The 2011 Yamaha TTR110 is a favorite among riders for its reliability and ease of maintenance. Keeping the air filter clean and well-maintained is crucial for optimal performance and long engine life. Below, MotoSport provides a comprehensive, step-by-step guide teaching you how to clean or replace the air filter on your TTR110, ensuring your bike runs at its best on every ride.
Why Air Filter Maintenance Matters on the TTR110
Unlike street bikes, dirt bikes like the TTR110 are frequently exposed to dust and debris, which can quickly clog or damage the air filter. A clogged filter restricts airflow, reducing power and potentially allowing dirt into the engine. Regular filter care is a hallmark of smooth rides and solid engine protection.
How Often Should You Clean or Replace the Air Filter?
Clean the air filter after each ride in dusty conditions, or every 5–10 hours of riding. In muddy or extremely dusty environments, increase the frequency. Replace the filter if it shows signs of tearing, hardening, or degradation; the foam element should be in good shape and fully flexible for reliable filtration.
What You’ll Need
- #2 Phillips screwdriver
- 8mm socket or driver
- Fresh air filter or air filter cleaning kit (oil & cleaner)
- Warm water and mild soap
- Nitrile gloves
- Clean rags
Air Filter Removal
- Ensure the engine is cool for safety.
- Remove the right side fairing to access the airbox.
- Use the Phillips screwdriver to remove the air filter cover screws. The TTR110 typically has three screws–top, bottom, and rear.
- Carefully pull off the air filter cover, then gently withdraw the filter element from the airbox.
Cleaning the Air Filter
- If reusing the filter, inspect for tears or excessive wear. Discard and replace if any damage is found.
- Rinse the filter in soapy warm water. Gently squeeze (do not wring or twist) the filter to release trapped dirt.
- Repeat the rinsing process with clean water until all soap and dirt are gone.
- Allow the filter to air dry completely.
- Apply air filter oil evenly to the dried foam. Massage the oil through the foam for full coverage–an oiled filter traps dirt effectively.
Replacing the Air Filter
- If installing a new filter, always oil it thoroughly as described above before installation.
- Clean the inside of the airbox and the gasket surface with a clean rag to ensure a positive seal.
- Insert the cleaned or new, oiled filter, ensuring a snug fit and complete contact around the edges for dust-tight sealing.
- Replace the air filter cover and secure with the screws. Avoid over-tightening, which can damage the threads or deform the airbox.
- Install the side fairing.
Special Notes for 2011 Yamaha TTR110 Owners
- The TTR110’s foam air filter is reusable, making cleaning especially important. Replace only when the filter is no longer structurally sound.
- Check the airbox drain plug at the lower back of the airbox for water or oil accumulation after washing or riding in wet conditions.
- Always use chemicals designed for foam air filters to avoid damage.
- Keep replacement screws and plastic components handy—the TTR110’s airbox plastics are durable but can strip if overtightened.
Environmental & Safety Tips
- Dispose of used cleaning or oiling chemicals responsibly–never pour them down household drains.
- Store extra filters and oil in a clean, dry area to avoid contamination between rides.
