How to clean and oil
your foam air filter

• When should you clean your foam filter ?

For off-road, motocross, enduro or supermoto use, it is recommended to clean the filter after each ride. For the rare road bikes that are equipped with foam air filters, we advise you to clean it regularly, every 5,000 km maximum.

• When should you change your foam filter ?

You need to change your foam air filter every 50,000 km or so. In off-road use, check the state of the foam after each wash.

To access the air filter you usually need to disassemble the seat, side cover or tank cover. You can probably find this information in the manufacturer’s manual.

Unscrew or unclip the air filter. We recommend putting on a filter cover to prevent impurities from falling into the intake sleeve.

Once disassembled, remove the filter from its cage and place it in a clean tray.

Pour some Air Filter Cleaner in the tray and then soak the air filter foam in several times. Air Filter Cleaner effectively removes all impurities (dust, mud, sand, oils) without damaging the foam.

For the last rinse, clean the tray and pour some clean air filter cleaner. Be careful not to go to the bottom of the tray all the impurities will be there!

Squeeze the air filter to avoid damaging it. Let dry for about 2 hours in a ventilated room.

Once the air filter is dry, take a clean tray and pour a few centimetres of air filter oil into it.

Put some gloves on and dip the air filter in the liquid. Knead it still without twisting it. It must be a 100% soaked. As our liquid is blue, it is easy to check that the oil is evenly distributed over the whole filter.

For those who do not like to get dirty, you can use Air Filter Oil Spray. Its diffuser allows an easy application thanks to a wide and homogeneous spray. Be careful to spray the inner and outer parts of the filter.

Once you're done and the filter is well greased, press it to remove the excess oil.

Let it dry for a few minutes on paper towels.

While you're at it, clean the cage and screw. Also check that the intake sleeve is perfectly clean and, if necessary, clean it as well.

If you do extreme enduro in a very humid environment apply a thin layer of Waterproof Grease on the front of the filter before reassembling it to prevent water from flowing between the filter and the intake sleeve.

And if you ride in the sand, we recommend putting a sock on the filter for a better protection.

When reassembling the air filter on the bike, make sure that the filter is very well positioned in its original location, that the screw or clip are well tightened and positioned so that the filter can perfectly stop all impurities.

You can check the appropriate positioning in the manufacturer’s manual.

Once your air filter is in place, put the saddle, side cover or tank cover back on.

And we're done ! It wasn't that hard !
