Shop parts for a 2010 Yamaha TTR110 Dirt Bike.

Maintaining the air filter on your 2010 Yamaha TTR110 is essential for optimal performance, engine protection, and longevity. The TTR110's air filter is designed for repeated cleaning and reuse, but should be inspected often, especially if you ride in dusty conditions or after several hours of use. Regular cleaning and proper oiling are critical to keeping dirt, sand, and debris out of your engine.

Tools & Supplies Needed

  • Phillips screwdriver
  • Air filter cleaner or mild soap
  • Air filter oil (foam filter specific)
  • Clean rag or towel
  • Latex or nitrile gloves (optional)

Accessing the Air Filter

  • Remove the right side panel/fairing to access the airbox. The panel is held on by Phillips head screws–be careful not to strip the plastic bolts or threads.
  • Once the cover is off, identify the foam air filter element inside the airbox. There may be multiple screws securing the airbox cover, including one at the back.

Removing the Air Filter

  • Cautiously pull the foam air filter element from the airbox, ensuring you do not tear the foam.
  • Inspect the filter for any signs of significant wear, holes, or tears–if the foam is compromised, replace the filter immediately.

Cleaning the Air Filter

  • Rinse the filter in warm, soapy water. Gently squeeze the foam; avoid wringing as this can cause damage.
  • Rinse thoroughly with clean water until all soap is gone.
  • If using a dedicated air filter cleaner, follow the product's instructions, ensuring all oil and debris are removed.
  • Allow the filter to air dry completely before re-oiling. Do not use compressed air, direct heat, or open flames for drying.

Oiling & Reinstalling the Air Filter

  • Once dry, apply a high-quality foam filter oil evenly, working it into the foam. This oil traps dust and grime.
  • Squeeze out any excess oil using disposable gloves. The filter should be damp but not dripping.
  • Clean out any debris from inside the airbox using a damp rag. Also check the airbox drain plug at the lower back–drain any collected water or oil.
  • Install the clean, oiled filter back into the airbox, ensuring it forms a proper seal on all sides to prevent unfiltered air from entering the engine.
  • Reinstall the airbox cover and side panel securely. Avoid overtightening screws to protect plastic parts.

When to Replace the Air Filter

  • Replace the air filter if you notice holes, tears, brittleness, or if the foam simply will not clean up well. An OEM replacement is recommended to ensure correct fit and filtration levels.
  • Even new filters need to be oiled before use. Never install a dry foam filter.

Model-Specific Tips: 2010 Yamaha TTR110

  • The TTR110 is engineered with a reusable foam filter. Its simplicity makes at-home maintenance straightforward. However, the side panel and airbox screws are made of lightweight materials, so take care not to overtighten and avoid damaging them.
  • Always check the airbox seal and drain plug. Dust can bypass a poor seal or clogged drain plug, potentially harming your engine.
  • If you ride in extremely dusty or wet conditions, inspect and service the filter more frequently–a dirty air filter is the number one cause of poor performance and premature engine wear.

Environmental & Safety Notes

  • Dispose of old filter oil and cleaner in accordance with local environmental regulations.
  • Store oiled filters in a clean plastic bag if preparing spares ahead of time.

Keep your 2010 Yamaha TTR110 running strong by making air filter cleaning a regular part of your maintenance schedule. A clean, properly oiled air filter is your engine's best defense.
