Shop parts for a 2013 Yamaha TTR230 Dirt Bike.

This comprehensive guide from MotoSport.com will walk you through a full oil change and oil filter replacement on your 2013 Yamaha TTR230. We'll highlight the tools you need, every step of the process, and model-specific call-outs to ensure your dirt bike runs smoothly for many rides to come.

Tools and Supplies Needed

  • 1 quart (1.1 liters) of Yamalube 10W-40 (or high-quality 10W-40 motorcycle oil)
  • New oil filter (OEM or compatible, check your manual for the correct part number)
  • 19mm socket or wrench (for drain bolt)
  • 8mm socket (for oil filter cover)
  • Allen hex wrench (for specific cover bolts)
  • Oil drain pan
  • Funnel
  • Rags or shop towels
  • Torque wrench (recommended for reassembly)
  • Brake/contact cleaner (for cleanup)
  • New O-ring for drain bolt and oil filter cover (optional but recommended)
  • Nitrile gloves (optional, for cleanliness)

Preparation & Safety

  • Warm up the engine for a minute or two to thin the oil, but let the bike cool slightly before working to avoid burns.
  • Ensure the bike is upright and secure (use a stand if available).
  • Always work in a well-ventilated area, and dispose of used oil and filters responsibly.

Step 1: Drain the Old Oil

  • Locate the 19mm oil drain bolt under the engine, just below the shift lever on the left side of the bike.
  • Place your drain pan under the drain bolt.
  • Remove the drain bolt carefully and set aside the locking washer or O-ring (replace if worn).
  • Allow oil to drain completely. Inspect for metal shavings or debris in the old oil, which could indicate internal engine issues.

Step 2: Replace the Oil Filter

  • While the oil is draining, locate the oil filter cover on the crankcase.
  • Use the 8mm socket to remove the oil filter cover bolts. Some bolts may require an Allen hex wrench.
  • Carefully remove the cover; oil may still drip, so have a rag ready.
  • Remove the old oil filter. Note orientation for reinstallation.
  • Inspect the filter cavity for debris and wipe clean if necessary.
  • Install the new oil filter, matching the correct orientation as the original.
  • Replace the oil filter cover, and consider installing a new O-ring.
  • Tighten oil filter cover bolts to 7 Nm (Newton meters) as specified in the 2013 owner's manual. Use a torque wrench if possible for precision.

Step 3: Reinstall the Drain Bolt

  • Inspect and replace the drain bolt O-ring or gasket if it is worn or damaged.
  • Reinstall the oil drain bolt and tighten to 43 Nm using a torque wrench if available.

Step 4: Add New Oil

  • Place a funnel into the oil fill cap at the top of the engine.
  • Pour in 1 quart (1.1 liters) of 10W-40 motorcycle oil. If you have replaced the filter, you may need a little more – add oil gradually to avoid overfilling.
  • Replace the oil fill cap securely.

Step 5: Confirm Oil Pressure (2013 TTR230 Specific Call-out)

  • Yamaha recommends verifying oil pressure by loosening the bleed screw just behind the spark plug on the right side of the cylinder head.
  • Start the engine and let it idle.
  • Watch for oil seeping from the bleed screw to confirm pressure. If you see oil, tighten the screw to 5.2 ft-lb of torque. If you do not, stop engine immediately and consult a dealer.

Step 6: Check Oil Level

  • With the bike level, wait a few minutes after running the engine.
  • Use the dipstick or oil level window to check oil. If necessary, top off with small increments until the proper level is reached.

Step 7: Final Clean-Up and Inspection

  • Spray a little brake or contact cleaner around the work area to clean any residual oil.
  • Wipe down the engine and exhaust carefully (avoid burns if still hot).
  • Inspect thoroughly for leaks from the drain bolt, oil filter cover, and bleed screw.
  • Reinstall any skid plates or plastic removed at the beginning.
  • Organize and clean your tools.
  • Dispose of used oil and the old filter at an authorized recycling center or your local Yamaha dealer.

2013 Yamaha TTR230: Important Call-Outs

  • The TTR230 engine design has remained largely unchanged for years, meaning most oil change procedures are identical across model years (including 2013).
  • Always torque bolts to Yamaha's specs: oil filter cover bolts (7 Nm), drain bolt (43 Nm), bleed screw (5.2 ft-lb).
  • The oil bleed screw is unique—don't skip this verification step, as proper oil flow is crucial to engine longevity.
  • Use only motorcycle-specific oil (never automotive oil) to protect your wet clutch and engine internals.
  • If you notice milky oil or unusual debris, investigate further before riding.
  • Double-check for gasket or O-ring wear at every service interval.

Wrap-Up

  • Changing the oil yourself saves money, protects your engine, and helps you learn your bike.
  • Follow these steps exactly, keep your MotoSport.com supplies stocked, and ride with confidence on your finely-maintained 2013 Yamaha TTR230.
