Air Filter Cleaning & Replacement Guide for 2019 Husqvarna 701 Enduro

Shop parts for a 2019 Husqvarna 701 Enduro Dirt Bike.

The 2019 Husqvarna 701 Enduro uses a paper air filter element as standard equipment, designed for reliable protection and performance in a broad range of riding conditions. Keeping this filter clean and ensuring timely replacement are critical to preserving engine performance and longevity – especially since the 701 Enduro's capable single-cylinder engine is sensitive to airflow and particulate control.

Why Air Filter Maintenance Matters on Your 701 Enduro

  • Enhanced engine performance: A clean air filter ensures optimum air supply, improving combustion and throttle response.
  • Engine protection: Traps dust and debris before they reach the engine internals, which is crucial for the 690 cc thumper design used in the 701 Enduro.
  • Fuel efficiency: Prevents the engine from running rich and consuming excess fuel.

How to Access the Air Filter

  1. Ensure the bike is cool and parked on a stable stand.
  2. Remove the seat by releasing the seat latch (located under the tail section).
  3. You will see the air filter box assembly directly underneath the seat.

Air Filter Removal

  1. Identify the top air filter cover and secure fasteners (usually HH collar screws M6x12 TX30).
  2. Carefully remove the screws and gently lift the air filter box cover.
  3. Extract the filter element from its housing, being cautious not to allow dust or debris to fall into the intake.

Cleaning the OEM Paper Air Filter (If Reusable)

  • If your 701 Enduro is equipped with the standard paper filter, do not wash with water or solvent. Instead, lightly tap it to dislodge loose dust or use low-pressure compressed air, blowing from the clean side out.
  • If the paper filter appears oil-soaked, heavily stained, or damaged, replace it immediately.

Upgrading to Foam or Cotton Reusable Filters

  • Aftermarket options such as foam or oiled-cotton air filters are available for the 701 Enduro and provide improved filtration and the option to clean & reuse.
  • Reusable foam or cotton filters should be cleaned every 5,000 kilometers (or sooner in dusty conditions). Use filter-specific cleaning solution and re-oil per the manufacturer's instructions for optimal protection and airflow.

Reinstallation & Replacement

  1. Ensure the filter box and surrounding area are spotless before installing the filter to prevent debris from entering the intake.
  2. Install your cleaned or new air filter element, making sure it is correctly seated and sealed around the edges to prevent bypass.
  3. Reattach the filter box cover and torque fasteners securely, but do not overtighten.
  4. Replace the seat and ensure it is properly latched before use.

Special Notes for 2019 701 Enduro Owners

  • The 701 Enduro's intake and air box design is optimized for efficient airflow but may also allow more debris than smaller-displacement models – especially in dusty off-road use. Inspect the filter more frequently if you often ride in dirty or sandy environments.
  • If installing a high-flow aftermarket filter, monitor fuel mixture and consider fuel management adjustments, as additional airflow may cause a lean running condition on certain bikes.

Regular air filter servicing is one of the most effective ways to protect your Husqvarna 701 Enduro's engine and keep it performing at its best – on or off the road.
