Changing the oil in your 1990 Suzuki DR650SE is a straightforward process that helps maintain the health and longevity of your engine.

This helps the oil drain more easily. 2. **Remove Skid Plate (If Applicable)**: If your DR650SE has a skid plate, you may need to remove it to access the oil drain plug. Use a wrench or socket to remove the bolts holding it in place. 3. **Position the Oil Drain Pan**: Place the oil drain pan under the engine to catch the old oil. 4. **Remove the Oil Drain Plug**:
  • Clean the area around the oil drain plug with contact cleaner and a rag.
  • Remove the plug using a socket or wrench (usually 32 mm). Be prepared for the oil to start draining out.
  • Replace the old crush washer with a new one.
5. **Replace the Oil Drain Plug**:

  • Clean the area around the oil filter cap with contact cleaner and a rag.
  • Remove the oil filter cap and then the old oil filter.

8. **Start and Check the Engine**:
