Step-by-Step Guide to Changing Oil in a 2018 Yamaha TTR110
-
Warm Up the Engine
- Start the bike and let it idle for 5-10 minutes. This warms up the oil, making it flow out faster and carry more contaminants with it.
-
Position the Bike and Oil Catch Pan
- Turn the engine off and place your TTR110 on a stable, level surface using a bike stand or kickstand.
- Slide the oil drain pan under the engine's oil drain bolt, which is located on the bottom left side of the engine.
-
Remove the Drain Bolt
- Use your 12mm socket and ratchet to loosen and remove the drain bolt. Be careful, as the oil may be hot.
- Allow all the oil to drain completely – this can take several minutes. Wipe off any drips from the bolt and case.
-
Inspect and Re-install the Drain Bolt
- Inspect the drain bolt's washer for damage; replace it if deformed or worn. A good seal prevents leaks.
- Reinstall the drain bolt by hand, then tighten snugly with your ratchet. Do not over-tighten, which can strip the threads.
-
Add New Oil (10W40, 28oz/0.85L)
- Remove the oil fill cap/dipstick from the engine's right side.
- Using a funnel, pour in 28 fluid ounces (just under a quart or 0.85 liters) of 10W40 motorcycle oil. Yamalube is preferred, but any motorcycle-specific oil suffices.
- Pour slowly to avoid spills, using the measuring cup or the marked quart container to verify the oil amount.
-
Check Oil Level
- Wipe the dipstick clean.
- With the bike upright and level, insert (do not screw in) the dipstick, remove, and check the oil level. Repeat until the oil is within the correct marks.
- If you overfill, loosen the drain bolt slightly to let out excess oil, then check again.
- If needed, top off the oil by adding small amounts with the funnel and re-checking with the dipstick.
-
Run the Engine and Recheck
- Start the engine and let it idle for 2 minutes; then shut off and let stand for another 3-5 minutes.
- Recheck the oil level with the dipstick as before, topping off as necessary.
-
Final Inspection
- Check for leaks around the drain bolt and oil cap.
- Wipe up any spills and clean your tools before storing.
-
Dispose of Old Oil Properly
- Pour the used oil into a suitable container and take it to a recycling center, Yamaha dealer, or automotive store accepting used oil. Never dump oil on the ground or in the trash.
2018 Yamaha TTR110 Specific Call-Outs
- No oil filter: The TTR110 does not have an external oil filter, only an internal oil screen, so the change is a straightforward drain-and-fill process.
- Oil capacity is 28 fl oz (0.85L). Do not overfill, as this can cause engine blowby, leaks, and potentially push oil into the airbox, affecting performance. Always check oil after the bike idles and settles for accurate measurement.
- Check for leaks after tightening the drain bolt; over-tightening may strip the threads in the aluminum case. If threads are damaged, seek professional help before operating the bike.
- Clean up: Always wipe down any oil from the bike, engine and exhaust components. Oil can attract dirt and cause unpleasant smells when heated.
Tips for Best Results
- Run the bike briefly after the oil change and re-check the level as oil circulates and the level normalizes.
- Change your oil regularly, especially after dusty, muddy, or wet riding conditions. Yamaha recommends oil changes every 6 months or 1,000 miles, whichever comes first.
- Keep a maintenance log. Record the date, oil type, and hours or miles at each change for better resale value and reliability.
- Clean and store your tools after use, and wash your hands to avoid long-term skin exposure to used oil.
Proper oil changes are the single best step you can take to ensure your 2018 Yamaha TTR110 delivers reliable, fun rides for years to come. For all your maintenance supply needs, count on MotoSport.com for the best selection, fast shipping, and expert advice. Happy riding.
