Air Filter Cleaning – Replacement Guide for 2020 GAS GAS EC250

Shop parts for a 2020 GAS GAS EC250 Dirt Bike.

The 2020 GAS GAS EC250 is built for high-performance enduro riding, which means its air filter endures tough environments. Keeping your air filter clean and properly maintained is essential to preserve power, prolong engine life, and ensure your dirt bike performs at its best. Below you'll find a detailed, MotoSport-exclusive cleaning and replacement guide tailored for this model, plus insights unique to the EC250.

Unique Considerations for the 2020 GAS GAS EC250

  • Quick-Change Air Filter System: The EC250 utilizes a tool-free air filter system, making filter access especially easy compared to some competitors. You can remove and install the filter quickly—an advantage for both regular maintenance and race day filter swaps.
  • Foam Filter Guidelines: The EC250 filter is foam-based. Do not use fuel or petroleum cleaners, which can degrade the foam. Always rely on dedicated air filter cleaning solutions for this purpose.
  • Airbox & Water Resistance: Pay attention to sealing surfaces when re-installing—any gaps can let dirt or water into the intake. The high placement of the airbox offers some extra moisture resistance, but thorough installation is key.

When to Clean or Replace Your Air Filter

  • Check before every ride in dusty or muddy environments.
  • Clean the filter every 1–2 rides in dry, powdery conditions.
  • Replace the filter at least once per season, or sooner if damage or persistent staining occurs.

Step-by-Step: Cleaning the Air Filter

  1. Remove the Seat and Side Panel: Release the seat and remove the right side panel to expose the airbox.
  2. Remove the Air Filter: Unclip the air filter cover and carefully remove the filter assembly. Avoid dropping debris into the intake.
  3. Pre-Clean: Knock off loose dirt, then inspect for tears or deterioration.
  4. Wash the Filter: Submerge in a proper foam filter cleaner or mild soapy water. Do not use gasoline or harsh chemicals. Gently squeeze (never wring) to expel dirt. Rinse with clean water until residue-free.
  5. Dry Completely: Let the filter air-dry fully. A dry filter ensures oil will absorb evenly.
  6. Clean the Filter Cage: Wipe down the cage, ensuring all old oil and dirt are removed.
  7. Apply Air Filter Oil: Once dry, work air filter oil evenly through the foam, covering every pore. Squeeze out any excess to avoid oil dripping into the airbox or swingarm.
  8. Reinstall the Filter: Fit the filter carefully onto the cage, ensuring prongs and tabs are properly aligned and that the sealing edges contact the cage evenly.
  9. Inspect and Seal: Before reinstalling the cover, check for debris inside the airbox, then reinstall all covers and seat securely.

Replacing the Air Filter

  • If the filter is torn, notably degraded, or cannot be cleaned adequately, replace it with a genuine or high-quality equivalent foam filter.
  • Follow installation steps as above, being mindful of sealing and fit.

Pro Tips – 2020 GAS GAS EC250

  • Carry a spare, pre-oiled filter in a sealed bag for rapid swaps during long rides or races.
  • Apply a thin film of waterproof grease to the filter lip for improved sealing in extreme dust or water crossings.
  • Filter skins can help further extend cleaning intervals for riders in sand or heavy dust conditions.
  • The tool-free design of the EC250 means no excuses for skipping maintenance – always inspect your filter.

With regular cleaning and timely replacement using these steps, your 2020 GAS GAS EC250 will breathe easily and perform at its peak, no matter the riding conditions. Trust MotoSport for all your OEM and performance parts to keep your ride race-ready.
