08 Dirt In Airbox

[sparkyz]

Hey, I was getting around to checking the air filter on my 08 for the first time and noticed that there is a little bit of dust in the air box after the air filter? Is there a known point of common leakage at all on these? I bought the bike new so this is the first time it has been opened. The filter looked like it was seated properly. The air filter isn't too dirty but will definitely be replacing it and probably put a little grease around the edges of the new one for good measure. Anything else you guys would recommend?

BUMP.


Dirt or dust on the clean side of the airbox is not a good sign. I, too, would like to know if there are any known issues with air filter sealing.

Also...
If you are using a K&N filter or other type of oiled gauze air filter, then dust on the clean side is expected. They do not filter well, and performance gains from "increased air flow" or "lower restriction" are marketing hype.

I think your issue may be a result of having the same filter in there for 5 years.

How many miles on that filter? I've found on most bikes about 5 to 6 thousand is about it before they start getting pretty filthy. Shouldn't be suckin dirt though, just starts plugging up and you lose power and throttle response.

Check the clean side of the filter for dirt penetration, if there is none then check the airbox seals. I have o-rings on my '07 that seal the lid onto the airbox and they do take a compression set.
