Shop parts for a 2014 Kawasaki KLX110 Dirt Bike.

Maintaining a clean air filter is crucial for your 2014 Kawasaki KLX110. A clogged or dirty filter can cause engine bogging, reduced power, and premature engine wear, especially in dusty off-road conditions. Owners should inspect, clean, or replace the air filter at least every six months or after 50 hours of use, but more frequently if riding in extreme dust or dirt.

Accessing the Air Filter

  • Remove both side panels, the seat, and the shroud assembly using an 8mm t-handle and screwdriver.
  • Unscrew the air filter cover (three screws) to access the filter.
  • Block the intake tube with a clean rag before removing the filter to prevent dirt from entering the engine.

Cleaning the Air Filter

  • Remove the foam filter element carefully.
  • Wash the filter with a designated foam filter cleaner or a mild, biodegradable solution.
  • Gently rinse until all dirt and old oil are removed.
  • Squeeze excess water out—do not wring, as this can damage the foam.
  • Let the filter air dry completely before re-oiling.
  • Apply a high-quality foam air filter oil evenly, ensuring full coverage but not over-saturating, which can reduce airflow.
  • Inspect the filter for tears or deterioration. Replace if damaged.

Reinstalling the Air Filter

  • Slide the cleaned/oiled (or new) filter back into position.
  • Make sure the sealing surface is flush and secure for maximum dirt protection.
  • Replace air filter cover and all panels and seat.

Replacement Recommendations

  • The 2014 KLX110 uses a dual-stage foam filter designed to trap both large and small dirt particles for superior engine protection. Popular replacement options include Twin Air and UNI filters, both offering multi-stage foam construction.
  • Twin Air filters use bonded coarse and fine foam layers with a flame-laminated one-piece design, boosting filtration and airflow. This improves engine performance and lifespan.
  • UNI air filters use seamless dual foam layers, maximizing clean airflow and can be cleaned and reused indefinitely.

Model-Specific Notes

  • KLX110 (2014+) air filter access differs from older models. For pre-2009 bikes, only the left side shroud is removed. On 2014 models, both side panels, seat, and shroud assembly must be removed.
  • Always use foam filter oil—never standard engine oil or aerosol sprays, which may degrade foam and compromise filtration.
  • The KLX110 is designed for off-road fun but is susceptible to dirt ingestion—routine filter inspection and cleaning is essential.

Proper air filter maintenance on your KLX110 protects your engine, maximizes horsepower, and ensures reliable performance whether you race or trail ride.
