How to Change a Kawasaki KLX 110 Air Filter
A new air filter improves performance on a Kawasaki KLX 110 dirt bike, and it's an important gatekeeper that prevents contaminants from getting sucked into the engine.
On the trail, dust and other contaminants can choke your bike's engine and chip away at horsepower. You might not need to replace your air filter, only clean it. Watch the video above or follow the steps below to learn how to clean and/or change the air filter on a Kawasaki KLX 110 dirt bike.

Tools and Parts - Kawasaki KLX 110 Air Filter Change
- Phillips head screwdriver
- Pliers
- 8mm socket
- Ratchet
NOTE: Depending on the condition of the air filter, you either need to clean or replace it. If you're just going to clean the air filter and put it back in the machine, you'll only need the cleaner spray and filter treatment.
Kawasaki KLX 110 Air Filter Change - Plastics Removal
Step 1. Remove two of the three 8mm bolts holding the plastic in place on either side of the machine.
NOTE: Removing the third 8mm bolt comes later.
Step 2. Lift the back of the seat and push the front of it down to clear it from its latch and remove it.
Step 3. Take the plastic pieces below the seat on either side off. Pull the back of the plastic away from the frame, then slide the plastic forward to unhook it from the front shroud.
Step 4. Remove the third 8mm bolt on either side underneath where the plastics were hooked.
Step 5. Remove the Phillips screw located on the center of the fuel tank area, just below the fuel fill cap, and lift off the shroud.
Kawasaki KLX 110 Air Filter Change - Removing the Old Air Filter
Step 1. Locate the air box on the left hand side of the machine, and remove the three Phillips screws to open the box and expose the air filter.
Step 2. Remove the air filter.
NOTE: If your Kawasaki dirt bike has a reusable air filter, you can clean it and pop it back in or replace it altogether if it's torn. If you're going to clean the current air filter, make sure there are no tears that will allow dirt to get past the filter into the engine.
Kawasaki KLX 110 Air Filter Change - Cleaning the Air Filter
Step 1. Liberally spray foam air filter cleaner on both sides of the filter. Make sure you spray both sides and get a nice coating that soaks into the filter.
Step 2. Wait about 15 minutes while the spray works off loose dirt and other contaminants. Then, knead the filter in a bowl of water to work the dirt out. If the air filter is dirty, you'll see the water turn cloudy. Wring the filter out when you're done.
Step 3. Wait for the filter to dry completely.
NOTE: It may take hours for the air filter to dry completely, but don't put the filter back in while it's still wet, as this will create more problems.
Step 4. Treat the dry filter with a light coating of foam filter oil spray on both sides, then knead it in.
Kawasaki KLX 110 Air Filter Replacement
Step 1. Find the two openings in the air box. Check inside the openings for any dirt or debris inside and use a rag to remove any that's present.
PRO TIP: We used brake/contact cleaner to tidy up our intake, using a rag to cover the bottom opening. If you use brake cleaner, wear eye protection.
Step 2. Look underneath the air box for a small plastic reservoir. It's about the size of your thumb and catches water that's drained from the air box. Use pliers to squeeze open the clip, then remove it, dump it out, wipe down the inside and put it back on the machine.
Step 3. Install the new air filter in the same way the old one was placed (the only way, by its shape).
Step 4. Inspect the seal around the air box lid for cuts, then replace it and tighten the three Phillips head screws that hold it in place.
Step 5. Reinstall the plastics onto the bike and you're done.
