Unique Notes for 2024 Sherco 250SEFFAC Owners

  • Factory Twin Air foam filter is standard, featuring a flat foam sealing ring for maximum airbox contact and sealing. The filter acts as a breathable gasket, delivering increased airflow while trapping fine debris.– The pre-oiled design uses biodegradable filter oil for consistent coverage.
  • Sherco’s filter design ensures quick removal and fitment, so cleaning and swapping filters is fasteven during race pits or rides.
  • The 250SEFFAC frame’s airbox is optimized for minimal intake restriction. Pay special attention to proper airbox seal and filter seating after maintenance to maximize dust protection.

Tools – Supplies Needed

  • Latex/nitrile gloves
  • Clean towels
  • Foam-specific air filter cleaner (solvent or mild soap)
  • Bucket – warm water
  • Air filter oil (biodegradable recommended)
  • Spare clean air filter (optional for rapid swaps)

Step-by-Step Air Filter Cleaning

  1. Remove seat and locate airbox under rear subframe. Unclip or unscrew the filter cage (no tools required for most Shercos).
  2. Carefully pull out the foam filter, inspecting for excessive dirt, tears, or damage. Set aside the filter cage – avoid knocking any debris into the intake.
  3. Dirt bikes ridden in heavy dust, sand, or wet conditions require inspections after every ride. For lighter trail use, cleaning every 2–3 rides is sufficient.
  4. Fill bucket with warm water – add air filter cleaner or gentle dish soap. Submerge filter, gently knead and squeeze out debris, but never wring or twist which can tear fragile foam.
  5. Rinse filter thoroughly until water runs clear. Repeat as needed for stubborn dirt.
  6. Set filter on a clean towel – allow to air dry fully. Avoid direct sunlight and never use a hair dryer or heat gun.

How to Re-Oil and Reinstall

  1. Apply air filter oil evenly throughout the foam, working deep into the pores. Squeeze filter as needed to ensure full coverage but do not oversaturateexcess oil may restrict airflow.
  2. Inspect the sealing ring and entire filter surface for missed spots. For the 250SEFFAC, pay particular attention to the flat foam gasket which mates with the airbox rim.
  3. Reinstall filter onto the cage, confirm that all edges seat flush with the airbox perimeter. Reinstall seat.
  4. Start engine briefly to confirm proper fit and performance.
