Know Your Sherco 250SEFFAC Air Filter
- Type: The 250SEFFAC features a dual-stage, flame-laminated foam air filter. Premium versions, like the Twin Air and No Toil brands, use a coarse outer layer to block larger debris and a fine inner layer for finer particles, ensuring maximum protection and airflow for your engine.
- Fitment: Air filters for this model are precisely engineered for the 2020 Factory edition, ensuring proper sealing and fit in the airbox. Always use the correct filter to avoid dust bypass and engine damage.
- Flame Retardant: Leading replacement filters have a flame-retardant element, which is important for high-heat enduro riding and protects your bike against backfires.
When to Clean or Replace Your Air Filter
- After Every Dusty Ride: Off-road and enduro conditions quickly clog filters with dust and debris. Check after every ride and clean or replace as needed.
- Heavy Mud/Sand: If riding in wet, muddy, or sandy conditions, inspect and service your filter even more frequently.
- Replacement Interval: Even with regular cleaning, replace your filter every 20–30 hours of riding, or sooner if damage (tears, glue separation) occurs. Keeping a spare ready is recommended for quick swaps.
How to Clean the Air Filter
- Remove the Seat – Airbox Cover: Using the quick-access seat release, remove the seat and unscrew the airbox cover giving you full access to the filter.
- Remove the Filter: Gently pull the filter cage and filter away from the airbox. Inspect the sealing edge and the cage for dirt or damage.
- Pre-Clean: Use rubber gloves to tap out loose dirt. Avoid banging the filter hard to prevent foam damage.
- Wash: Clean with air filter-specific cleaner or mild dish soap in warm water. Massage gently. Avoid gasoline or harsh solvents—these break down the foam and glue.
- Rinse – Dry: Rinse thoroughly until water is clear. Gently squeeze (don't twist) water out, then let air dry naturally. Do not use compressed air or heat.
- Inspect for Damage: Look for holes, tears, or deteriorated seams. If any are found, replace the filter immediately.
- Oil the Filter: Once dry, apply foam air filter oil evenly, working it in for 100 percent coverage. Pre-oiled filters should still be checked and touched up if dry.
- Reinstall: Make sure the filter is properly aligned on the cage and that the sealing ring seats perfectly. Carefully reinstall the assembly in the airbox without letting dirt fall in.
- Final Check: Wipe down the edges of the airbox and make sure there's no dirt inside before mounting the airbox cover and seat.
Replacing the Air Filter
- Simply reverse the removal steps above to install a new filter. Always apply a thin layer of fresh, foam filter oil unless it's a pre-oiled replacement.
- Tighten the filter cage bolt and reseat the airbox cover to ensure a dust-tight fita crucial step with the fine tolerances on the Sherco 250SEFFAC.
