What You Need

  • Dual-stage foam air filter (OEM or quality aftermarket such as Yamaha/GYTR, No-Toil, or MOTOREX)–3–4–
  • Foam air filter cleaner
  • Foam air filter oil (preferably bottle, not aerosol)
  • Clean bucket (with lid recommended for storage)
  • Latex or nitrile gloves
  • Clean, lint-free towels
  • Lithium soap-based grease

How to Remove the Air Filter

  1. Place the bike on stable ground. Make sure the bike and surrounding areas are clean to prevent any debris from falling into the intake.
  2. Release the retaining clips or bolts securing the air filter cover.–5–
  3. Carefully remove the air filter and the sealing ring or guide. Inspect for tears, holes, or damage. If damaged, replace with a genuine Yamaha filter.

Cleaning and Oiling the Air Filter

  1. Rinse off excess dirt with warm water. Do not twist the filter when squeezing, as this may tear the foam.–2–
  2. Submerge the filter in foam air filter cleaner. Massage gently and agitate to loosen embedded dirt. Avoid harsh detergents or gasoline.
  3. Rinse thoroughly in clean, warm water. Squeeze (do not wring) to remove excess water.
  4. Allow the filter to air dry completely in a clean area.
  5. Apply foam filter oil evenly by massaging the filter. Use bottled filter oil for optimal penetration; aerosol sprays do not distribute oil as completely.–2–

Reinstallation

  1. Apply a thin bead of lithium soap-based grease to the sealing surface of the air filter to ensure a proper seal.
  2. Reinstall the air filter and sealing ring/guide. Secure the air filter cover firmly.
  3. Check that there is no gap between the filter and the air box to prevent dirt or water intrusion.

Replacement Tips

  • Inspect the filter every ride in especially dusty or muddy conditions. Consider carrying a spare, pre-oiled filter for race days or multi-hour off-road sessions.
  • Always install the filter with clean gloves to avoid introducing contaminants.
  • Replace the filter if you notice major wear, persistent staining, or tears in the foam.
