Cleaning the Air Filter

  1. Remove the filter from its cage. Inspect for any tears or damage–replace if necessary. The FC250-FE has a precision fit; always use a filter that matches the airbox profile.
  2. Wash the filter using air filter cleaner or mild dish soap. Gently squeeze (do not wring) out dirt and oil. Rinse thoroughly until water runs clear.
  3. Let it air dry completely. Never use compressed air or excessive heat, which could damage the foam.

Oiling – Re-Oiling the Air Filter

  1. Once dry, apply air filter oil until the entire surface is evenly coated. Massage oil throughout the foam so no dry patches remain. On the FC250-FE, thorough oiling is critical because the airbox sits close to intake ports, and fine dust can bypass a poorly oiled filter.
  2. Install the filter on the cage, making sure the seal is intact. Use a thin layer of air filter grease around the sealing edge for added protection against dust ingress.

Reinstalling the Air Filter

  1. Check the air box for any residual dirt and clean it with a damp towel or mild cleaner.  Avoid spraying water directly into the intake tract.
  2. Fit the filter and cage assembly back into the airbox. Listen for the distinctive clicking sound of the quick-release tab engaging, verifying a tight seal.
  3. Replace the right side cover, making sure it snaps securely in place without pinching the filter edge.

When to Replace the Air Filter

  • Inspect after every ride in dusty or wet conditions.
  • Replace the filter if torn, deformed, heavily clogged, or if it no longer fits tightly against the airbox seal. Always keep at least one spare filter on hand for quick swaps at the track or trailhead.
