When the engine heats up, the cap could come flying off and cause irreparable damage to the vehicle and injure the rider.

NOTE: If the filter foam becomes blocked with dust, resistance to the intake of air will increase, and this will cause a reduction in the power output and an increase in the fuel consumption. It is recommended to clean the filter foam every 5, 000 kilometres, following the steps below: - Unscrew the screws securing the filter box cover. Submerge the foam a number of times until it is perfectly clean. [. . . ] Do not replace the drain plug, but instead plug the drain hole with clean cloth.
