MotoSport.com is proud to present this proprietary how-to designed for the dedicated dirt bike community.

Tools and Supplies Needed

  • 17mm socket and ratchet
  • 8mm socket and ratchet
  • Drain pan (for catching old oil)
  • Funnel (to prevent spills)
  • Rags or paper towels (cleanup)
  • Contact cleaner (optional, for cleaning the area)
  • New oil filter
  • New oil drain plug washer
  • Suzuki Service oil change kit (includes oil filter and O-rings—recommended)
  • SAE 10W-40 engine oil (API classification SE, SF or SG)—2.3 liters (2,300 ml)
  • Torque wrench (for precise tightening)

Preparation

  • Warm Up Engine– Start the bike and let it idle for 3–5 minutes. Warm oil drains faster and brings more contaminants with it.
  • Stabilize the Bike– Use a center stand, a jack, or a wooden block to keep the motorcycle upright and stable.

Step-by-Step Instructions

  • Remove the Skid Plate (If Equipped)
    Not all DR650SEs came with a skid plate from the factory, but many do. If you have one that impedes access to the drain plug, use your socket set to remove it.
  • Locate and Remove the Drain Plug
    Place your drain pan directly beneath the engine. Using the 17mm socket and ratchet, loosen and remove the drain plug.
    Tip: Remove the oil filler cap to allow the oil to drain faster.
    Specific Call-Out: Be mindful that the 1994 DR650SE drain plug should be tightened to 24 N-m (17.5 lb-ft) on reassembly. Always replace the crush washer under the bolt to prevent leaks, and inspect the plug for metal shavings which can indicate internal wear.
  • Drain the Oil
    Allow all the old oil to fully drain into your pan. This may take several minutes. Wipe up any spills and ensure the area is clean before reassembly.
  • Remove the Oil Filter
    Using your 8mm socket and ratchet, remove the three bolts holding the oil filter cover in place (left side of the engine). Remove the cover and take out the old filter. Inspect for excessive debris or metal fragments.
    Important: Remove and replace the O-rings on the filter cap and inside the housing. Lightly lubricate the new O-ring with fresh oil before installation.
  • Install the New Filter
    Insert the new filter, making sure the spring is in the correct position behind the filter. Reinstall the cover and tighten the bolts to 7 ft-lbs using a torque wrench. Do not overtighten, as this could damage the cover or O-ring.
  • Reinstall the Drain Plug
    Replace the crush washer and hand-thread the drain plug back in. Tighten to 24 N-m with a torque wrench.
  • Add Fresh Oil
    Insert a funnel into the oil fill port. Pour in 2.3 liters (2,300 ml) of SAE 10W-40 oil. Replace the fill cap.
  • Start and Run Engine
    Start the engine and let it idle for 3 minutes, allowing oil to circulate through the system and into the new filter. Turn off the engine and let it settle for 1 minute.
  • Check Oil Level
    Hold the bike upright and inspect oil level through the sight window (located on the right side of the crankcase). The oil should be between the upper and lower marks. Add oil in small increments as needed.
    Tip: Never overfill. Overfilling can cause engine and seal damage.
  • Clean Up and Dispose Properly
    Wipe up any spills and reinstall your skid plate if removed. Dispose of old oil and the used filter at a designated recycling facility. Never pour old oil into drains or onto the ground.

Specific Notes for the 1994 Suzuki DR650SE

  • Oil Capacity: Approximately 2.3 liters with filter change. Overfilling is a common mistake—use caution and check levels after running the engine.
  • Oil Type: Use SAE 10W-40 oil with SE, SF, or SG rating. Semi-synthetic or fully synthetic are both acceptable.
  • Oil Filter: Suzuki recommends changing the filter at each oil change—kits with new O-rings are affordable and strongly recommended for leak prevention.
  • Torque Specs: Drain plug–24 N-m; Filter cover bolts–7 ft-lbs.
  • Disposal: Be environmentally responsible with used oil and filters.
