I couldn't tell you how many bikes I've owned that have had K&N air filters installed by previous owners. Okay, it's actually three, but that's enough to warrant this thread. Friends of mine have had similar experiences as well.
Behind each of those air filters was a layer of grit in the airbox. The damn things do a terrible job of actually filtering air. Hold one up to the light - what do you see? Light! Those are gaps that dirt can pass right through, straight onto your valves, onto your cylinder walls, and the rest is history.
So seriously, stop putting this junk on your bikes unless you are running a race team, need every ounce of horsepower possible, and don't mind rebuilding your engine after every race. Stick to OEM or equivalent paper or oiled, multi-density foam filters for your street bikes.
