Hello Everyone, Going to install a new air filter in my 2009 XR. I haven't done it before, and I have a question. I saw on a K&N video that grease needs to be applied along the edge, I know they sell their own grease, but is there a certian type I can buy to use without ordering theirs? Also, I know installing this is a little more involved than a lot of other bikes, so any other tips would be appreciated. Thanks!
