Changing the oil on a 2022 Yamaha YZ65 is a straightforward maintenance task that helps keep your bike’s performance at its peak. This guide is proprietary to MotoSport.com and offers every detail you need—tools, fluids, procedures, and model-specific tips—to change the oil confidently in your 2022 YZ65.

Tools and Supplies Needed

  • 10mm box-end or ratchet wrench (for the drain bolt)
  • Drain pan (to catch the old oil)
  • Measuring cup or oil jug (to measure new oil)
  • Funnel (for easy refill)
  • Paper towels or shop rags (for cleanup)
  • Replacement oil (10W-30 engine oil or 85W gear oil, per your preference and Yamaha’s spec)
  • New copper crush washer for the drain bolt (recommended but optional, reuse if undamaged)

Recommended Oil

  • Use a quality 10W-30 motor oil or an 85W gear oil.
  • Yamaha recommends their own Yamalube, but any reputable brand—such as Castrol Power 1 10W-30 or similar—works well.

How Much Oil Does the 2022 YZ65 Take?

  • Oil Capacity: 500 mL (0.5 liters) is required for a complete oil change on the 2022 YZ65.

Step-By-Step Procedure

  1. Warm Up the Engine
    • Start the bike and let it idle for a few minutes. This thins the oil, helping it drain completely.
    • Shut the engine off and place the bike upright on a stand or level surface.
  2. Remove the Oil Fill Plug
    • Locate the oil fill plug at the top of the clutch cover (right side of the bike).
    • Remove the fill plug and set it aside on a clean paper towel.
  3. Drain the Old Oil
    • Position the drain pan directly under the drain bolt. The bolt is on the right side, just behind the rear brake pedal.
    • Use a 10mm wrench to loosen and remove the drain bolt. Be mindful–the rear brake lever may make access a little awkward, but the bolt can be removed with some finesse.
    • Ensure that the copper crush washer comes out with the drain bolt. Do not lose it.
    • Let the old oil drain completely. It’s best to leave it for several minutes for a thorough drain.
  4. Inspect and Clean
    • Examine the drain bolt and washer for wear. Replace the washer if deformed or damaged.
    • Wipe the drain bolt clean before reinstalling.
  5. Reinstall the Drain Bolt
    • Fit the copper washer back onto the bolt, then thread the drain bolt back into place by hand.
    • Tighten the bolt to 10 Nm (Newton meters) of torque using a torque wrench if available. Do not overtighten.
  6. Add New Oil
    • Insert a funnel into the oil fill port at the top of the right crankcase cover.
    • Pour in 500 mL (0.5 Liters) of fresh oil. Do not overfill.
  7. Replace the Fill Plug
    • Install the oil fill plug and snug it by hand. Check the O-ring for wear and replace if needed.
  8. Check for Leaks
    • Wipe away spilled oil and inspect the drain bolt and fill plug areas for any leaks.
  9. Start the Engine and Check Oil Level
    • Start the bike, let it idle for a minute, then turn it off.
    • Let oil settle back down for a minute. Check for leaks again. Reconfirm the oil level through the inspection window or per manufacturer instructions, and add a little more if necessary (but do not exceed 0.5L).

Key Call-outs for the 2022 Yamaha YZ65

  • The drain bolt is difficult to access because of the rear brake lever. You may need to wiggle your wrench behind it. Take your time to avoid stripping the bolt.
  • Always use the copper crush washer. If it’s missing or damaged, replace it to prevent leaks.
  • Oil changes are recommended every five hours of operation or five races—whichever comes first.
  • No side oil check bolt: Unlike many two-strokes, the YZ65 does not have a check-level bolt. Rely on the manufacturer’s fill quantity (500 mL).
  • Use oils formulated for wet clutches to prevent clutch slipping.

Additional Tips

  • Dispose of old oil responsibly at a local recycling center.
  • Record your oil change interval in a maintenance log to maintain the bike’s service history.

Finishing Up

  • With the oil changed and everything buttoned up, take the bike for a short ride and recheck for leaks.
  • This routine keeps your 2022 Yamaha YZ65 in optimal riding condition and maximizes its long-term reliability and performance.
