If you own a 2020 Yamaha TTR110, regular oil changes are critical for peak engine performance and longevity. This guide, proprietary to MotoSport.com, walks you through the tools needed, specific steps, and important call-outs for this make and model. Even if you're new to dirt bike maintenance, following these directions will ensure a professional-quality oil change every time.
Tools & Supplies Needed
- 12mm wrench or ratchet (for drain bolt)
- Oil catch pan or drip pan
- Funnel (clean, to avoid oil spills)
- Rag or shop towel
- Measuring cup (for accurate oil fill)
- Recommended oil: 10W-40 Yamalube or equivalent motorcycle-specific engine oil
- New crush washer for drain bolt (recommended, not always required)
- Dipstick (already on the bike, but you'll be using it to check your oil level)
- Gloves (optional but helps keep your hands clean)
Preparation
-
Run the engine for 5-10 minutes before changing the oil. This ensures the oil is warm, thin, and will drain out smoothly.
Tip: Warm oil carries away more contaminants. - Turn off the bike and secure it upright and level on a stand or the kickstand.
- As a best practice, protect your workspace with cardboard or a drip tray under the engine.
Step-by-Step Oil Change Instructions
-
Locate the oil drain bolt.
On the 2020 Yamaha TTR110, the drain bolt (12mm) is on the bottom of the engine case. -
Position your oil catch pan.
Place the catch pan directly beneath the drain bolt to catch draining oil. -
Remove the drain bolt.
Using the 12mm wrench, carefully remove the bolt. Allow all oil to drain out. This can take several minutes.
Caution: The oil may be hot. -
Inspect the old oil and the drain bolt.
Check for metal shavings or debris. Inspect the bolt and washer; replace the crush washer if damaged or worn. -
Reinstall the drain bolt.
Once the oil is fully drained, reinstall and hand-tighten the drain bolt. Then, snug it (do not overtighten) with the 12mm wrench. -
Add new oil.
- Remove the oil fill cap/dipstick.
- Using the funnel, pour in 28 fluid ounces (approximately 0.85 quarts or 828ml) of 10W-40 motorcycle oil.
- Pour slowly to avoid overfilling.
Call-out for TTR110: There is no oil filter to replace on this model, making the process straightforward.
Note: A measuring cup or clear oil jug helps you pour the precise amount, since overfilling can cause problems like leaks or engine blow-by. -
Check oil level.
- Stand the bike upright and insert the dipstick, but do not screw it in.
- Remove and inspect the oil level on the stick. It should be between the low and high marks.
- Top off as needed, being careful not to exceed the maximum mark.
Tip: After filling, start the bike and let it idle for 1-2 minutes. Shut it off and wait a few minutes, then recheck the oil level. This accounts for oil circulation and settling.
Caution: Overfilling may lead to engine damage or leaks; draining some oil is possible by loosening (not fully removing) the drain bolt and letting excess out if needed. -
Clean up.
Wipe any spilled oil with a rag. Dispose of the used oil properly – take it to a recycling center or a local auto parts supplier that accepts used oil.
Environmental tip: Never dump oil into drains or the environment. -
Final checks.
With the bike running, inspect the drain bolt area for leaks. Turn the bike off and recheck the oil level after a few minutes.
