Auto Zone has the breather filters. Get the stainless or they will rust in a few years. Cut the rubber fitting out of them, add double sided tape, and apply. Had them on my Valk for 8 yrs or more. Some are still the original ones. They do get loose from time to time but I push them back on or add new tape. Be sure to tell them chics at the bikini bike washes to stay away from them. They'll knock them off with a rag. Had one come up, after told her to watch them, and said, 'uh this fell off'. No prob. Stuck it back on and I'll be cursed if it didnt fall off I-90.

Only one I ever lost. It has been thru some winds and mansoon rains.
Oh, their $8-9 a pc.
