cleaned with a specific filter foam cleaning solvent.
Once it has thoroughly dried, the filter may be reinstalled by follo-
wing the above instructions in the reverse order after prior lubri-
cation of the filter with special purpose filter oil. This is accomplis-
hed by applying a few drops of this oil and allowing to run so that
it is uniformly distributed. It may now be fitted in place, and care-
ful attention should be paid to achieving a perfect fit, otherwise
non-filtered air may enter and lead to serious damage. The air fil-
ter should be cleaned in accordance with the indicated periods of
time. It should be cleaned more frequently if the motorbike is used
in very dusty or humid environments.
