What are the effects of a dirty air filter on a scooter?

[CalvinFitz]

A dirty air filter on a scooter can lead to severe clogging of the filter pores, obstructed engine air intake, insufficient air supply, and incomplete combustion of gasoline. This results in increased fuel consumption, black smoke from the exhaust pipe, and insufficient engine power. Regular cleaning or replacement of the air filter is necessary. The function of an air filter is to purify the air supplied to the engine before it enters the combustion chamber, removing impurities such as dust and sand particles to ensure clean air enters the cylinder block combustion chamber while maintaining smooth airflow. Using a high-quality air filter effectively ensures vehicle performance, maintains power, saves fuel consumption, controls dust entry, and allows smooth airflow into the engine combustion chamber, thereby extending the service life of components like the cylinder block, piston, and piston rings. Under low-dust road conditions, clean the filter every 2,000 km and replace it every 12,000 km. In high-dust conditions, shorten the cleaning/replacement cycle. New viscous or oil-containing filters cannot be cleaned and must be replaced directly.
