Air Filter Cleaning – Replacement Guide for 2011 Suzuki DR650SE

Shop parts for a 2011 Suzuki DR650SE Dirt Bike.

The air filter is your 2011 Suzuki DR650SE’s first line of defense against dust, grit, and engine-damaging particles. Regular cleaning and timely replacement are essential for top engine performance and long-term reliability—neglecting this routine job can cause reduced power and increased fuel consumption. Unique to the DR650SE, the air filter sits behind the left side cover and airbox lid, combining easy access with a robust foam construction for effective filtration in tough dual-sport conditions.

How Often To Clean & Replace

  • Clean every 3,000 km (2,000 miles) or sooner after dusty rides.
  • Replace if you find any rips, cracks, or damaged foam during inspections or at the end of each riding season.
    Inspect more frequently when riding off-road, in dusty, or sandy conditions.

Tools & Supplies

  • JIS screwdriver (for airbox screws)
  • Nitrile gloves (recommended)
  • Non-flammable air filter cleaner or kerosene
  • Motorcycle-specific filter oil
  • Clean rags
  • Replacement filter (if needed)

Step-by-Step Air Filter Cleaning Process

  1. Remove the Side Cover & Airbox Lid:
    Using the JIS screwdriver, unscrew and carefully remove the left side cover and then the airbox cover.
  2. Extract the Air Filter:
    Locate and loosen the white plastic clip or retainer and remove the machine screw to free the filter cage and foam element.
  3. Inspect the Filter:
    Examine the foam closely. Cracks, rips, or deteriorated material means it’s time for a new filter. Reusable foam elements can be cleaned and re-oiled.
  4. Clean the Filter:
    Soak the foam filter in a bucket with air filter cleaner or kerosene. Gently squeeze (do not twist or wring—that can damage the foam) until dirt and oils are removed. Rinse with clean water and gently squeeze out excess.
    Let the filter air dry completely (overnight if possible).
  5. Oil the Filter:
    Apply a high-quality, motorcycle-specific foam filter oil. Work the oil through the foam until fully saturated but not dripping. If using aerosol oil, spray 8 cm from pleats, and let sit 20 minutes to ensure even coverage. Wipe off any excess.
  6. Reinstall the Filter:
    Fit the filter back onto the filter cage. If your DR650SE uses a secondary air filter or breather, check and clean or replace it following a similar process.
    Carefully align the assembly and secure it with the retainer and screw. Refit the airbox cover and side panel.

Special Considerations for the 2011 Suzuki DR650SE

  • The DR650SE’s air filter element is a dense polyurethane foam, making it rugged but still susceptible to cracking over time—thorough inspections during cleaning are key for engine safety.
  • Secondary Filters: A secondary breather filter may be fitted on the crankcase breather line. This filter should also be checked, cleaned, or replaced regularly to prevent dust from entering the engine oil.
  • Reassembly Tip: Ensure the plastic cage and white retainer are properly aligned to prevent filter deformation and air leaks. For easiest fit, insert the clip with its cup facing upward.
  • Order of Parts: Always reinstall components in reverse order, and ensure all covers are tightly secured to protect your newly cleaned filter.

Replacement Intervals & Best Practices

  • Regular cleaning prolongs foam life, but replace the element at least annually or with any sign of deterioration.
  • If you ride in wet or muddy terrain, inspect the filter more often—water or heavy mud can quickly clog or damage foam.
