2017 Yamaha TTR230 Model-Specific Call-Outs

  • The engine design and oil change procedure have remained consistent for years, simplifying maintenance.
  • The oil drain bolt is located just below and behind the gear shift lever on the left side of the bike.
  • This model has a removable screen (sometimes called a thimble strainer) in addition to the oil filter, which should be cleaned each oil change.
  • There is an oil system bleed screw on the right side of the cylinder head (behind the spark plug). This must be used after changing the oil to verify oil pressure has been restored.

Step-by-Step: Changing Oil in a TTR230

  1. Warm Up the Engine
    • Start your TTR230 and let it run for 3–5 minutes to warm the oil. Warm oil drains more easily, carrying away trapped particles.
    • Shut off the engine and allow it to cool enough to avoid burns.
  2. Place the Bike Securely
    • Stand your bike upright on a stable, level surface. Use a center stand or bike stand if possible.
  3. Drain the Old Oil
    • Locate the oil drain bolt (19mm) under the gear shift lever on the left side.
    • Place your oil pan beneath the drain bolt.
    • Remove the bolt carefully. Allow all oil to drain. You may need to slightly tilt the bike for better drainage.
    • Remove and inspect the drain bolt washer. Replace if worn or damaged.
    • Pull out and clean the thimble screen/strainer with brake cleaner and a rag—be sure to remove any debris.
  4. Change the Oil Filter
    • The oil filter is accessed by removing the cover on the right side using an 8mm socket and/or Allen wrench.
    • Pull out the old filter.
    • Inspect and clean the filter cover and gasket surfaces. Replace the gasket if necessary.
    • Install the new oil filter, facing the correct direction (consult the manual or check markings).
  5. Reinstall Drain Bolt and Filter Cover
    • Reinstall your cleaned and inspected drain bolt and screen, torquing to the manufacturer’s spec.
    • Refit and tighten the oil filter cover bolts evenly to avoid leaks. Use a torque wrench if available.
  6. Refill Fresh Oil
    • Remove the oil fill cap (right side of the engine).
    • Pour in fresh 10W40 oil. Start with about 1 quart.
  7. Initial Oil Level Check
    • With the bike upright, insert the dipstick without threading it in, and confirm the oil level is within the recommended range.
  8. Prime the Oil System (Critical Model Step)
    • On the 2017 TTR230 (and all TTR230 models), verify oil pressure after refilling:
    • Locate the oil bleed screw on the right side of the cylinder head (behind spark plug).
    • Loosen the bleed screw.
    • Start the engine and let it idle. Watch for oil seeping from the screw—this confirms oil pressure is restored.
    • If you do not see oil after a minute, shut off the engine and check installation—running without oil pressure can damage the engine.
    • Tighten the bleed screw to 5.2 ft-lbs torque after confirming oil flow.
  9. Run the Bike and Final Oil Check
    • Run the bike for several minutes at idle, then shut it off.
    • Allow oil to settle, then check the level again. Top off as needed.
  10. Inspect for Leaks & Clean Up
    • Thoroughly examine all drain/fill points and filter area for leaks.
    • Spray contact/brake cleaner on any oil spills or residue.
    • Dispose of your used oil properly at a recycling center or auto parts store.

Final Tips and Warnings for TTR230 Owners

  • Never overfill the oil. Too much oil can damage your engine just as quickly as too little.
  • Always use a torque wrench when tightening bolts to manufacturer recommendations—especially the oil drain and filter cover bolts.
  • Record your oil change in your maintenance log for warranty and future reference.
  • Clean tools and work area after completion.
