Shop parts for a 1997 Suzuki DR650SE Dirt Bike.

Keeping the air filter of your 1997 Suzuki DR650SE clean and properly oiled is essential for reliable performance and engine longevity. The DR650SE uses a foam air filter element that requires regular cleaning and oiling, especially in dusty or off-road conditions. Owners of this model should also be aware of the secondary air filter and common installation quirks unique to the DR650SE design.

Recommended Maintenance Interval

  • Inspect and clean the air filter every 3,000 km (2,000 miles).
  • Replace the element sooner if used in extremely dusty or sandy environments.*

What You Need

  • Non-flammable cleaning solvent
  • Appropriate air filter oil (non-aerosol or spray type)
  • Clean rags
  • JIS screwdriver (for OEM screw heads)
  • Gloves

How to Remove the Air Filter

  1. Remove the left frame cover by releasing the retaining fasteners.
  2. Unscrew and remove the air cleaner case cover fasteners.
  3. Locate and remove the filter element support screw.
  4. Gently remove the foam filter element from its frame.*

Cleaning the Air Filter

  1. Fill a pan with non-flammable solvent.
  2. Completely immerse the foam filter and massage gently to loosen embedded dust and debris.*
  3. Lift and gently squeeze (do not twist or wring) to avoid damaging the foam structure.*
  4. Repeat until no visible dirt remains.
  5. Allow the filter to air dry completely – use a fan or set in the sun if possible.1

Oiling – Essential for Foam Filters

  1. Once fully dry, generously apply air filter oil. If using spray oil, hold nozzle about three inches from the foam and spray evenly on all surfaces. If using liquid oil, pour into a bag with the filter and work oil into all parts of the foam.2
  2. Squeeze out excess oil, leaving the filter slightly moist but not dripping.*
  3. Allow filter to sit for 20 minutes, then dab away any excess pooling oil.

Reinstalling the Air Filter

  1. Inspect the element and the airbox for any signs of damage or contamination. Wipe out dust from the airbox using a rag and cleaner safe for seals.1
  2. Reattach the filter to its frame, ensuring a proper seal with no gaps.
  3. Install the filter into the airbox, aligning it carefully for the DR650SE design. Use the white clip and original screw to secure it.4
  4. If you have trouble getting the clip to seat neatly, try flipping the cup side up before insertion, which helps avoid filter deformation unique to this bike.2
  5. Reinstall the air cleaner case cover and the left frame cover.

Notes & Model-Specific Tips for the 1997 DR650SE

  • The DR650SE features a secondary air filter (crankcase breather filter) behind the starter motor, which should also be inspected and cleaned or replaced periodically. To access it, gently separate its hose and use a zip-tie to fasten any new replacement in place as required.3
  • Always inspect the foam element for rips or tears – damaged filters allow dirt to enter your engine and should be replaced immediately.*
  • Do not use gasoline or harsh chemicals for cleaning; these can degrade the foam and cause it to fail.
  • The OEM filter is held in place with a JIS (Japanese Industrial Standard) screw head, not a Phillips. Using the correct JIS tool ensures you don’t strip the fastener.4

Regular maintenance of your 1997 Suzuki DR650SE’s air filtration system ensures consistent power, fuel efficiency, and protects your engine from premature wear. When in doubt, genuine and performance air filters are available at MotoSport–ensuring a perfect fit for your DR650SE.
