Shop parts for a 2018 Yamaha TW200 Dirt Bike.

Changing the oil in your 2018 Yamaha TW200 is a straightforward but essential part of regular maintenance that ensures a long and healthy engine life. This guide is crafted specifically for MotoSport.com customers, providing step-by-step instructions, necessary tools, and model-specific advice to guarantee a smooth oil change process.

Tools and Materials Needed

  • 10mm socket or wrench (for removing the skid plate, if installed)
  • 17mm socket or wrench (for the oil drain bolt)
  • Torque wrench (recommended for reassembly)
  • Drain pan
  • Rags or shop towels
  • Funnel
  • New oil filter (model-specific)
  • Replacement O-rings (optional but recommended, especially for older bikes)
  • High-quality motorcycle oil (Yamaha recommends 20W-40 or 10W-40, approximately 1 liter)
  • Pick tool (optional, for removing old O-rings or cleaning the oil strainer)
  • Gloves

Preparation

  • Warm up the engine for a couple of minutes. This helps the oil flow more easily and carry away contaminants when draining.
  • Turn off the engine and make sure the bike is stable on a kickstand or center stand.

Steps to Change the Oil

  • Remove the Skid Plate (if equipped):
    • Use the 10mm socket or wrench to remove the bolts holding the skid plate beneath the engine and set it aside.
  • Clean Around the Oil Filler Cap:
    • Wipe away dirt and debris around the oil filler cap to prevent contamination when new oil is added.
  • Remove the Oil Filler Cap:
    • Unscrew the filler cap located on the right side of the engine to allow air in and help the oil drain smoothly.
  • Drain the Old Oil:
    • Place the oil drain pan under the drain bolt, which is on the bottom left side of the engine case.
    • Use the 17mm socket or wrench to remove the drain bolt. Let the oil drain completely into the pan.
    • Inspect the drain bolt's O-ring for damage and replace if necessary.
  • Clean or Replace the Oil Strainer:
    • The TW200 has a small oil strainer (metal mesh screen) in addition to the oil filter. Remove and clean it with solvent if possible.
    • Replace the strainer and O-ring if damaged.
  • Remove and Replace the Oil Filter:
    • Locate the oil filter cover near the drain bolt. Remove the three bolts holding the cover using the appropriate socket or screwdriver.
    • Remove the old oil filter. Note the direction it faces, as the new filter must go in the same way.
    • Inspect the filter cover O-ring and replace it if it's worn or damaged.
    • Install the new oil filter, reattach the cover, and tighten bolts evenly to the specified torque (typically around 7 Nm, but check your manual).
  • Reinstall the Drain Bolt:
    • Once oil is fully drained (and the strainer is clean), reinstall the oil drain bolt and washer/O-ring, tightening to the manufacturer's recommended torque (typically 43 Nm for the TW200).
  • Refill with New Oil:
    • Insert a funnel into the oil fill hole and pour in the new oil–start with 1 liter. The TW200 takes just about 1 liter; avoid overfilling.
    • Reinstall the filler cap.
  • Start the Engine and Check Oil Level:
    • Start the engine and let it idle for a minute. This circulates oil through the new filter and throughout the system.
    • Turn off the bike and let it rest for a minute, then check the oil level via the sight glass on the lower right side of the engine.
    • The oil should sit between the upper and lower marks. Add oil if necessary or drain some if overfilled.
  • Reinstall the Skid Plate:
    • If you removed the skid plate, reinstall it using the 10mm bolts.
  • Dispose of Old Oil and Filter Properly:
    • Take the used oil and filter to an authorized recycling center.

Model-Specific Call-Outs for the 2018 Yamaha TW200

  • The TW200 oil drain bolt should be torqued to approximately 43 Nm (check your owner's manual for confirmation).
  • Oil capacity is approximately 1 liter when changing both oil and filter; don't overfill.
  • Inspect the oil strainer screen for debris or damage, especially on older or higher-mileage bikes.
  • If the O-rings for the oil filter cover or drain bolt are original or visibly worn, replace them during each oil change for optimal sealing and to prevent leaks.
  • Always check the oil level via the sight glass while the bike is standing upright–not on the side stand–for an accurate reading.

Maintenance Tips and Recommendations

  • Change your oil and filter every 2,000 miles or as recommended in your owner’s manual.
  • If you ride in harsh environments (dust, mud, extreme heat), consider shorter change intervals.
  • Inspect for any oil leaks after your first ride following the oil change.
  • Keep records of oil changes for warranty, resale, and tracking maintenance intervals.
