.5 kPa) for both front and rear tires.
Check the battery charge, inspect the spark plug for wear or fouling, and ensure the fuel is fresh and the fuel lines are clear.
Regular maintenance includes checking the oil, coolant, and brake fluid levels before each ride, and performing a comprehensive inspection every 50 hours of use.
Loosen the rear axle nut, adjust the chain tensioner bolts until the chain has about 1 inch of slack, then retighten the axle nut.
Use an NGK DCPR8E spark plug, ensuring it is properly gapped to 0.7-0.8 mm.
Remove the air filter, wash it with warm soapy water, rinse thoroughly, let it dry, and apply a light coat of air filter oil before reinstalling.
Use a high-quality ethylene glycol-based coolant mixed with distilled water in a 50/50 ratio.
Consider upgrading the exhaust system, optimizing the jetting for your altitude, and ensuring regular maintenance is performed to keep the engine running efficiently.
