Changing the oil in your 2009 Yamaha TTR110 is one of the simplest and most important maintenance tasks to keep your dirt bike running reliably. This guide, proprietary to MotoSport.com, covers the required tools, precise steps, and critical tips for a smooth oil change specific to the 2009 Yamaha TTR110.

Tools and Materials Needed

  • 12mm wrench or socket (for the drain plug)
  • Oil drain pan or container
  • Funnel
  • Fresh oil (Yamalube 10w40 or equivalent, approximately 28 fluid ounces)
  • Cleaning rag
  • Measuring cup (for oil)
  • Gloves (optional, but recommended for cleanliness)

Preparation

  • Warm up your engine for 5–10 minutes. Warm oil drains faster and more completely than cold oil, helping remove engine contaminants. Do not let the engine get too hot; you just want it warm to the touch.
  • Turn off the engine and place the bike on a level surface, using a stand if available.

Oil Change Procedure

  • Locate the drain plug on the shifter side (left side) of the engine, just beneath the foot peg area. You will see a 12mm bolt pointing straight down beneath the engine case.
  • Place the oil drain pan directly under the drain plug to catch used oil.
  • Remove the oil fill cap/dipstick on the top or side of the engine to allow oil to drain faster and more completely.
  • Use your 12mm wrench or socket to carefully loosen and remove the drain plug. Be cautious, as the oil will be warm.
  • Allow the oil to fully drain. This may take several minutes. Gently tilt the bike from side to side to ensure maximum drainage.
  • Inspect the drain plug for any metal shavings or debris, and wipe it clean with a rag before reinstalling. There is no traditional oil filter on this model, which simplifies maintenance but makes frequent oil changes important for engine longevity.
  • Reinstall and tighten the drain plug by hand, then snug it with your 12mm wrench. Be careful not to overtighten—it is easy to strip the aluminum threads on this model. If possible, use a torque wrench and tighten to manufacturer spec (typically ~14 lb-ft—refer to your manual for precise value).
  • Add new oil using a funnel. Pour in approximately 28 fluid ounces (or 0.85 liters) of Yamalube 10w40 or a high-quality motorcycle-specific 10w40 oil. Measuring and pouring slowly helps avoid overfilling.
  • Replace the oil fill cap/dipstick and start the engine. Let it idle for 1–2 minutes, then turn it off and wait a few minutes for oil to settle.
  • Check the oil level with the dipstick. Make sure the level falls between the minimum and maximum marks. If necessary, add oil a little at a time to reach the correct level. Avoid overfilling, as excess oil can cause leaks, blow-by, or engine running problems.
    Tip: If you overfill, you can slowly loosen the drain bolt to release small amounts of oil until the correct level is reached.
  • Dispose of used oil at an approved recycling center or your Yamaha dealer—never pour used oil on the ground or throw it in the trash.

Important Callouts for the 2009 Yamaha TTR110

  • No oil filter to replace: The TTR110 does not have a replaceable oil filter, so routine oil changes are even more critical to prevent engine wear due to contaminants.
  • Do not overtighten drain plug: The aluminum threads are prone to stripping if excess force is applied.
  • Use correct oil capacity: Overfilling can cause running issues and engine damage; underfilling can lead to overheating and poor lubrication.
  • Always check the oil level after letting the bike idle and then settle: Proper level ensures optimal engine performance and reliability.
  • Consistency across model years: The oil change process is nearly identical for all Yamaha TTR110 models from 2008 onward, as there have been no major design changes affecting this procedure.

Final Tips

  • Wipe down any spilled oil and clean your tools after the job.
  • Record the oil change date and hours on the bike to help maintain regular service intervals.
  • If you ride in harsh conditions or frequently, change the oil more often.
