Finally gotten round to having a look into snorkel removel. I've taken the panel off the side of the bike where the air box is and there's some oily residue there, I'm assuming that's from the filter itself, is it something to worry about?

I'm going to hoover the dust/dirt off the filter itself, and I'm also thinking of applying some of that protective oil I've got from my open air K&N car filter?

Any thoughts chaps/lasses???
