Air filter assembly for Viper 125-200 cc motorcycles and similar (China, Minsk). The air filter cleans the air before the carburetor and protects the cylinder from dust. The assembly includes the housing and the filter element.
Replace it if it is dirty, the filter material is torn or the housing is damaged. A clogged filter causes excess fuel consumption and loss of power, and a torn one lets dust through and speeds up wear of the piston group.
