Shop parts for a 1993 Yamaha TW200 Dirt Bike.
Changing the oil in your 1993 Yamaha TW200 is a vital part of routine maintenance that ensures engine longevity and performance. While the TW200 is known for its reliability and easy serviceability, attending to a proper oil change requires some key tools and attention to detail specific to this model. This MotoSport.com guide walks you through every step.
Tools and Supplies Needed
- 10mm and 12mm socket or wrench
- Torque wrench (for reassembly accuracy)
- Oil catch pan
- Funnel
- New oil filter (Yamaha OEM recommended for proper oil flow)
- Fresh engine oil (Yamalube 10W-40 or comparable, approximately 1 quart / 1 liter)
- New O-ring (for drain bolt, if old one is worn)
- Rags or paper towels (for cleaning spills)
- Flathead screwdriver or pick tool (for removing the old oil filter cover)
Steps to Change the Oil
-
Warm Up the Engine
- Start the bike and let it idle for 2–3 minutes. This warms up the oil, helping it drain more completely.
- Turn off the bike and place it on a secure center stand or paddock stand.
-
Remove the Skid Plate (if equipped)
- Use a 10mm wrench or socket to remove the bolts securing the skid plate. Set the plate aside.
-
Drain the Old Oil
- Place the oil catch pan beneath the oil drain bolt (located on the left side, lower part of the engine case).
- Use a 12mm wrench to loosen and remove the drain plug. Oil will begin to drain—allow it to flow until it slows to mere drips.
- While draining, inspect the drain bolt and its O-ring. Replace the O-ring if it appears cracked or flattened to prevent leaks during reassembly.
-
Clean and Reinstall the Drain Bolt
- Clean the drain bolt and install a new O-ring if needed.
- On the TW200, the drain bolt also secures a small screen strainer and spring. Remove the strainer, clean it thoroughly with solvent, and let it dry before reinstallation .
- Reinstall the cleaned strainer, spring, and drain bolt assembly. Hand-tighten first to avoid cross-threading, then use a torque wrench to tighten to 43 Nm (32 ft-lb) .
-
Replace the Oil Filter
- The oil filter housing is found behind a round cover on the left side of the engine, secured by three bolts.
- Remove the cover bolts with a 10mm socket or wrench.
- Pull out the old filter. Clean the oil filter cavity with a clean rag. Inspect and lubricate the cover’s O-ring; replace if worn.
- Install the new oil filter with the four small holes facing outwards, towards the engine cover—this is crucial for proper oiling on the TW200 . Filters without these holes can cause catastrophic oil starvation to the top end.
- Reinstall the cover and tighten the bolts evenly.
-
Add Fresh Oil
- Remove the oil fill cap on top of the clutch cover. Using a funnel, pour in approximately 1.0 liter (1.06 US qt) of fresh oil .
- Replace the oil fill cap.
-
Check Oil Level and Final Steps
- Start the engine and run it for 1–2 minutes to circulate the new oil. Turn off and let the bike sit for another minute to allow oil to settle.
- Check the oil level using the sight glass located on the lower right side of the engine. The oil should be between the upper and lower marks.
- If needed, add or remove oil to reach the correct level .
- Reattach the skid plate.
- Inspect for leaks around the oil filter cover and drain plug areas after your first ride.
Important Model-Specific Call-Outs for the 1993 Yamaha TW200
- Oil Filter Orientation: Always install the oil filter with the four small holes facing out (towards the cover). An incorrectly oriented or aftermarket filter lacking these holes can halt oil flow to the top end, leading to major engine failure .
- Oil Strainer Screen: Clean the strainer screen and inspect the O-ring and spring every oil change. This is a critical, but often overlooked, step for long-term engine health .
- Drain Bolt Torque: Do not overtighten. Always use a torque wrench set to 43 Nm for the drain bolt on this model to avoid damaging the crankcase threads .
- Skid Plate Removal: The stock TW200 skid plate makes drain plug access challenging; always remove the plate for quick, mess-free oil changes .
- Oil Level Check: The TW200 does not have a dipstick. Always check using the sight glass while holding the bike upright and level .
Wrapping Up
Changing the oil in your 1993 Yamaha TW200 is a straightforward task with the right tools, methodical approach, and attention to detail.
