Tools & Supplies Needed

• 10mm and 14mm socket or wrench (for drain plug and oil filter cover bolts)
• Torque wrench
• Clean funnel
• Oil drain pan
• OEM Kawasaki oil filter (52010-1053) or equivalent
• 2 quarts of 10W-40 motorcycle engine oil (Kawasaki-approved, semi- or full synthetic)
• Clean rags or shop towels
• Rubber gloves (optional, for less mess)
• Small flathead screwdriver (for gently prying oil filter cover if needed)

Step–by–Step Oil Change Instructions

• Prepare the Work Area
  • Ensure your KLX300SM is on a level surface and fully supported with a stand.
  • If possible, run the engine for 2–3 minutes to warm up the oil—this helps it drain better. Then shut off the engine and allow it to cool slightly. Never attempt maintenance on a hot engine.
• Drain the Oil
  • Locate the oil drain bolt on the bottom left side of the crankcase.
  • Place your oil drain pan underneath the drain plug to catch the used oil.
  • Using a 14mm wrench or socket, carefully remove the drain bolt. Allow the oil to drain fully. Expect about 1.2 quarts to come out.
  • Inspect the drain bolt’s crush washer for wear; replace if damaged.
• Change the Oil Filter
  • Locate the oil filter cover on the right side of the engine.
  • Remove the three 10mm bolts holding the cover.
  • To avoid spills, press the cover inwards as you loosen the last bolt, then remove gently to take out the old oil filter and filter spring. Note orientation for reassembly.
  • Clean the filter cover and mating surfaces with a rag and check the O-ring for cracks or wear; replace if necessary.
  • Install the new filter and ensure the spring is seated properly behind it.
  • Refit the cover and torque the bolts to manufacturer specs (consult owner’s manual; typically 8 Nm/71 in-lbs).
• Install the Drain Plug
  • After the oil is fully drained, wipe any residue from the drain area.
  • Reinstall the drain bolt (with good washer) and torque to spec (see manual; generally around 29 Nm/21 ft-lbs).
• Add Fresh Oil
  • Remove the black oil filler cap (right side, above clutch cover).
  • Using a clean funnel, pour in 1.2 quarts of new 10W-40 oil.
  • To avoid overfilling, watch the sight glass window while adding oil; the level should be centered between the lines when the bike is upright. A bit under is better than too much.
  • Reinstall and tighten the oil fill cap.
• Check Oil Level and Leaks
  • Start the engine and let it run for 2–3 minutes. Shut off and let oil settle for a minute.
  • With the bike upright (not on side stand), check the oil in the sight glass; add small amounts if needed.
  • Inspect around the drain plug and oil filter for leaks.
  • Dispose of the engine oil responsibly—auto parts stores or recycling centers typically accept used oil.

KLX300SM-Specific Owner Tips & Call-Outs

• Oil Capacity: Approximately 1.2 quarts (1.1 liters) with oil filter change. Do not overfill—the sight glass is your guide (level should be in the middle).
  Source: Owner experience and KLX service manual overview.
• Filter Orientation: There is a small spring behind the oil filter. Make sure it’s reinstalled correctly; it’s critical for maintaining oil pressure.
• Genuine Parts: Always use a genuine Kawasaki oil filter or known-quality equivalent for the best fit and filtration. KLX300SM uses filter part number 52010-1053.
• Drain Plug Gasket: Always inspect and, if needed, replace the crush washer/gasket on the drain plug to ensure a leak-free seal.
• Engine Oil Type: Use Kawasaki-recommended 10W-40 motorcycle oil. Synthetic or semi-synthetic works well—synthetic is recommended after the engine break-in period.
• Warm-Up: If your bike is new, your first oil change is due at 600 miles. Afterward, follow the maintenance interval in the service manual (usually every 3000–4000 miles for normal use).
