Abnormal Noise from the Fan Area of a Scooter Motorcycle?
1 Answers
Reasons for abnormal noise from the fan area of a scooter motorcycle: 1. It might have sucked in foreign objects. It's best to disassemble and clean it, as prolonged exposure can damage the fan blades and affect heat dissipation. 2. The noise might originate from the rear wheel. Tightening the central axle screw of the rear wheel can help. An increase in gearbox noise is caused by gear wear. The noise could be due to debris inside the fan and the shroud causing a scratching sound, or it might be a hissing sound from the magneto and coil or the ignition sensor. Additionally, there could be a thumping sound caused by wear on the crankshaft bearing.
