Why is the scooter lacking power?

[DeAlessandra]

Scooter lacking power is usually caused by the following reasons: 1. The motorcycle may have been exposed to high temperatures, meaning it has been driven in low gear for an extended period; 2. Cylinder head gasket leakage, resulting in insufficient cylinder pressure; 3. Poor quality gasoline; 4. The throttle lever has not returned to its position and remains closed. Solutions: 1. Regularly replace and clean the carburetor. 2. When replacing spark plugs, choose high-quality products. 3. Grind the valves and replace the piston rings. 4. Promptly inspect and replace worn clutch plates, chains, or sprockets. 5. Have a professional carefully adjust the valves.
