Tools & Supplies Needed

  • 10mm socket or wrench (for drain bolt and oil filter cover screws)
  • Oil catch pan
  • New oil filter (specific for TW200)
  • Fresh engine oil (Yamaha recommends 10W-40 for the TW200)
  • Funnel
  • Shop towels or rags
  • Torque wrench (for precise reinstallation)
  • Pick tool or small screwdriver (to help remove the old filter)
  • New O-rings (recommended for the filter and drain plug, if available)

Yamaha TW200 Oil Change Steps

  1. Warm Up the Engine
    • Start the bike and let it run for about 3 minutes. Warm oil drains more thoroughly and carries away more debris.
  2. Prepare Your Work Area
    • Place the bike on a stable, level surface and secure it with the kickstand or a bike stand.
    • Set your oil catch pan under the engine.
  3. Remove the Oil Drain Bolt
    • Use a 10mm socket or wrench to remove the oil drain bolt located on the left side of the engine underneath the crankcase.
    • Allow all the oil to fully drain into the pan. Inspect the crush washer on the drain bolt and replace it if damaged.
  4. Clean and Inspect the Oil Drain Plug Screen
    • Take out the oil drain plug–s metal screen (if applicable) and clean it thoroughly to remove trapped debris before reinstalling it. This screen is an important safeguard for your engine against metal particles.
  5. Remove the Oil Filter Cover
    • Remove the three 10mm bolts holding the oil filter cover in place on the right side of the engine with a socket or wrench.
    • Carefully pull off the cover. A small amount of oil may leak out—have a rag handy.
    • Note the orientation of the old oil filter before removing it. Use a pick tool if needed. Be careful to retrieve the spring and O-ring behind the filter—they–re easy to lose or misplace.
  6. Replace the Oil Filter & O-Rings
    • Install a new oil filter in the same orientation as the old one (the open end faces out), and seat the spring correctly behind it.
    • If your new filter kit includes new O-rings for the filter cover and drain bolt, swap those in to ensure a leak-free seal.
  7. Reinstall Oil Filter Cover & Drain Bolt
    • Hand-thread the bolts back into the filter cover, then torque them to specification–avoid over-tightening to prevent damage to the cover.
    • Reinstall the drain bolt and torque it to spec–18 ft-lb (24 Nm) is recommended for the TW200.
  8. Add Fresh Oil
    • Double-check the drain bolt and filter cover are secure.
    • Remove the filler cap and use a funnel to add 1.1 quarts (1.0 liters) of 10W-40 motorcycle oil for a filter-and-oil change on the TW200.
  9. Check Oil Level
    • Replace the filler cap and start the engine. Run it for 1–2 minutes, then turn it off and allow oil to settle for another minute.
    • With the bike upright (not on the kickstand), check the oil level in the sight glass on the lower right side of the case–it should be between the upper and lower marks. Add oil if the level is low, but do not overfill.
  10. Reinstall Skid Plate
    • If you removed the skid plate for access, reinstall now with the original hardware.

Model-Specific Tips for the 2004 Yamaha TW200

  • The 2004 model–s oil capacity is approximately 1.1 quarts (1.0 liters) with a filter change. Overfilling can cause excess pressure and leaks, while underfilling risks engine damage. Always double-check oil level after the engine has settled.
  • The oil filter orientation is crucial: install with the open end facing out towards you. Installing backwards can restrict oil flow and damage your engine.
  • Carefully inspect and clean the oil screen strainer on the drain plug, as it traps larger particles and is easily overlooked. Replacement is generally not required unless damaged.
  • Be gentle when reinstalling the oil filter cover screws. Overtightening can strip the aluminum threads in the crankcase.
  • If your TW200 is equipped with a skid plate, it may need removal for full access to the drain bolt. Reinstall the skid plate after the oil change.

Disposal and Final Checks

  • Properly dispose of the old oil and filter at a certified recycling center or auto parts store offering oil collection.
  • After riding, check for leaks around the drain bolt and oil filter cover. Tighten if necessary, but do not overtighten.

Performing an oil change on your 2004 Yamaha TW200 is a simple yet essential part of owning and caring for your bike. Done right, it preserves your engine, maintains performance, and gives peace of mind out on every ride.
