Paper tends to soak up water, then doesn't let the air through any more. Nothing wrong with the standard element. Only thing wrong is the breather drips on the element, eventually soaking it with the water/oil mixture which comes out of the breather, thus sabotaging the filter element. Take breather pipe off air filter housing and direct into a bottle, can, or your rear chain, clean the filter element or replace it (but not with a pirate one- see [Broken Link Removed]), and everything will be fine.
