Step-by-Step Oil Change Guide
-
Warm Up the Engine
- Start your KLX250 and let it idle for about a minute, just enough to warm the oil. This helps the oil flow out more easily and removes suspended particles.
-
Prepare Your Work Area
- Park the bike on a level surface and, if available, use a stand for stability.
- Gather all tools and parts for easy access.
-
Remove the Oil Filler Cap
- Twist off the cap located on the right-hand side of the engine. This allows air in and ensures the old oil exits more quickly.
-
Drain the Old Oil
- Place your oil drain pan under the engine’s drain bolt (bottom of the engine case).
- Use a 14mm socket with ratchet to remove the drain bolt carefully. Oil will begin draining immediately — watch for hot oil.
- Allow the oil to fully drain. Gently tilt the bike back and forth to get as much old oil out as possible.
-
Replace the Oil Filter
- Using an 8mm socket, remove the two bolts holding the oil filter cover (right side of the engine).
- Carefully remove the cover — a spring sits inside; do not lose it.
- Pull out the old oil filter and dispose of it properly.
- If desired, use a dab of grease to keep the filter spring in place inside the cover for easier reassembly. Some users slightly widen the spring ends for a snug fit, which can make future changes easier.
- Insert the new oil filter, ensuring the orientation matches what you removed. Double-check the filter spring stays seated properly.
- Reinstall the oil filter cover, aligning it so the gasket seats flat, and hand-tighten the bolts. Finish tightening with the 8mm socket and torque wrench as specified in your manual.
-
Inspect and Reinstall the Drain Bolt
- Check the drain bolt’s crush washer for damage. Replace it if needed.
- Clean the bolt and threads, then reinstall and torque to manufacturer spec (refer to your service manual — common value is 21 Nm or 15 ft-lbs, but verify for your year).
-
Refill with Fresh Oil
- Insert a funnel into the oil fill port and pour in the recommended amount of 10W-40 motorcycle oil (approx. 1.5 to 1.7 quarts if also changing the filter, but check your owner’s manual for the exact volume)
- Replace the fill cap securely.
-
Check for Leaks and Final Fluid Level
- Start the engine and idle for 30-60 seconds.
- Shut off and let sit for a minute, then check the oil sight glass (or dipstick, if equipped). Top off if needed to bring oil to the recommended mark.
- Inspect the drain bolt and filter area for any oil leaks.
KLX250-Specific Call-Outs
- Oil Filter Spring: Take care not to lose the spring behind the oil filter cover; adding a bit of grease helps hold it in place for reassembly and future service.
- Proper Torque: Overtightening the drain bolt or filter cover can damage threads; always use a torque wrench.
- Full Oil Change Volume (2019 KLX250): Check the manual, but about 1.5 to 1.7 quarts is typical with a filter change.
- First Few Oil Changes: For new bikes, Kawasaki recommends using conventional oil for the first 600-1000 miles before switching to synthetic.
Pro Tips for a Cleaner, Easier Oil Change
- Let air in: Removing the filler cap at the top greatly speeds up the draining process.
- Level is key: Park the bike upright when checking oil level for the most accurate read.
- Dispose responsibly: Take used oil and filters to a proper recycling facility; never dump oil in the trash or outdoors.
