Drying Twin Air BIO Filter

TIP: Oiling the filter without allowing it to dry sufficiently will trap some of the moisture.

4. Oil the filter

Soak filter in BIO Liquid Power Filter Oil, making sure to saturate the entire filter, coating the filter uniformly. Be sure to apply oil to the inside and outside of the filter.

TIP: Don't oil your air filter right before riding. Preoil the filter at least 24 hrs before riding to allow the oil to evenly penetrate the pores and allow the thinning agent to evaporate. A recently oiled filter will cause rich conditions.

5. Squeeze excess

Squeeze excess oil out of the filter so that a light coat of oil remains. Continue to massage until the filter is evenly coated.

7. Install the filter

Install the cage into the filter and install filter into airbox. Before installing check carburetor boot for dirt.

6. Dry the filter

Leave the filter out to dry in a well-ventilated area, preferably outside in the open air under a piece of cloth. After approximately 2 hours, the filter is ready to be used. Store pre-oiled filters in the resealable Twin Air bag (or an airtight plastic bag) and in a dark spot.
