Air Filter Cleaning & Replacement Guide for 2012 Kawasaki KLX110

Shop parts for a 2012 Kawasaki KLX110 Dirt Bike.

Maintaining the air filter on your 2012 Kawasaki KLX110 is essential for engine performance – a clean filter protects against dirt, optimizes airflow and keeps your bike running smoothly. The KLX110 uses a foam air filter engineered specifically to balance filtration and airflow, and regular maintenance is critical, especially in dusty riding conditions. Unique to the 2012 KLX110, gaining access to the air filter involves removing both side panels, the seat, and the shroud assembly. This updated design helps ensure a tight seal and reduces contaminants entering the engine compared to older models.

When to Clean or Replace Your Air Filter

  • Inspect/clean every 6 months or 50 hours of riding—clean more often in dusty conditions.
  • Replace the filter if it is torn, excessively grimy, or the foam shows signs of breakdown.

Tools & Supplies Needed

  • 8 mm T-handle or socket
  • Screwdriver
  • Dedicated air filter cleaner and filter oil
  • Clean rags
  • Replacement air filter if needed

Removing the Air Filter

  1. Remove both side panels using your tool of choice.
  2. Take off the seat, then the shroud assembly.
  3. Unscrew the air filter cover (three screws secure it).
  4. Place a clean rag into the intake tube to prevent debris from entering.
  5. Gently remove the filter element for inspection.

Cleaning the Foam Air Filter

  1. Tap filter gently to remove loose dirt.
  2. Wash the filter in a bath of air filter cleaner or mild detergent. Do not use gasoline – it can damage the foam and adhesive.
  3. Rinse thoroughly with clean water. Let dry completely.
  4. Apply foam air filter oil evenly, working it into every part of the filter. Oil ensures fine dust is trapped and enhances protection.
  5. Inspect for tears or signs of breakdown. Replace if damaged.

Installing the Air Filter

  1. Clean the inside of the air box to remove any residual dirt.
  2. Insert the oiled filter, ensuring a proper seal with the air box. The KLX110 uses a thick, flat sealing ring for maximum contact and to prevent dirt bypass.
  3. Reinstall the air filter cover, shroud assembly, seat, and panels in reverse order.

Key Notes for KLX110 Owners

  • The factory filter is dual-stage foam, combining coarse and fine layers for specific filtration and airflow needs.
  • Only use foam filter oil–KLX110's design depends on oil saturation for effective dust capture.
  • Take care not to over-oil, as excess oil can restrict airflow and lead to bogging.
  • If upgrading to aftermarket filters, look for those with bonded dual layers and robust sealing rings – like the Twin Air and Motorex filters designed specifically for KLX110 models.

Performance Tips

  • Increasing airflow with premium filters can enhance throttle response, but always ensure superior filtration to avoid engine damage.
  • Kawasaki's 2012 KLX110 airbox design offers improved protection and ease of maintenance over prior versions, making regular cleaning straightforward for owners.
  • Stock airbox removal is not recommended unless using a full aftermarket intake solution engineered for the KLX110.

A clean air filter is your KLX110's best line of defense—keep maintenance regular for lasting performance and reliability on every ride.
