What Causes a Scooter to Lose Power?

[HarleyAnn]

Motorcycle power loss is usually caused by the following reasons: 1. The motorcycle may have been driven at high temperatures for a long time, meaning prolonged use of low gears; 2. Damage to the cylinder head gasket causing air leaks, resulting in insufficient pressure in the cylinder; 3. Poor quality gasoline, possibly containing too many impurities; 4. The throttle lever not returning to its position after being opened, remaining in a closed state. Here are the checks and repairs for motorcycle power loss: 1. Check if the air filter is clean: mainly inspect whether the filter element is clean. If it is covered with dust, it can be washed with soapy water, dried, and then reinstalled. 2. Check if the cylinder pressure is normal: you can unscrew the spark plug, press hard on the spark plug with your thumb, and then step on the starter pedal. If you can't hold it no matter how hard you press, then it is normal.
