If you ride a 2000 Yamaha TW200, routine oil changes are one of the most critical maintenance tasks to keep your bike running strong for years to come. This step-by-step guide from MotoSport.com covers all the details, tools, and model-specific pointers you need to perform a proper oil change on your TW200.

Tools and Materials Needed

  • 17mm or 19mm socket/wrench (for drain plug–confirm size as minor changes may occur across years)
  • 10mm wrench (for side cover bolts if inspecting oil filter screen)
  • Oil catch pan
  • Funnel
  • New engine oil (Yamaha recommends 10W-40, quantity about 1 liter or 1.1 US qt for the 2000 model)
  • Replacement oil filter (if changing, recommended every couple of oil changes)
  • Replacement O-rings (recommended to replace the drain plug and cover O-rings if worn)
  • Rags or shop towels
  • Torque wrench (optional, for precise tightening)

Step-by-Step Process

  1. Warm up the engine
    • Run your TW200 for about 2-3 minutes. Warm oil flows better and drains more thoroughly, removing more debris.
  2. Remove the skid plate
    • Using the appropriate wrench, unbolt the skid plate to access the oil drain plug. Set the hardware aside for reassembly. This step is essential on the TW200 as the plate blocks direct access to the drain plug.
  3. Unscrew the oil fill cap
    • Located on the right side of the engine, twist it off and rest it loosely in place. This allows the oil to drain freely without creating a vacuum in the crankcase.
  4. Drain the old oil
    • Locate the drain plug at the lowest point of the engine (bottom left area beneath the crankcase).
    • Carefully use your socket or wrench to loosen and remove the drain plug.
    • Oil will begin to flow out; be ready with the catch pan directly beneath.
    • Allow several minutes for the oil to finish draining completely.
  5. Remove and Inspect the Oil Filter and Spring
    • The TW200 features a reusable mesh oil filter (screen) held in place by a spring behind the drain plug. Note orientation for proper installation—the filter goes in first, then the spring.
    • If replacing, install the new filter. If cleaning, flush the mesh with a solvent or brake cleaner and dry thoroughly.
    • Inspect the O-ring on the drain plug for cracks. Replace the O-ring if necessary to prevent leaks.
  6. Reinstall the Drain Plug, Spring, and Oil Filter
    • Reinsert the mesh filter and spring into the correct order in the casing.
    • Reinstall the drain bolt and tighten securely. If using a torque wrench, torque to the manufacturer’s spec (typically around 21 ft-lb for the TW200; check your owner’s manual).
  7. Refill with New Oil
    • Use a funnel to add fresh 10W-40 motorcycle oil into the oil fill opening.
    • Add roughly 1 liter (1.1 US qt). Go slow and periodically check the level using the sight glass located near the right footpeg.
    • The oil level should be between the upper and lower marks on the sight glass when the bike is upright and on level ground.
  8. Run the Engine and Recheck the Level
    • Replace the oil fill cap, then run the engine for one minute. Shut off the engine and let it stand for a minute so oil can settle.
    • Double-check the oil level in the sight glass. Add more oil if needed to reach the correct range.
  9. Reinstall the Skid Plate
    • Once the oil level is correct and no leaks are apparent, replace and tighten the skid plate securely.
  10. Clean Up and Inspect
    • Wipe up any spilled oil. Dispose of used oil and filter in accordance with local regulations.
    • Check for drips or leaks under the bike after your first ride.

  • Oil Capacity: 1.1 US quarts (1.0 liter) with oil filter clean/replacement.

  • Sight Glass: The oil level is checked via a circular sight glass on the right side of the engine. Always check with the bike upright and level, not on the side stand.
  • O-Rings: If the drain plug O-ring or the cover O-ring shows any signs of distortion, flattening, or age, replace them to prevent oil leaks.
  • Recommended Oil Change Interval: Yamaha suggests changing the oil every 4,000 km (2,500 miles) for routine use, but many riders prefer to change every 2,000 miles for best engine longevity.
