Maintaining a clean air filter is critical for the performance and longevity of your 2020 Husqvarna TC85. A dirty or clogged air filter can rob your 85cc two-stroke of power, reduce throttle response, and shorten engine life. This guide by MotoSport.com provides proprietary step-by-step instructions specific to the 2020 TC85 so you can keep your bike running at its best every ride.
Understanding Your 2020 TC85 Air Filter
The stock 2020 Husqvarna TC85 uses a dual-layer foam air filter designed to provide maximum protection and airflow in the toughest track and trail conditions. Aftermarket upgrades like Twin Air also fit this model, but factory dimensions and fitment are key for both OEM and performance options.
When to Clean or Replace Your Air Filter
- Clean the filter after every ride in dusty or sandy conditions.
- For typical trail or motocross use, inspect after every ride and clean when visibly soiled.
- Replace the filter immediately if you find any tears, thinning foam, or shrunken areas.
- Always clean and re-oil the filter before the first use of a new one.
Proprietary MotoSport Step-by-Step Cleaning Instructions
- Remove the seat – Use your bike's seat release to access the airbox.
- Remove the air filter assembly – Unclip the retaining device, then carefully pull the filter and its backfire screen or cage out of the airbox.
- Check the airbox – Wipe out any dirt or debris from the airbox with a clean, damp cloth. Be careful not to let dirt fall into the intake.
- Remove the filter from the cage – Gently slide the foam filter off the support cage.
- Clean the filter – Submerge the foam filter in a bucket of air filter-specific cleaner or a high-quality degreaser. Massage gently to remove all oil and dirt. Rinse with warm water until the water runs clear.
- Dry completely – Let the filter air dry completely out of direct sunlight and away from heat sources to preserve the foam's structure.
- Re-oil thoroughly – Evenly apply air filter oil, working it by hand so the entire foam element is saturated but not dripping.
- Reassemble and inspect – Place the clean, oiled filter on the support cage. Double-check for tears or gaps. Make sure the filter fits snugly against the airbox sealing surface to prevent unfiltered air from entering.
- Install the filter assembly – Refit the filter into the airbox, secure the retaining clip, and reattach the seat.
Replacement Air Filter Recommendations
- Use OEM or exact-fit filters sized for your 2020 Husqvarna TC85 for best results.
- Aftermarket performance options (like Twin Air) are available and designed specifically for your model's airbox and cage.
- Do not use universal filters, which may compromise the seal or airflow.
Special 2020 TC85 Owner Notes
- The 2020 TC85 features tight airbox tolerances. Pay special attention to proper seating and cage orientation during reinstallation to avoid gaps or leaks.
- Inspect the intake boot during every filter service, as this generation's airboot is prone to developing cracks from repeated removals in racing conditions.
- Replace the air filter cage or support if it is cracked, bent, or deformed to maintain an optimal seal.
