Changing the Oil on a Kawasaki KLX 250

Step 1. Run the engine for a minute to circulate the oil, warm it up, and make it easier to drain.  

Step 2. Remove the oil fill cap to allow the engine to breathe. 

PRO TIP: Letting air into the engine makes it easier to drain the oil out of the bottom.

Step 3. Get a drain pan ready, and use a 14mm socket to remove the drain bolt. 

NOTE: Don’t lose the accompanying crush washer. If you lose it or find that it’s damaged, get a replacement drain plug crush washer.

PRO TIP: There’s a spring behind the oil filter that occasionally falls out. Use a dab of grease to stick it back into the center of the oil filter compartment and get it to stay in position.

NOTE: There’s a black grommet in the center of the filter that needs to face out toward you. The filter is directional, and will not work properly if installed backwards.

Step 9. Replace the fill cap, and run the engine for a couple of minutes to circulate the fresh oil. Then, check the level in the sight glass and top off the oil if necessary.
