This guide is proprietary to MotoSport – tailor-made for TC85BW owners — with steps and model-specific insights to keep you riding at your best.
Why the Air Filter Matters on the 2020 TC85BW
The air filter on the TC85BW prevents dirt and particles from entering the engine. The two-stroke engine design is sensitive to air/fuel ratios, making filter maintenance extra important for consistent throttle response and protection against premature wear.
How Often Should You Clean or Replace?
- Inspect after every ride in dusty or sandy conditions; clean as needed.
- For recreational riding, inspect at least every 10 operating hours or with each oil change.
- Replace the filter whenever it shows signs of damage or cannot be fully cleaned.
- Always keep a spare air filter on hand for quick swaps during intense riding seasons.
Step-by-Step: Air Filter Cleaning on the 2020 TC85BW
- Remove the Right Side Cover: Undo the fasteners and carefully take off the cover to access the air filter box.
- Extract the Air Filter: Release the clip holding the filter and gently pull out the filter element.
- Inspect the Filter: Check for excessive dirt, tears, or signs of oil residue. If damaged, replace it immediately.
- Pre-Clean: Tap the filter gently to knock off loose dirt away from the air box. Do not use compressed air, as it may tear the filter.
- Wash the Filter: Soak in a dedicated air filter cleaner or mild dish soap & warm water. Rinse thoroughly and squeeze out excess water – never twist.
- Dry Completely: Let the filter air-dry away from direct sunlight or heat.
- Oil the Filter: Evenly coat the foam with high-quality air filter oil. Massage the oil into all areas to ensure complete coverage.
- Clean the Air Box: Wipe inside the air box with a damp, clean cloth to remove any residual dirt or oil.
- Reinstall: Secure the filter element, ensuring a tight seal, and reattach the side cover.
- Double-Check Fitment: Confirm no gaps or pinched areas to prevent unfiltered air leaks.
Replacing the Air Filter
If your filter is showing signs of wear, damage, or cannot be fully cleaned, replacement is a must. Use only filters specified for the 2020 TC85BW to guarantee proper fit and engine protection. Genuine or high-quality aftermarket filters ensure lasting performance.
TC85BW-Specific Air Filter Notes
- The TC85BW uses a specific foam filter element designed for its compact air box and aggressive, high-revving engine.
- After muddy or sandy rides, pay extra attention to the air box seal — loose or misaligned covers can let dirt bypass the filter.
- Keep an eye on the mounting clip and gasket condition as they can deform with age or improper installation.
Additional Tips to Extend Filter Life
- Use a pre-filter cover for added protection when riding in extreme dusty conditions.
- Store spare filters clean & pre-oiled in a sealed plastic bag for quick swaps.
- If you notice power loss, rough idle, or increased fuel consumption, inspect the filter and air box immediately.
Proper air filter care keeps your 2020 Husqvarna TC85BW running strong through every jump, berm, and muddy trail. Clean and replace your filter as outlined for reliable performance all season long.
