Shop parts for a 2020 Honda CRF250LABS Dirt Bike.

The 2020 Honda CRF250LABS is engineered for maximum dependability on and off the trail, but to keep performance at its peak, regular attention to the air filter is essential. This model is equipped with a viscous type air cleaner element, which makes proper maintenance a little different compared to older foam filters.

Understanding the CRF250LABS Air Filter

  • Type: Viscous, non-foam filter that is designed to trap dust and debris effectively while allowing sufficient airflow for the 250cc fuel-injected engine.
  • Cleaning Constraints: This viscous element cannot be serviced with compressed air or solvent cleaning methods. Attempting to do so may degrade performance and shorten the air filter's lifespan.
  • OEM Fit: Always use filters that are an exact fit for your CRF250LABS to ensure maximum protection and engine life.

When to Service or Replace the Air Filter

  • Inspection: Inspect your air filter every 600 miles or more often if riding in dusty or muddy conditions.
  • Replacement Interval: Replace the air filter element according to the service manual's recommendation or whenever you notice excessive dirt, visible wear, or a reduction in power.

How to Remove the Air Filter

  1. Turn off the engine and allow it to cool.
  2. Remove the seat using the release latch underneath.
  3. Take off the right side cover; this exposes the airbox and the filter inside.
  4. Carefully lift the air cleaner element straight out; avoid dropping dirt into the airbox.

How to Inspect – Clean the Filter

  • Do not use compressed air or attempt to wash the viscous filter element with water or solvent. Instead, tap the filter gently to loosen loose dirt.
  • If the filter is excessively dirty, darkened, or cannot be cleaned simply by tapping, replace it promptly.

Installing a New Air Filter

  1. Confirm the new element is correct for the 2020 CRF250LABS.
  2. Insert the new element carefully into the airbox, ensuring a tight seal around the edges.
  3. Reinstall the right side cover and the seat, confirming both snap securely into place.

MotoSport Expert Tip for 2020 CRF250LABS Owners

  • The viscous air filter system used on the 2020 CRF250LABS is unique compared to standard foam units. Maintenance with the proper replacement part is critical for preserving fuel injection performance and engine durability.
  • The CRF250LABS's air filter provides optimal protection against fine dust & deep river crossings, but frequent inspection is especially important if you ride in silt- or sand-heavy environments.
  • Avoid aftermarket oiling or solvent cleaning products not specifically rated for viscous elements; these can hamper performance.
