  1. Access – Remove the Filter
    Switch off your WR250HQ. Remove the seat to access the airbox. Unscrew the air filter retaining bolt and gently pull out the air filter, taking care not to let debris fall into the intake tract.
  2. Inspect
    Visually examine the air filter for tears, holes, or severe wear. If damage is found, replacement is mandatory for safe riding.
  3. Wash
    Submerge the filter in a dedicated air filter cleaner solution. Gently massage the foam with your hands to remove dirt. Never use gasoline or harsh chemicals that could degrade the foam.
  4. Rinse
    Rinse thoroughly with tap water until the cleaner and dirt are fully removed. Squeeze (do not wring) out excess water.
  5. Dry
    Let the filter air-dry naturally; avoid direct sunlight and heat sources to preserve foam integrity.
  6. Oil – Reapply Filter Oil
    Generously apply air filter oil, ensuring uniform coverage. Massage oil into the foam to trap microscopic particles and improve engine longevity.

    Confirm the filter is completely dry and oiled. Insert back into the airbox, secure with the retaining bolt, and ensure a snug seal to avoid air leaks.
