How to Remove, Clean & Replace the Air Filter

  1. Removal
    - Remove the seat using the quick-release bolts.
    - Locate the airbox on the left side of the frame.
    - Loosen the air filter wing nut and carefully take out the filter element, avoiding dirt spillage into the air intake.
  2. Inspection
    - Assess the foam for tears, cracks, excessive discoloration, or degraded seams.
    - If the foam is heavily soiled, torn, or the welded junction is compromised, replace it – MotoSport offers OEM and performance filters for your 2020 YZ250X.
  3. Cleaning
    - Fill a tub with an approved foam air filter cleaner solution.
    - Submerge the filter and gently knead (do not wring) the foam to remove old oil and dirt.
    - Rinse thoroughly with water until clear.
    - Allow the filter to air dry completely before re-oiling.
  4. Oiling
    - Pour Yamaha Genuine Foam Filter Oil evenly around the filter.
    - Massage the oil into the foam, especially the seams, ensuring full saturation but no dripping.
    - For GYTR performance filters, always use Yamaha's recommended oil to maintain multi-density foam integrity.
  5. Installation
    - Re-insert the dry, oiled filter into the airbox, observing proper orientation.
    - Tighten the wing nut securely without over-torquing.
    - Reinstall the seat.

Replacement Intervals & Model-Specific Tips

  • After every ride in dust, sand, or mud; otherwise, inspect after every second ride for leisure trail use.
  • The 2020 YZ250X is tuned for aggressive off-road riding–neglecting the air filter leads to rapid engine wear in harsh conditions.
  • The OEM GYTR filter's colored foam makes spotting embedded dirt easier than standard white foam, supporting more precise maintenance cycles.
  • Always use recommended filter oils and never substitute filter types not intended for the YZ250X's two-layer construction.
