Why Clean & Replace Your Air Filter?

  • Protect your engine from dust, dirt & debris
  • Maintain optimal combustion & efficiency
  • Extend air filter & engine life with regular service

Preparation – What You Need

  • Disposable gloves (to keep hands clean & protect filter from oils)
  • Torx screwdriver or JIS #2 screwdriver (for the air box cover screw)
  • Two buckets
  • Motorcycle-specific air filter cleaner (kerosene or proper cleaner recommended)
  • Motorcycle air filter oil (aerosol or liquid)
  • Clean water
  • Replacement foam air filter (if needed)

How to Remove the Air Filter

  1. Remove the left-hand side cover from your DR650SE.
  2. Unbolt the airbox cover using a Phillips or JIS screwdriver.
  3. Remove the white retainer clip and machine screw holding the filter in place.
    Note: If the screw is original, it may be tight; use gentle steady force.
  4. Pull the filter cage and foam element out carefully.

Inspecting the Air Filter

  • Check the foam for cracks, tears, or excessive brittleness.
    If damaged, replace immediately to avoid engine contamination.
  • Minor stains are normal if the filter is structurally sound.

Cleaning Process (for Foam Filter)

  1. Fill one bucket with ~600ml of air filter cleaner.
  2. Submerge & massage the foam filter gently until dirt & oil release.
  3. Never soak for extended periods&mdashfoam can break down.
  4. If heavily soiled, repeat with fresh cleaner.
  5. Rinse thoroughly in clean water until residue is gone.
  6. Completely air-dry the filter&mdashideally overnight.
  7. Inspect again for wear now that it’s clean.

Oiling the Air Filter

  1. Apply air filter oil: if using aerosol, hold it about 3 inches from pleats and spray for even coverage.
    For liquid oil, pour into a bag, add filter, and massage until fully coated&mdashno dry spots.
  2. Let the filter settle for 20 minutes, then check for missed areas.
  3. Squeeze out excess oil&mdashbut do not wring&mdashas this could damage foam.

Installation Tips for the DR650SE

  • Ensure the filter sits flush and fully sealed in the housing.
  • Install the retainer clip with the cup facing up&mdashthis prevents filter damage and makes installation easier.
    Push gently and check that the filter is not deformed by the clip.
  • Reinstall the machine screw and side panel securely.

Replacement Intervals

  • Inspect after every major ride, especially in dusty conditions.
  • Clean every 10-20 hours of off-road use, or monthly.
  • Replace if the foam is brittle, torn, or fails to seal properly.

MotoSport Notes for 1993 DR650SE Owners

  • This model features a secondary air filter hose out of the crankcase&mdashcheck & clean this regularly as well.
  • The air filter retainer is a unique cup-style clip; improper installation may deform the filter and cause gaps.
  • Consider zip-tying the secondary filter for better fitment as shown in tech tips from experienced owners.
  • Factory foam filters may have long service life, but age can cause breakdown&mdashcheck the build date if possible.

Keep your 1993 Suzuki DR650SE breathing clean&mdashreliable air filter care means better power, longer engine life, and worry-free rides every season.
