How to Change the Oil in a 2023 GAS GAS TXT GP 250

Keeping your 2023 GAS GAS TXT GP 250 in top working condition demands regular maintenance, and regular oil changes are essential for the longevity and performance of your bike. At MotoSport.com, our experts have assembled a detailed, model-specific how-to guide for changing the oil on your TXT GP 250, including the tools you'll need, the steps you must follow, and special callouts specific to this trials bike.

Tools and Supplies Needed

  • Socket wrench or spanner set (confirm the correct size for your drain and fill plugs–commonly 13mm or 17mm, but verify against your model)
  • Drain pan
  • Replacement crush washer (recommended for every oil change)
  • Funnel
  • Clean rags or shop towels
  • Contact cleaner (optional, for cleaning up oil drips and surfaces)
  • Fresh oil (refer to your owner's manual for the correct grade and quantity–commonly high-quality synthetic 2-stroke gear oil or 10W-40/10W-30, approximately 400-500ml, but confirm your manual for 2023 model exact spec)
  • Oil container for recycling old oil
  • Measuring cup (helpful for precise oil fill)
  • Gloves (optional, for keeping hands clean)

Changing the Oil—Step-by-Step Process

  • Warm up the engine: Start and run your engine for a few minutes to allow the oil to warm up. Warm oil drains more thoroughly and carries away more contaminants. Turn off the engine before you start.
  • Position the bike securely: Place your TXT GP 250 on a stable stand so the bike is upright and level. This ensures all oil drains out and makes refilling easier.
  • Clean around the drain plug: Use a clean rag to wipe any dirt or debris from around the oil drain bolt to prevent contamination when it's removed.
  • Place the drain pan under the engine: Make sure the pan is directly underneath the drain bolt to catch all the used oil.
  • Remove the oil drain plug: Use the correct size wrench or spanner to gently loosen and remove the drain bolt. Do not overtighten when reinstalling–stripped threads are a common issue if overtightened.
    Specific call-out: Owners report stripped threads if over-tightened–just snug, not tight. Replace the crush washer with every oil change for a proper seal and to avoid leaks.
  • Allow all oil to drain: Give it plenty of time to fully drain. Tilting the bike gently side to side can help remove every drop.
  • Inspect the drain plug and crush washer: Clean the drain bolt and inspect or replace the crush washer as needed.
  • Reinstall the drain plug: Thread the bolt in by hand to avoid cross-threading, and then snug it gently with your wrench–do not over-tighten. A torque setting of around 10-12 Nm is typical, but check your manual for the exact spec.
  • Add fresh oil: Remove the filler cap. Use a funnel and measuring cup to pour the exact amount of recommended oil. Overfilling can cause problems, so be precise.
    Owner tip: Many TXT GP 250 owners prefer Synthetic (API GL-4/GL-5) 75W transmission oil or high-end 10W-40/10W-30 oils; GRO, Motul, and similar brands are popular. Again, confirm with your manual, as oil capacity and type can slightly vary by year.
  • Reinstall the fill cap: Secure and snug–do not over-tighten.
  • Check for leaks: Wipe everything clean, start the engine, and let it idle for a minute. Inspect the drain and fill plugs for any seepage.
  • Dispose of old oil properly: Pour the used oil into a recycling container and dispose of it in accordance with local environmental regulations.

Model-Specific Callouts for the 2023 GAS GAS TXT GP 250

  • Crush Washer Care: Never reuse the old washer; leaks may occur with repeated use. This is particularly important for GAS GAS models due to the soft alloy and fine thread pitch.
  • Avoid Over-Tightening: TXT GP motors are known for easily stripped drain plug threads–snug is enough.
  • Oil Capacity and Type: While 400-500ml is typical for TXT GP trials bikes, always refer to your service manual for the precise spec. Variations in clutch and gearbox designs mean oil types and capacities may slightly differ–contact a MotoSport.com technician if unsure.
  • Cleaning Is Critical: Trials bikes tend to pick up a lot of debris around the drain area. Don't skip prep cleaning–the last thing you want is sand or grit in your transmission.

Extra Pro Tips from MotoSport.com

  • Always change oil after every 15 hours of riding or after heavy use, whichever comes first.
  • Use contact cleaner and rags to thoroughly clean surfaces before reinstalling parts for easier inspection and professional results.
  • If you ride in muddy or very wet conditions, consider even more frequent oil changes to prevent clutch wear and corrosion.
  • Keep a log of your oil changes for service tracking and warranty protection.
