Regular oil changes are crucial for keeping your 2014 Yamaha TTR110 running smoothly and extending engine life. This guide covers all the tools you'll need, each step in the process, and highlights specific tips that apply to this model. Follow these directions to perform this essential maintenance confidently and correctly.

Tools and Supplies Needed

  • 10mm or 12mm socket/wrench (the drain bolt is typically 12mm, but double-check your bike)
  • Oil catch pan or container
  • Rags or shop towels
  • Funnel
  • Measuring cup (to measure exact oil volume)
  • Fresh 10W-40 motorcycle oil (Yamalube recommended), quantity: 28 fluid ounces (0.82L)
  • Disposable gloves (optional for cleaner hands)

Special Notes for the 2014 Yamaha TTR110

  • No oil filter to replace: The TTR110 does not have a replaceable oil filter. This makes oil changes especially quick and cost-effective.
  • Oil capacity is 28 ounces (0.82L): Do not overfill.
  • 2012–2024 TTR110s use the same procedure and parts, with virtually no major changes since 2012.
  • Always use the correct viscosity motorcycle oil: 10W-40 is the safe choice, either Yamalube or another quality brand.

Step-by-Step Instructions

  • Warm up the engine for 5–10 minutes
    • This helps the oil drain out smoothly and completely.
  • Turn off the engine and secure the bike on a level surface.
    • Use a bike stand if possible to keep the bike upright.
  • Locate the oil drain bolt.
    • The bolt is located on the bottom left side of the engine case (underneath).
  • Place the oil pan underneath the drain bolt.
  • Use a 12mm wrench or socket to carefully loosen and remove the drain bolt.
    • Be careful as hot oil may come out quickly. Wear gloves if the bike's engine is still hot.
    • Let all the old oil drain into the pan; this may take several minutes.
  • Inspect the drain bolt and washer.
    • Wipe off any dirt or metal shavings. Replace the crush washer if it looks damaged or deformed.
  • Reinstall the drain bolt.
    • Hand-tighten first, then snug up with the wrench. Avoid over-tightening to prevent stripping the threads.
  • Remove the oil fill cap/dipstick on the right side of the engine.
  • With a funnel, pour in 28 oz (0.82L) of new 10W-40 oil.
    • Pour slowly; do not rush the process.
  • Check the oil level using the dipstick:
    • Insert the clean dipstick (do not screw it in), then remove and check the level.
    • The level should be between the minimum and maximum marks.
    • Tip: It's better to be slightly underfilled at first, then top off as needed. Too much oil can cause engine issues or leaks.
  • Start the engine and let it idle for 1–2 minutes.
    • This circulates the new oil through the engine.
  • Turn off the engine and wait 2–3 minutes to let oil settle.
  • Recheck the oil level with the dipstick, topping up if needed.
  • Reinstall the oil fill cap/dipstick securely.

Final Steps and Disposal

  • Wipe down any spilled oil and clean your tools.
    • It's good practice to always clean and put away your tools after use.
  • Dispose of used oil responsibly.
    • Take the old oil to a motorcycle dealer or local recycling center for safe disposal; never pour it on the ground or in drains.

Model-Specific Call-Outs for the Yamaha TTR110

  • No oil filter to change: Change oil more frequently if you ride in harsh conditions or at high RPM.
  • Check drain bolt threads: The case metal is soft aluminum, so never over-tighten the drain bolt.
  • Air filter service: While changing your oil, check the air filter. A clean filter improves performance and engine longevity.
  • Check for leaks after oil change: Start the bike and check around the drain bolt and fill cap for oil leaks before riding.
  • Do not overfill: Overfilling can lead to excess pressure and leaks, or airbox contamination.
