Maintaining the air filter on your 2020 Kawasaki KLX140G is one of the most crucial steps to keep your engine running strong. MotoSport.com brings you this proprietary guide, specifically tailored to the KLX140G, to help you get the best performance and longevity from your dirt bike. Unique to this model, the KLX140G features an accessible airbox and filter system, ideal for quick cleaning and replacement—perfect for riders seeking both reliability and ease of maintenance.
Service Intervals – Why It Matters
Kawasaki recommends cleaning your air filter after the first five hours or one month of use, then after every 50 hours or six months. If you ride in dusty, dirty, or wet conditions, service the filter more often. Always replace the filter if you see any damage or deterioration, as a compromised filter can reduce engine life dramatically.
Tools & Materials Needed
- High-quality foam air filter oil
- High flash-point solvent
- Lint-free towels
- All-purpose grease
- Clean, damp rag
- Flat/Phillips screwdriver (as required for covers or bolts)
Removal – Step-by-Step
- Remove the left side cover and air box cover.
- Unscrew and remove the wing bolt holding the air filter in place.
- Carefully take out the air filter and separate it from its frame.
- If accessible, gently stuff a lint-free cloth beyond the filter area to prevent debris from entering the intake (KLX140G's design may block direct carb access; just take extra care to avoid dirt entering the clean zone).
Cleaning the Filter
- Gently clean the inside of the airbox with a damp rag.
- Wash the foam element in a bath of high flash-point solvent. Avoid aggressive wringing, which can tear the foam—instead, gently squeeze it dry with a towel.
- Inspect for damage. Any wear, holes, or hardening means it's time for a new filter.
Oiling the Filter
- After it's fully dry, apply filter oil evenly through the foam. Massage the oil gently to cover entirely but do not over-saturate. The entire filter should feel tacky but not dripping.
- Wrap in a clean towel and gently squeeze to soak up excess oil.
Reinstallation – Tips for a Perfect Seal
- Apply all-purpose grease to all connections, contact points, and the lip of the filter to guarantee a solid seal, preventing unfiltered air from bypassing the filter.
- Reassemble the filter to its frame and align carefully in the airbox.
- Tighten the wing bolt snugly; the plastic spacer in the KLX140G has a flat side that should face outward for the proper fit.
- Reinstall the airbox and side covers.
Key Notes for KLX140G Owners
- The KLX140G's air filter is robust but must be cleaned and oiled frequently in dusty environments—Neglecting maintenance can lead to engine wear or performance loss unique to this air-cooled, mid-sized off-roader.
- Always inspect the seal between filter and airbox; a poor seal can lead to distinctive engine noises and unfiltered air entering the engine.
- KLX140G's airbox configuration gives ample space but take care when reinstalling to avoid pinching or improper fit.
