Tools and Supplies Needed
- Socket wrench (ratchet)
- 8mm socket (for oil filter cover bolts)
- Drain pan
- Oil filter (such as K&N 136 or OEM equivalent)
- 10W-40 motorcycle oil, full synthetic or conventional (see your owner's manual for exact capacity, generally about 1.7–1.8 liters when changing oil and filter)

- Gloves and rags (for cleanup)
- Torque wrench (recommended for accuracy but not mandatory)
Step-by-Step Instructions
-
Warm Up the Engine
Start your DRZ250 and let it run for a few minutes to warm up the oil. Warm oil drains faster and more completely. -
Remove the Oil Filler Cap
Locate and unscrew the oil filler cap/dipstick on the crankcase. This helps vent the system so all the old oil can flow out easily. -
Place Your Oil Drain Pan
Position the drain pan directly under the engine's drain plug. -
Remove the Drain Plug
Carefully unscrew the drain plug and washer using your wrench. Let the oil drain completely.
Pro tip: Inspect the drain plug washer; replace if worn or damaged to avoid leaks. -
Replace and Tighten the Drain Plug
Once the oil stops dripping, reinstall the drain plug and washer.
If using a torque wrench, tighten to the manufacturer's recommended torque spec (typically 15 ft-lbs, but check your manual). -
Remove the Oil Filter Cover
The oil filter is accessible from the right hand side of the engine. Remove the three 8mm bolts securing the oil filter cover.
Carefully pull the cover away; take note of the spring behind the filter (don't lose it.) and observe the order of assembly. -
Remove the Old Oil Filter
Pull out the old oil filter, and allow any remaining oil to drain.
Clean the inside of the filter housing and the cover thoroughly.
Inspect the O-ring/gasket on the oil filter cover for damage—replace if needed to avoid leaks. -
Install the New Filter
Lightly oil the new filter's O-rings using fresh oil.
Install the spring (if it fell out), then insert the new filter in the same orientation as the old one.
Replace the cover and thread the 8mm bolts in evenly, tightening by hand first. Then, snug evenly; do not overtighten as this can damage the gasket and cover. -
Refill with Fresh Oil
Using a funnel, pour in the recommended amount of oil. For a full oil and filter change, this is generally 1.7–1.8 liters for the 2002 DRZ250, but double-check your owner's manual for confirmation. -
Check Oil Level
With the bike upright (not on the side stand), check the oil level using the dipstick or sight glass. Top off if necessary. -
Start and Inspect
Start the engine and let it idle for 2–3 minutes. Check for any oil leaks at the drain plug and filter cover.
Stop the engine and let it rest for a few minutes, then re-check the oil level. Add oil if needed. -
Dispose of Old Oil Properly
Take your used oil and filter to a designated recycling center.

Oil Filter Cap Tightening:
Do not overtighten the oil filter cover bolts—the gasket can deform, causing leaks or potentially damaging the cover itself.
“Make sure to not screw the cap on the oil filter on too tight or else you'll mess up the gasket.” - Watch for the Spring: When pulling off the filter cover, the internal spring can fall out; don't lose it, and reassemble in the original order for correct oil flow.
- Correct Oil Filter: Typical fitment is K&N 136 or OEM equivalent for this year and model.
- Use the Correct Oil Viscosity: SAE 10W-40 is recommended. Full synthetic is an excellent option for extended engine life and performance.
Tips for Success
- Always clean surfaces and parts before installing the new filter and before adding new oil.
- Have fresh shop rags on hand to quickly clean up any spills.
- Keep bolts organized to remember their original positions and torque.
