The 2018 Husqvarna 701Enduro combines high-performance engineering with modern reliability, making regular air filter maintenance crucial for optimal on- and off-road performance. This guide, unique to MotoSport, walks you through proper cleaning and replacement of your air filter, with details specific to the 701Enduro platform.
Why the Air Filter Matters on the 701Enduro
- Engine Protection: Keeps dirt, dust, and debris from entering your high-performance 693cc single-cylinder engine.
- Performance: Clean filters maximize airflow for better throttle response, horsepower, and fuel economy.
- Model Specifics: The 2018 701Enduro typically uses a high performance, washable cotton gauze air filter or an upgraded foam filter. Both can be cleaned and reused, unlike paper filters found in some other models.
Inspection Interval – When to Clean or Replace
- Routine Check: Inspect at every oil change or every 1,000 miles, whichever comes first.
- Regular Cleaning: Clean at least every 5,000 kilometers (about 3,100 miles), or more often in dusty or off-road environments. Performance decreases and engine wear will increase if neglected.
- Replacement: If the filter is damaged, torn, or cannot be fully cleaned, replace it with a quality cotton gauze or foam upgrade specific to your 701Enduro.
How to Access the Air Filter
- Make sure the bike is cool and on a stable stand.
- Remove the seat: Release it via the rear latch or key mechanism.
- Locate the airbox underneath.
- Unbolt or unclip the airbox cover – the filter is immediately accessible.
Cleaning Process for Washable Cotton or Foam Filter
- Remove the filter gently to prevent debris from entering the intake.
- Inspect for any tears, cracks, or excessive wear. If damaged, replace.
- For cotton gauze filters:
- Tap gently to remove loose debris.
- Apply a proprietary air filter cleaner and allow it to soak per cleaner instructions.
- Rinse with low pressure water from the clean side outward.
- Allow to air dry fully (never use compressed air or heat).
- Re-oil using a light application of approved filter oil, ensuring even coverage but avoiding oversaturation.
- For foam filters:
- Wash with mild soap and warm water or a foam filter-specific cleaner.
- Rinse thoroughly and squeeze (do not wring) until water runs clear.
- Let the filter dry completely.
- Apply foam filter oil evenly – work into the foam until the entire surface is slightly tacky.
Reinstalling the Filter
- Make sure the sealing edges are clean on both filter and airbox.
- Refit the filter carefully to ensure a proper seal on the airbox rim.
- Secure the airbox cover and seat.
Unique Notes for 2018 701Enduro Owners
- The 701Enduro's air filter location makes for quick removal, enabling rapid trailside cleaning or filter swap for riders pushing through extended off-road stages.
- Upgrading to a high-flow reusable filter provides not only better performance but also improved filtration – some filters can boost airflow by 50 percent and offer filtration efficiencies exceeding 98%.
- Always confirm your replacement filter's fitment to avoid leaks or intake misalignment, which can compromise engine health.
- Factory tuning is robust for dual-sport work, but a dirty filter will cause more noticeable throttle delays and decreased fuel economy on this high-output single.
Final Tips
- Carry a spare, freshly oiled filter on multi-day rides or races for easy mid-event swaps.
- Keep a filter cleaning kit in your garage; regular cleaning is faster than repeated replacements and saves money in the long run.
