Accessing the Air Filter

  • Remove both side panels, seat, and shroud assembly.
  • You will need an eight millimeter T-handle or socket & a standard screwdriver.
  • Unscrew the three bolts holding on the air filter cover and remove it to access the filter.
  • Plug the intake tube with a clean rag to prevent dirt from falling inside while you work.

Cleaning the Stock Foam Air Filter

  • Gently remove the filter for inspection. If it is visibly torn or heavily stained, replace it.
  • Wash the filter with foam filter cleaner or mild dish soap and warm water. Squeeze – do not twist – to avoid tearing the foam.
  • Rinse completely and let the filter air dry away from direct sunlight or heat sources.
  • Once dry, apply high quality foam filter oil evenly throughout to trap dust and dirt effectively.
  • Check the sealing ring. It should be flat and intact, ensuring no air bypasses your filter.

Replacement Frequency – When to Swap Filters

  • For normal riding: clean every six months or after 50 hours of riding.
    If you ride in dusty conditions, inspect and clean the filter more often.
  • If filter foam is sagging, torn, or refuses to clean up – replace it.
  • Replacement filters designed for the 2011 KLX110 include two-stage options, maximizing filtration and engine protection.

Install the Filter

  • Insert the clean – oiled filter carefully. Ensure it seats flat and seals securely against the airbox surface.
  • Replace the cover and securely fasten all screws.
  • Remove the rag from the intake tube to finish.

Important Model-Specific Notes

  • The 2011 KLX110's airbox allows easy access and quick filter swaps with basic hand tools. This is ideal for field service.
  • Dual-stage foam filters (like Twin Air) enhance filtration for small and large particles, ensuring your engine's safety without sacrificing airflow. Look for flat, thick sealing rings for the best airbox contact.
  • Replacement air filters manufactured for 2002–2025 KLX110 models are compatible, offering upgrades for competition and heavy-duty use.

Proprietary MotoSport.com Tips

  • Check seal integrity at each cleaning – never use a filter that doesn't fit perfectly.
  • Use only recommended foam filter oil – never substitute with engine oil or heavy oil types.
  • Inspect the airbox cavity for debris or standing water during service. Wipe dry before reinstalling your filter.
