Keeping your 2024 GAS GAS TXT RACING 250 running at peak performance starts with regular oil changes. This guide, proprietary to MotoSport.com, thoroughly covers every step you need to confidently change the oil in your dirt bike. As with any mechanical maintenance, always check your owner's manual for model-specific guidelines and torque specs before beginning.

Tools & Materials Needed

  • Socket set (ensure you have the correct size for the drain bolt; a spanner may be needed for the TXT series)
  • Oil drain pan
  • Rags or shop towels
  • Measuring cup (for precise oil fill)
  • Torque wrench (to avoid overtightening)
  • Replacement crush washer (recommended with each oil change)
  • New oil filter (if model equipped with replaceable filter; some trials bikes use only screens – check manual)
  • Contact cleaner
  • High-quality gear oil (see owner's manual; typical fill capacity for the TXT 250 is 0.42–0.48 quarts)
  • Funnel
  • Gloves

Step-by-Step Oil Change Process

  1. Warm Up the Engine
    Briefly run your bike for a few minutes to allow the oil to warm up and flow more easily. Do not overheat.
  2. Stabilize and Prepare the Bike
    Place the bike on a secure stand with the frame level. Clean the surrounding area, especially near the drain plug and filler cap, to prevent dirt from entering the engine during the oil change.
  3. Remove the Skid Plate (If Installed)
    Many TXT 250 models do not have a wide skid plate, but if yours does, remove it now to access the drain plug.
  4. Drain the Old Oil
    • Locate the oil drain bolt, typically on the underside of the engine casing.
    • Place your drain pan underneath and ensure you have the correct-size spanner or socket.
    • Loosen the drain bolt carefully. Watch for the crush washer; replace if it's worn or damaged.
    • Allow oil to completely drain — tipping the bike gently side-to-side ensures full drainage.
    • Use a clean rag to wipe any dirt or residue around the drain area.
  5. Replace the Crush Washer and Install the Drain Bolt
    • Install a new crush washer on the drain bolt.
    • Hand-thread the drain bolt to avoid cross-threading, then snug with a wrench.
    • Tighten to the torque specification provided in your manual (avoid overtightening – it's easy to strip these bolts).
  6. Oil Filter/Screen Maintenance
    • The TXT 250 uses an internal oil screen; some models may have a small replaceable cartridge filter.
    • Remove and clean the oil screen if equipped. Inspect for debris that could indicate wear or mechanical issues.
    • Replace the filter if your TXT 250 uses one.
  7. Add Fresh Oil
    • Refer to your manual for the correct oil type and volume. The TXT RACING 250 generally takes 0.42–0.48 quarts of a high-quality gear oil suitable for wet clutch systems. Popular choices include dedicated transmission or gear oil blends for trials bikes.
    • Using a funnel, slowly pour the new oil into the fill port. Do not overfill.
  8. Check Oil Level
    • Allow the oil to settle for a minute, then check the oil level using the sight glass or dipstick (if equipped).
    • Add a small amount if needed, but do not exceed the maximum fill line.
  9. Reinstall Parts and Clean Up
    • Reinstall the skid plate if you removed it.
    • Clean any spilled oil from the cases and floor using a contact cleaner and rag.
    • Dispose of the old oil properly at a recycling center.
  10. Run the Engine and Final Inspection
    • Start the bike and let it idle briefly, then shut off.
    • Check below for oil leaks at the drain plug and around the filter/screen.
    • Recheck oil level and top off if necessary.

Important Model-Specific Call-Outs

  • Drain Plug Location: The 2024 TXT RACING 250 continues the tradition of a low-slung drain plug; ensure correct washer and careful torque due to softer aluminum casings. Over-tightening can strip threads easily.
  • Oil Capacity: Factory specification is 0.42–0.48 quarts. More oil is not better — too much can cause clutch drag and shifting issues.
  • Oil Type: Trials bikes require low-friction, gearbox-rated oils compatible with wet clutches. Avoid generic automotive oils. Most owners prefer specialist gear oils (such as GRO or Motul Transoil), but double-check your manual before use.
  • Service Interval: Oil should be changed every 15 hours of use under average conditions; extreme environments may require more frequent changes.
  • Filling Port: Filler cap placement can make pouring messy—use a funnel to avoid spilling oil onto the engine or cases.

Pro Tips

  • Always use a new crush washer to prevent leaks.
  • If you notice metallic debris in your old oil, consult a technician—this could indicate internal engine wear.
  • Check the air filter after an oil change; a dirty filter can shorten your oil's lifespan.
  • Tightening bolts “snug” means a gentle touch—many beginner mistakes involve over-tightening.

Regular oil changes are the backbone of a reliable trials bike. With this guide from MotoSport.com, your 2024 GAS GAS TXT RACING 250 will stay running strong on every section and adventure.
