It is recommended to change the engine oil every 3000 km or every 6 months, whichever comes first, to ensure optimal performance and longevity of the engine.
Use unleaded petrol with an octane rating of 91 or higher for optimal performance and efficiency.
To adjust the chain tension, place the motorcycle on a center stand, loosen the rear axle nut, and adjust the chain adjusters on either side until the chain slack is about 25 to 30 mm. Tighten the axle nut once done.
The recommended tire pressure is 25 psi for the front tire and 28 psi for the rear tire when riding solo. Increase the rear tire pressure to 32 psi when riding with a pillion.
To improve mileage, maintain a steady speed, avoid rapid acceleration and hard braking, ensure regular maintenance, and keep the tires properly inflated.
Check the fuel level, ensure the kill switch is in the 'RUN' position, inspect the battery connection, and verify the spark plug condition. If issues persist, consult a professional mechanic.
The air filter should be cleaned every 3000 km. Remove it from the housing, gently clean it with compressed air or wash it with a mild detergent if it's a foam filter, and let it dry completely before reinstalling.
Regular maintenance checks include engine oil level, brake fluid level, tire pressure, chain tension, electrical system, and air filter condition.
Locate the idle adjust screw on the carburetor, and turn it clockwise to increase or counterclockwise to decrease the idle speed until the engine idles smoothly around 1300-1500 RPM.
Use a mild detergent and water, avoid high-pressure water jets, rinse thoroughly and dry with a soft cloth. Protect electrical components and lubricate moving parts after washing.
