How to Change the Oil in a Suzuki DR-Z400
Step 1. Remove the oil filler cap/dipstick from the top of the frame, which helps the frame to vent and the oil to drain easier.
Step 2. Position a drain pan under the engine, and remove the 17mm drain bolt and washer from the bottom of the crankcase. Let the oil drain out.
Step 3. Inspect the drain bolt’s washer and replace it if necessary. Next, reinstall the drain bolt and washer, then torque them to 22 foot-pounds.
Step 4. Position the drain pan under the frame, and remove the 12mm drain bolt and washer from the bottom of the lower part of the frame. Let the oil drain out.
Step 5. Inspect the frame drain bolt’s washer and replace it if necessary. Next, reinstall the drain bolt and washer, and torque them to 22 foot-pounds.
Step 6. Remove the three 8mm bolts holding the oil filter cap.
NOTE: Be careful not to lose the spring beneath the oil filter cap when removing it.
Step 7. Remove the oil filter and the O-ring attached to the filter’s inner end. Inspect the O-ring and replace it if necessary.
Step 8. Reinstall the O-ring into the oil filter housing, then install the new oil filter with the larger hole facing inward. Next, reinstall the spring and the oil filter cap with the small arrow pointing upward.
NOTE: Avoid overtightening the three cap bolts.
Step 9. Refill the engine with 2 quarts of 10W-40 motorcycle oil. Make sure the oil is designed for wet-clutch motorcycles.
Step 10. Reinstall the oil filler cap/dipstick, then start the engine and let it idle for a few minutes to pull the oil through the frame and into the crankcase.
Step 11. Shut off the engine and let it sit for a couple of minutes so the oil can settle.
Step 12. Remove the oil filler cap/dipstick and check the oil level. To check the level, hold the filler cap/dipstick against the threads but don’t screw it in. Top off the oil if necessary, then reinstall the oil filler cap/dipstick and you’re done.
As noted, the steps for changing the oil on a Suzuki DRZ400 are the same or similar for all Suzuki motorcycles. However, if you want to see an oil change done on a street bike instead of a dirt bike, watch the video below to see how to do an oil change on a Suzuki TU250X.
