Changing the oil in your 2021 GAS GAS TXT Racing 280 is a crucial maintenance task that ensures optimal engine performance and durability. Below are step-by-step instructions proprietary to MotoSport.com, including the tools required, key model-specific details, and tips to get the job done right.

Tools and Materials Needed

  • Socket wrench set (including the correct size for the oil drain bolt; refer to your manual for specifics)
  • Open-end wrench (right-size spanner; generally recommended to check your set for the correct fit)
  • Oil catch pan
  • Clean rags or shop towels
  • Measuring jug or graduated container
  • Funnel
  • Replacement engine oil (recommended: synthetic 10W-30 gear oil; capacity: 400-450cc)
  • Gloves and safety glasses (recommended for personal safety)

Preparation Steps

  • Warm up the engine for a few minutes. This helps the oil flow out smoothly.
  • Switch off the motorcycle and place it securely on a level stand.
  • If possible, clean the engine area around the drain plug to prevent dirt from entering the crankcase.

Oil Change Procedure

  1. Remove the Oil Drain Plug
    • Locate the oil drain bolt under the engine.
    • Position the oil catch pan directly underneath.
    • Use the correct size wrench (often 13mm or 17mm, but check your model) to loosen and remove the drain plug. Be cautious of hot oil.
    • Allow all the old oil to drain completely into the pan.
  2. Inspect the Drain Plug
    • Check the drain plug and its washer for wear or metal particles, which can indicate internal engine wear.
    • Wipe the plug clean and replace the washer if it's damaged or excessively compressed.
  3. Refit the Drain Plug
    • Install the cleaned drain plug back into position.
    • Tighten by hand, then use a wrench to snug it up. Do not overtighten–stripping the threads is a common mistake.
  4. Remove the Oil Fill Cap
    • The oil fill cap is typically found on the right side on top of the engine.
    • Open the cap and set it aside in a clean location.
  5. Add New Oil
    • Using a funnel, add 400-450cc of 10W-30 synthetic gear oil.
    • Pour slowly and use a measuring jug to ensure precise volume.
    • Allow the oil to settle for a minute, then briefly check the level as indicated in your manual.
    • Refit and tighten the oil fill cap.
  6. Final Check
    • Start the engine for a minute to circulate the new oil.
    • Shut off and let it sit. Inspect for leaks around the drain area and check oil level again; top off if necessary.

Model-Specific Notes for 2021 GAS GAS TXT Racing 280

  • Oil type and volume: The recommended oil is 10W-30 synthetic gear oil, with a fill capacity of 400-450cc.
  • Drain bolt position: Take care when locating and loosening the drain plug; clearance is tight on trials bikes, and the bolt is prone to collecting dirt. Always clean this area before removal.
  • Don’t overtighten: These drain bolts can strip easily due to the aluminum case. Hand tighten, then give a gentle snug only.
  • Air filter maintenance: This is a good time to check the air filter, as recommended by the manual. Clean, dry, and re-oil if needed.
  • Bank your old oil: Always dispose of used oil at a certified recycling center.

Pro Tips

  • If the bike is muddy or dusty, consider rinsing the area around the drain plug first to prevent debris entry.
  • Use only the recommended oil and do not overfill.
  • Check for oil leaks after your first ride post-change.
