Routine air filter maintenance is crucial for the 2023 GAS GAS EX350F to ensure optimal performance and engine longevity. This unique guide, brought to you by MotoSport.com, covers specific steps and insights tailored for owners of this high-performance enduro machine.

Why Air Filter Maintenance Matters

The EX350F's high-revving DOHC single produces substantial power and demands a clean, well-oiled air filter for consistent throttle response and protection from dust and debris. Neglecting this maintenance may result in a loss of performance and accelerated engine wear.

Recommended Cleaning – Replacement Interval

  • Inspect the air filter after every ride in extremely dusty conditions and at least every 10 hours of operation otherwise.
  • Replace the air filter whenever it shows signs of damage, excessive dirt, or after several cleanings per the manufacturer's schedule.

Tools – Supplies Needed

  • Lift stand or bike stand
  • 10mm socket or T-handle
  • Clean rags
  • Approved air filter cleaner (non-flammable, bike-specific recommended)
  • Air filter oil (foam filter oil)
  • Gloves

Removing the Air Filter on Your EX350F

  1. Place the bike securely on a stand.
  2. Remove the seat by pressing the rear latch and lifting upward—no tools required for this step on the 2023 EX350F.
  3. On the left-hand side of the airbox, unfasten the quick-release pin holding the air filter cage.
  4. Gently pull the air filter with its cage from the airbox, taking care not to shake debris into the intake tract.

Cleaning Instructions

  1. Gently remove the filter from the plastic cage.
  2. Use an approved cleaner to fully saturate the foam. Squeeze (do not wring or twist) the foam repeatedly until dirt and oil are washed out.
  3. Rinse thoroughly with clean water. Repeat as necessary.
  4. Allow the filter to air dry completely—do not use high heat or open flame.

Oiling the Filter

  1. Apply air filter oil evenly to the dry filter. Massage oil throughout the foam to ensure complete coverage.
  2. Gently squeeze out any excess oil.
  3. Wipe the air filter cage and mating surface in the airbox with a damp rag to remove any residual dust or dirt.

Reinstallation

  1. Seat the filter securely on the cage; ensure the gasket is undamaged and positioned properly against the sealing surface.
  2. Insert the loaded cage and filter assembly snugly back into the airbox, watch for correct alignment, and secure the pin.
  3. Reinstall the seat, confirming the latch clicks securely in place.

Features – Tips Specific to the 2023 GAS GAS EX350F

  • The EX350F uses a tool-free seat and air box access, making filter servicing particularly fast.
