Why Air Filter Care Matters

- Optimizes Power: A clean, well-oiled filter ensures maximum airflow and responsive throttle.
- Specific to the DRZ125L: The DRZ125L uses a washable foam-style filter that should always be thoroughly dried and adequately oiled before installation.
Tools & Supplies You'll Need

- Clean rags
- Air filter cleaner (mild dish soap or dedicated solution)

Step-by-Step Cleaning Guide
- Remove the seat: Undo the seat bolts and lift the seat off to expose the air box–DRZ125L's air filter is accessed under the seat and side cover.
- Remove side cover: Only one side cover generally needs to come off for access.
- Remove the air filter: Unscrew the retainer and carefully take out the filter. Take note of the plastic cagethis supports the filter and must be reinstalled correctly.
- Initial inspection: Check for excessive dirt, damage, or tears. Replace immediately if you spot any damage.

Cleaning:
Place the filter in your bucket/container and generously soak with your cleaner.- Work the solution through by gently squeezing, NOT wringing, to avoid damaging the foam structure.
- Repeat until all dirt is removed. You may need fresh solution for stubborn particles.
- Rinse & Dry: Rinse thoroughly with clean water, squeeze out excess, and set in a warm airy location (out of direct sun) to dry completely.
- Oil the filter: Once dry, saturate with foam filter oil and gently squeeze for even distribution. Do not wring – just squeeze out excess.
- Inspect the air box: Clean any accumulated dust or grime in the air box with a rag before re-installing the filter.
- Reinstall: Replace the filter on the cage, ensuring a perfect seal around the rim. Confirm that the retainer is secure, then reattach the seat and side cover.
- Final check: Run your hand all the way around the filter to feel for any gaps. A complete seal is essential to prevent engine damage.
When Should DRZ125L Owners Clean or Replace?
