Shop parts for a 2018 Kawasaki KLX110 Dirt Bike.
The 2018 Kawasaki KLX110 is built tough for trails and beginner riders, but keeping its small-displacement engine running strong demands regular air filter care. Properly cleaning – or replacing – your air filter prevents dirt and debris from entering the engine and preserves throttle response, power, and long-term reliability. Below is MotoSport's exclusive, step-by-step guide to air filter maintenance that addresses the unique features and access points of the 2018 KLX110.
Why Air Filter Maintenance Is Critical
- Dirt and dust directly affect engine life – A clogged or dirty air filter robs your engine of performance and may cause expensive internal damage if neglected.
- CRF110-style Side Access – The 2018 KLX110 air filter is accessible from the left side, behind the side panel and seat, making maintenance straightforward but essential for off-road conditions.
How Often Should You Clean or Replace?
- Standard recommendation: Every 6 months or every 50 hours of use, whichever comes first.
- For dusty riding conditions: Inspect and clean the filter after every few rides as fine dust can choke even a new filter quickly.
Required Tools & Products
- 8mm socket or T-handle wrench
- Phillips head screwdriver
- Mild detergent or dedicated filter cleaner
- Foam filter oil (not motor oil)
- Clean water and a lint-free rag
- Optional: Filter-specific protective screens for harsh conditions
Remove the Air Filter
- Remove both side panels using the 8mm socket.
- Remove the seat to gain access to the airbox.
- Unscrew and remove the airbox cover (typically three screws).
- Stuff a clean rag gently into the intake to block debris from entering.
- Slide the air filter carefully out of the airbox.
Cleaning Process
- Inspect the filter foam for tears, rips, or excessive wear—replace if damaged.
- Rinse the filter in warm soapy water; squeeze gently, do not twist or wring to avoid tearing.
- Repeat rinsing until water runs clear; avoid using harsh solvents.
- Let the filter air-dry completely—do not use compressed air or heat sources.
- Once dry, apply foam filter oil evenly. Massage the oil into the foam for full coverage.
- Wipe out the airbox with a clean, slightly damp rag or mild cleaner while the filter dries.
Reinstallation
- Remove the temporary rag from the intake opening.
- Slip the oiled (or new, if replacing) filter back into the airbox, seating it securely all the way around for a perfect seal.
- Reinstall the airbox cover and secure with screws.
- Reinstall the seat and side panels.
Special Notes for the 2018 KLX110 Owner
- KLX110-specific fit: Always use filters intended for KLX110 models years 2010 and up for proper sealing.
- Protective screens or filter covers can add another layer of defense in muddy or sandy environments.
- Rider tip: Carry a spare pre-oiled filter for long or especially dusty rides to speed up pit stops.
Kawasaki KLX110 engines are reliable, but clean air is their best defense against premature wear. Adhering to this guide ensures you get the most performance – and enjoyment – out of your ride, every time.
