Key Notes for the 2018 Honda CRF250LABS Owner
- This model's air filter cannot be cleaned with compressed air or solvents without degrading its performance—cleaning must be done carefully using appropriate methods only.
- The OEM filter is a washable, viscous-type element. Should you ride in unusually dusty or wet areas, increase inspection and cleaning frequency as needed.
- Replacement should be performed at intervals listed in your owner's manual or more often during off-road use.
Air Filter Access – Removal Procedure
- Turn off the engine and let it cool. Remove the seat by releasing the mounting bolt(s) underneath the tail section.
- Locate the airbox inside the frame beneath the seat.
- Undo the airbox cover screws; lift the cover gently to expose the air filter element.
- Remove the filter carefully to avoid debris falling into the intake.
Cleaning Your Air Filter
- If your filter is OEM viscous-type, do not use compressed air, gasoline, or harsh chemicals.
- Light dust can typically be tapped off or removed with gentle brushing.
- For aftermarket cotton gauze or foam filters approved for this model, follow manufacturer-specific cleaning and re-oiling instructions.
- Allow cleaned filters to dry completely before reinstallation.
Replacement Instructions
- Inspect the filter. Replace if torn, overly dirty, or according to maintenance intervals (consult the owner's manual for detailed schedule).
- Install a new or freshly cleaned and fully dry filter into the airbox, ensuring a perfect fit and complete seal along the edges.
- Reinstall the airbox cover and tighten screws. Verify that no tools or debris remain in the airbox area.
- Reattach the seat – confirm it locks securely in place.
