Shop parts for a 2020 Yamaha TTR230 Dirt Bike.

Changing the oil on your 2020 Yamaha TTR230 is a straightforward but essential maintenance task that keeps your dirt bike running smoothly and ensures longevity. Below you'll find all the steps, tools, and special tips tailored for the TTR230. This guide is proprietary to MotoSport.com and designed for both new and experienced owners.

Tools and Supplies Needed

  • Yamalube 10W-40 (approx. 1 liter)
  • New oil filter (specific to Yamaha TTR230)
  • 19mm socket
  • 8mm socket
  • Allen hex wrench
  • Oil catch pan
  • Clean rags or shop towels
  • Brake/contact cleaner (for cleaning drain screen and area)
  • Torque wrench
  • Funnel
  • Disposable gloves (recommended)

Preparation

  • Warm up the engine for a couple of minutes. This decreases oil viscosity and helps drain contaminants more effectively.
    Tip: Avoid overheating. Just get the engine slightly warm to the touch.
  • Ensure the bike is upright and stable—ideally on a stand.

Step-by-Step Oil Change Procedure

  • Locate the Drain Plug:
    • Find the oil drain plug beneath the engine, just left of the shift lever.
    • It's a 19mm bolt with a flange—have your oil catch pan ready beneath it.
  • Remove the Drain Plug:
    • Use the 19mm socket to remove the plug.
    • Be careful—the oil may be hot.
    • Inside, you'll find a compression spring and an oil strainer. Make sure these don't drop into your pan or get lost; both need to be cleaned and reinstalled.
  • Drain the Oil Completely:
    • Let the old oil drain fully into the catch pan.
    • Allow a few minutes for all oil to evacuate, tilting the bike gently if needed.
      Tip: Running the engine briefly before service helps speed draining.
  • Clean and Inspect the Strainer:
    • Clean the strainer and spring with brake/contact cleaner to remove debris or sludge.
    • Inspect for excessive metal particles—shavings could indicate engine wear.
  • Remove and Replace the Oil Filter:
    • The oil filter cover is typically held on with 8mm bolts (consult your owner’s manual for torque specs).
    • Remove the cover, noting the position of the old filter and gaskets.
    • Install the new oil filter in the correct orientation; replace cover and tighten in a cross pattern.
    • Check the cover gasket and replace it if cracked or flattened.
  • Reinstall Strainer, Spring, and Drain Plug:
    • Re-seat the cleaned strainer and spring.
    • Install the 19mm drain bolt. Hand-tighten, then use a torque wrench to manufacturer’s spec (refer to your manual).
  • Add Fresh Oil:
    • Remove the oil fill cap and use a funnel to pour in about 1 liter of Yamalube 10W-40.
    • Replace the fill cap.
  • Prime the Oil System – Verify Pressure (Model-Specific Call-out):
    • The TTR230 has an oil bleed screw on the right side of the cylinder head behind the spark plug.
      • Loosen the bleed screw.
      • Start the bike and idle until oil seeps from the bleed hole—this confirms oil pressure is established.
      • If oil does not appear, stop engine, loosen screw more, and check again.
      • When oil appears, shut off the engine; torque the screw to spec (5.2 ft-lb).
      Important: If you never see oil bleed from this point, do NOT run the engine—contact a Yamaha dealer immediately.
  • Check for Leaks:
    • Run the engine briefly and inspect around the oil drain, filter cover, and bleed screw for leaks.
    • Shut off the bike, allow it to rest, and recheck the oil level with the dipstick or sight glass. Top off if needed.
  • Dispose of Oil Responsibly:
    • Take used oil to a certified recycling center, Yamaha dealer, or participating auto parts stores.
  • Clean Work Area and Tools:
    • Wipe up any drips/spills, wash hands, and store your tools for next time.

Model-Specific Tips & Reminders for the 2020 Yamaha TTR230

  • The engine, filter, and oil circuit designs have remained consistent for years, so these steps broadly apply to all TTR230s, including the 2020 model.
  • Check the oil bleed screw every time you change the oil; you must verify pressure before riding again.
    This is unique and critical—skipping this step can result in catastrophic engine failure.
  • The oil filter is a small "thimble" or "top hat" type—be sure you have the right replacement, and clean the filter cavity before installing the new filter.
  • Always double-check the orientation of all gaskets and filters to avoid leaks or damage.
  • The total oil volume (including filter change) is about 1 liter, but always rely on the dipstick/sight glass for final fill confirmation.

Conclusion

With these steps, your 2020 Yamaha TTR230 is ready for more rides with fresh oil protecting its engine. Remember: never skip the oil bleed screw check, always use manufacturer-recommended fluids and filters, and dispose of waste oil responsibly. Keeping up with regular oil changes is one of the best investments you can make in the reliability and life of your dirt bike.
