Shop parts for a 2024 Kawasaki KLX300SM Dirt Bike.
The 2024 Kawasaki KLX300SM is an agile supermoto built for urban exploration – but to keep the engine performing at its best, regular air filter maintenance is essential. Dust and debris from city streets or off-road detours can quickly clog the air filter, reducing power and engine life if neglected. This MotoSport-exclusive guide takes you through the essentials of air filter cleaning and replacement, tailored specifically for the KLX300SM.
Why Air Filter Care Matters on the KLX300SM
- City and trail environments can expose your filter to high levels of dust, pollen, and debris, especially with aggressive riding styles.
- A clean air filter maximizes throttle response and protects the fuel-injected 292cc engine from harmful contaminants.
- Neglecting this service can cause poor performance, hard starting, and, over time, expensive engine damage.
How Often Should You Clean or Replace the Air Filter?
- Check the air filter every 600 miles (1,000 km), or more often if riding in dusty conditions. Clean as needed.
- Replace the air filter at least once a year or whenever you notice heavy contamination or filter wear that can't be cleaned out.
Tools & Supplies You Will Need
- OEM-style or aftermarket replacement air filter (MotoSport stocks both options)
- Air filter cleaning solvent or mild dish soap
- Bucket of warm water
- Air filter oil (for foam filters)
- Clean, lint-free towels
- Phillips screwdriver and 8 mm socket or T-handle (verify with your bike's toolkit)
- Gloves
Accessing the Air Filter on Your KLX300SM
- Turn off the bike and allow the engine to cool completely.
- Remove the seat by releasing the seat bolts with an 8 mm socket or T-handle (refer to your owner's manual if uncertain).
- Locate the airbox directly underneath the seat at the rear top of the frame.
- Loosen and remove the air filter cover bolts (typically Phillips head screws).
- Carefully detach the air filter and note its orientation for reinstallation.
Cleaning the KLX300SM Air Filter
- Gently inspect the filter for tears, holes, or degraded foam. Replace immediately if damaged.
- If the filter is intact, tap it gently to loosen loose dirt.
- Wash the filter in a bucket of warm water and mild dish soap or a dedicated filter cleaner. Submerge the filter and gently massage out dirt. Do not wring or twist the filter harshly.
- Rinse thoroughly with clean water until all soap and contaminants are gone.
- Allow the filter to air dry completely away from direct sunlight or heat sources.
- Once dry, apply air filter oil evenly throughout (if the filter is foam type; Kawasaki OEM uses foam). Work the oil in to fully coat the filter but avoid over-saturation.
- Squeeze out any excess oil. Blot with a lint-free cloth if necessary.
Reinstalling or Replacing the Air Filter
- Carefully reinstall the clean, oiled filter in the correct orientation.
- Ensure the filter is seated tightly to prevent unfiltered air bypass.
- Replace the airbox cover and secure with screws; do not overtighten.
- Refit the seat and secure its bolts.
Special Notes for 2024 KLX300SM Owners
- The KLX300SM's airbox design allows easy access, making regular service feasible even for new owners.
- Aftermarket reusable filters are available and may require different cleaning products – always follow the manufacturer's recommendations.
