Shop parts for a 2017 Husqvarna TC85BW Dirt Bike.
The 2017 Husqvarna TC85BW is engineered for youth riders seeking pro-level performance on the track, and regular air filter maintenance is essential to keep the engine breathing clean & performing at its peak. The TC85BW stands out with its high-strung two-stroke engine and limited air box space, making filter cleanliness and proper sealing especially critical for rider safety and engine life.
When to Service the Air Filter
- After every ride or race is ideal, especially in dusty or sandy conditions.
- At a minimum, inspect the filter every 20 operating hours.
Required Tools & Supplies
- MotoSport air filter cleaner or mild solvent
- Fresh air filter oil (foam filter-specific)
- Gloves and clean rags
- Replacement filter (optional for swap)
Removal: Accessing the TC85BW Air Filter
- Lift the seat latch at the rear, then carefully pull the seat up and back to remove it.
- Take off the air filter box cover by releasing its retainers – note the precise fit to prevent dirt intrusion.
- Unscrew the filter retaining knob and gently pull out the filter and cage assembly, taking care not to shake debris into the intake tract.
Cleaning the Air Filter
- Dry Cleaning: Carefully remove loose dirt and debris by tapping the filter. Never use compressed air, which can damage the delicate foam.
- Washing: Soak the filter in a recommended cleaner or gentle solvent, squeezing (not wringing) until residue is removed.
- Rinse with warm water and let the filter dry completely away from direct sunlight or high heat to avoid foam degradation.
Inspection – Special Note for 2017 TC85BW
- Check the filter and air box seal closely. The 2017 TC85BW filter cage must seal 360 degrees – look for tears, hardened foam, or warping which can let dirt pass directly to the engine.
- Examine the air box for trapped dirt or water. Clean thoroughly before reinstalling the filter.
Oiling & Reinstallation
- Apply fresh filter oil evenly and work it into the foam, ensuring complete but not excessive coverage.
- Install the filter back onto the cage, verifying perfect fit on all edges. Over-oiling can restrict airflow; under-oiling lets dust pass through.
- Install the assembly, making sure it seats flush without wrinkles or gaps.
- Replace the air box cover and seat, securely fastening them.
Replacement Guidelines
- Replace the filter at the first sign of crumbling, hardening, or holes. The more often you clean it, the sooner it will eventually wear out.
- Always have a spare, clean, pre-oiled filter ready for quick swaps on race day.
Tips Unique to the 2017 TC85BW
- The TC85BW's compact air box means even small sealing problems quickly become big issues. Double check filter positioning after every service.
- Its high-revving two-stroke engine is especially sensitive to dust ingestion—even a small breach can cause rapid engine wear or failure.
