Filter Skin Instructions: 1. Oil your air filter thoroughly. 2. Mount the air filter on the filter cage. Take a paper on the outside of the filter and let the paper soak in excessive oil. 3. Put a DRY filterskin over the air filter. 4. Mount the air filter in to the air box and put the bolt through the filterskin and tighten the air filter. Tests: During optimal circumstances you can ride for several ours without changing your air filter. During tests for 30 minutes on a sand track showed that the air filter looked like you had been riding for 3 minutes! This is of course no guarantee, so try and test for yourself and see how your filter looks like. For best result: Wait as long as you can before you put on the filter skin. The idea with the filterskin is that it should be as dry as possible so the dirt “bounces” off. If the filterskin becomes wet of filter oil, the dirt will stick to it as a normal filter.
