Step-by-Step Oil Change Instructions
-
Warm Up the Engine
Run the engine for about a minute to bring the oil up to temperature. This helps the oil drain out more completely and suspends any contaminants in the oil. Do not let the engine get too hot. -
Remove the Oil Fill Cap
With the engine turned off, remove the oil fill cap. This allows air to enter and helps the old oil drain freely. Pro tip:– Letting air in ensures a more complete drain.
KLX250-specific note:– The oil fill cap is on the right-hand side of the engine. -
Drain the Old Oil
Position your oil drain pan beneath the drain bolt, located on the bottom of the engine. Use your 14mm socket and wrench to remove the drain bolt carefully.
Allow all oil to drain; carefully tilt the bike from side to side while it’s on the stand to assist drainage.
Heads up:– The 2020 KLX250 has an oil capacity close to 1.5 quarts, so expect that volume when draining.
Always inspect the drain bolt washer for wear and replace if necessary to prevent leaks. -
Remove and Replace the Oil Filter
Locate the oil filter cover, secured by two 8mm bolts. Remove both bolts and carefully pull off the cover.
Take care as there is a spring inside the cover — do not lose it. Remove the old oil filter.
KLX250 Call-out:– The filter’s tension spring can sometimes fall out or shift. Putting a dab of engine grease on the spring seat can help hold it in place during reassembly. This is especially useful to prevent misalignment when reinstalling. -
Install the New Filter
Place the new oil filter into the housing—ensure correct orientation as marked in your owner’s manual. Reinstall the spring if it’s become dislodged. Place the filter cover back and torque the bolts to spec (refer to your service manual for specific torque values). -
Replace the Drain Bolt
Once drained, fit the drain bolt back on, tightening with your 14mm socket. Use a torque wrench to avoid over-tightening—over-torqued drain bolts are a common cause of stripped threads on these engines. -
Refill with Fresh Oil
Insert a funnel into the oil fill port. Add just under 1.5 quarts of 10W40 motorcycle oil. If you’re within your first 600–1000 miles, stick to non-synthetic oil to promote ideal break-in wear. -
Check for Leaks & Verify Oil Level
Start the engine and let it idle for 30 seconds. Turn it off and wait another minute. Check beneath the bike and around the filter cover for leaks. Check oil level via the sight glass or dipstick and top off as needed. Do not overfill. -
Clean Up
Wipe off any oil drips or spills. Properly dispose of old oil and filter at your local recycling center.
