After removal, check to see if the foam filter is blocked, in which case wash in paraffin, apply some air
filter foam oil then squeeze the filter material between your hands to remove surplus oil. Do not wring out
the filter element, as this will damage the foam. When refitting the air filter sure that the foam fits the box
correctly so that no air can enter the engine without being filtered. It must be cleaned more frequently if
the mortorbike is used in humid or dusty places.
ATTENTION: The filter must be cleaned after each exit.
