Though i have used K&N filters on cars , i have never tried one on a dirt bike , i guess it would depend on what type of riding you do , i have been riding on a real dusty track lately and have been struggling with dirt getting past the filter (2 stage foam filter) , i was actually using K&N Filter Oil and the dust was still getting thru , (on both inner and outer filter) , i am now trying other filter oils (No-Toil , Maxima , etc) trying to find a way to keep the fine dust out , that can eat the valves in these bikes when it happens frequently
With that said , No , i have not tried a K&N filter , but the thought is crossing my mind if i can't find a solution with the different oils to see if they work any better than the K&N oil does on a foam filter , as i have tried several different brand filters with no positive results with the fine dust getting past the filter , i like the K&N Oil because its water cleanup capabilities , just clean it in the bathroom sink (i'm single , so no one else to worry about yelling at me when cleaning stuff) and i'm done , i guess the No-Toil stuff is similar , but still messier than K&N oil to clean up
Not sure if anything i babbled about makes much difference for you , but to somewhat answer your questions , yes i tried and use the oil , but i have not tried their filter yet , "yet" being the key word here.............
