Tools and Supplies Needed
- 14mm socket and ratchet (for removing the oil drain plug)
- 8mm socket and ratchet (for the oil filter cover)
- Replacement oil filter (HighFlo HF112 or OEM, always check your manual for confirmation)
- Two quarts 10W-40 four-stroke engine oil (JASO MA certified for wet clutch)

Model-Specific Call-outs for the 2001 KLX300
- Oil capacity:– Approximately 1.2 liters (about 1.27 US quarts) with filter replacement. Always double-check your owner’s manual for your model year.
- Drain plug location:– Left side of the skid plate, easily accessible with the bike upright or on a stand.
- Be careful not to overtighten the oil drain plug–stripped threads in the engine case are costly repairs.
- Watch for two small indents in the oil sight window–these indicate the proper oil level fill line for your KLX300.
- Cleanliness is key: the KLX300’s oil system is sensitive to debris; never let dirt into the open crankcase.
Step-by-Step Oil Change Procedure
-
Warm up the Engine
Start and run the engine for about 5 minutes. This helps thin the oil so it drains out more effectively. -
Place the Bike Upright
Use a bike stand to keep the bike as upright as possible. This ensures the oil drains fully from the crankcase. -
Remove the Drain Plug
Find the oil drain plug under the left side of the engine (toward the back of the skid plate). Use your 14mm socket and ratchet to remove it. Let the oil flow into your catch pan.
- Careful: The oil might be hot. Gloves and caution are recommended.
-
Remove the Oil Filter Cover
Using your 8mm socket, remove the three bolts holding the oil filter cover on the engine’s right side. Gently remove the cover and pull out the old oil filter.
- Tip:– Note the orientation of the filter and any rubber seals or springs—reinstall in the same order.
- Wipe out the filter area with a clean rag if necessary, being careful not to introduce lint or debris.
-
Prepare and Install the New Oil Filter
Lightly oil the rubber gasket on the new filter with fresh engine oil. This helps seal once reinstalled. Replace the filter, lining up any holes on the end so oil flows properly through the filter and into the engine. Replace any springs or washers if required. -
Reinstall the Oil Filter Cover and Drain Plug
Carefully reinstall the filter cover with its bolts. Snug them down evenly (do not overtighten). Replace the drain plug and tighten it–do not overtighten; use a torque wrench if possible (check your manual for the correct torque specification). -
Add Fresh Oil
Remove the oil fill cap (usually a black cap on the right side engine cover). Using your funnel, add 1.2 liters (about 1.27 quarts) of recommended 10W-40 motorcycle oil. Pause periodically to check the level.- Look at the sight glass: the oil should be between the two dots/lines while the bike is upright. Add oil as needed to reach this level, but do not overfill.
-
Check for Leaks and Final Steps
Restart the engine and let it idle for a minute. Turn off, wait a few minutes for the oil to settle, then double-check the oil sight glass, adding a small amount if necessary.
- Inspect the filter cover and drain plug areas for any drips or leaks before your next ride.
- Properly dispose of used oil and filter at a recycling center.
Troubleshooting and Tips Specific to the KLX300
- If you notice metallic particles in your old oil, this could indicate engine wear–monitor at each oil change and consult a professional if it gets worse.
- For first-time changes or after break-in, you might see more debris or discoloration; this is common for new or rebuilt engines.
- The oil filter must be installed with the open side facing in and lined up properly–if installed backwards, you will starve your engine of oil and cause severe damage.
- Always use oil designed for wet clutches; automotive oils with friction modifiers will cause clutch slippage.
With the right tools and a methodical approach, changing the oil on your 2001 Kawasaki KLX300 is straightforward and gives you peace of mind knowing you’re taking care of your machine.
