Changing the oil in your 2010 Yamaha TTR110 is straightforward and essential for maintaining engine health and performance. This walkthrough offers everything you need to accomplish a professional-quality oil change specifically for your TTR110, with important call-outs for this make and model.

Tools & Supplies Needed

  • 10W-40 oil (Yamaha recommends Yamalube 10W-40; requires 28 ounces/0.85 quarts for service fill)
  • 12 mm socket or wrench
  • Oil drain pan
  • Funnel
  • Shop rags or paper towels
  • Gloves (optional)
  • Measuring cup for precise oil fill (recommended)
  • New crush washer for drain bolt (optional but best practice)

Preparation

  • Warm up the engine for 5–10 minutes. This thins the oil so it drains easier and more completely.
  • Turn off the engine and secure the bike on a level surface, preferably using a bike stand.

Step-by-Step Oil Change Instructions

  • Locate the drain plug: The oil drain bolt is on the left side of the engine case, beneath the bike. Place your drain pan under the plug.
  • Remove the drain bolt: Use your 12mm socket or wrench to carefully loosen and remove the bolt. Be cautious—the engine and oil may remain hot. Allow the oil to drain fully into your pan. Check the old washer; replace it with a new crush washer if worn.
  • Remove the oil filler cap: Unscrew the oil fill cap (on top of the case). This helps the oil to drain faster by allowing airflow into the engine.
  • Wait for complete drainage: Be patient and wait until oil is no longer dripping from the drain. Wipe any spilled oil from the crankcase area.
  • Reinstall the drain bolt: Thread the plug and washer by hand to avoid damage, then snug down with your 12mm wrench. Do not overtighten; the correct torque is approximately 14 ft-lbs (20 Nm) for the TTR110’s plug.
  • Add new oil: Using a funnel, pour in 28 ounces (0.85 quarts) of 10W-40 oil through the oil filler opening. Use a measuring cup for accuracy; this bike does not have an oil filter, so only fill to spec.
  • Check the oil level: Replace the oil fill cap, start the engine, and let it idle for 1–2 minutes. Turn it off and let it sit for a couple of minutes to allow oil to settle. Use the dipstick (attached to the filler cap) to check the level:
    • Wipe dipstick clean, reinsert into the fill hole without screwing in, remove and inspect level; oil should be between the upper and lower marks.
    • Add small amounts if needed, checking each time to avoid overfilling.
  • Dispose of used oil responsibly: Transfer old oil to a sealed container, then take it to a recycling center or local auto parts store that accepts used oil. Never dispose of oil in the trash, drains, or outdoors.
  • Clean up: Wipe any spilled oil and clean your tools before putting them away.

2010 Yamaha TTR110-Specific Call-Outs & Tips

  • No oil filter: The TTR110, including the 2010 model, does not have an external oil filter—oil changes are even simpler and require diligence in regularity.
  • Oil volume: Always use the precise amount (28 fl. oz/0.85 qt). More or less can harm the engine.
  • Check after running: Always check the oil level after running the bike for a couple of minutes and allowing it to sit, as the dipstick reading can be inaccurate if oil hasn’t settled yet.
  • Don’t overfill: Too much oil can cause blow-by, leaks, and engine damage. If you overfill, carefully loosen but don’t remove the drain bolt to let excess oil escape, or use a syringe to draw some oil from the fill hole.
  • Crush washer: Always inspect and, if necessary, replace the crush washer under the drain bolt to prevent leaks.
  • Disposal: Proper disposal of used oil is crucial for environmental safety; Yamaha dealers and auto parts stores typically offer recycling services.

Why Frequent Oil Changes Matter

  • Frequent oil changes remove abrasive contaminants and maintain optimal lubrication, essential for the TTR110’s small, hard-working engine.
  • Even if the bike isn’t used often, change the oil at least once a season or after long rides, races, or dusty conditions.

Conclusion

Performing an oil change on your 2010 Yamaha TTR110 is one of the easiest, most cost-effective ways to ensure your dirt bike stays reliable and fun to ride. With the right tools, a bit of patience, and careful attention to the oil type, volume, and disposal, you’ll be ready to keep your TTR110 in top shape for years of riding.
