Hey fellas, so I stumbled on this question when I picked up a paper air filter for my 12H-T 'Cruiser:
Long story short, I have a thin Unifilter (read: oiled) foam sleeve that slips right over the paper filter. I figured it would be nice to have two levels of filtration.
Is this approach recommended, or no? Do you reckon that the transfer of filter oil through the paper filter would screw things up too much?
