Maintaining your GAS GAS TXT PRO RACING 250 with regular oil changes is crucial for performance and longevity. This guide, proprietary to MotoSport.com, provides step-by-step instructions, the tools needed, and key model-specific reminders for a smooth and thorough oil change.

Tools and Supplies Needed

  • Socket wrench and correct size socket for drain plug
  • Torque wrench
  • Drain pan
  • Clean rags
  • Measuring cup (at least 500ml capacity)
  • New crush washer (recommended)
  • Transmission oil (NILS CLUTCH TRIAL or high-quality substitute, SAE 75W as commonly used)
  • Funnel
  • Contact cleaner (optional, for cleanup)
  • Rubber gloves (optional)

Model-Specific Call-Outs

  • Oil Capacity:– 370cc (check with a measuring cup for accuracy)
  • Recommended Oil:– NILS CLUTCH TRIAL or specialist trial bike transmission/gear oil
  • Drain Plug Torque:– Avoid overtightening; too much force can strip the aluminum threads in the crankcase

Step-by-Step Oil Change Process

  1. Warm up your engine
    • Start the motorcycle and let it idle for about 5 minutes. Warm oil flows out more easily and carries away contaminants better.
  2. Secure the bike
    • Set the bike on a solid, level surface using a stand to keep it upright and stable.
  3. Locate the drain plug
    • The drain plug is typically underneath the right side of the crankcase. Refer to your owner's manual for an exact location if unsure.
  4. Place the drain pan
    • Position a drain pan under the plug to catch all the old oil.
  5. Remove the drain plug
    • Use a socket wrench to carefully remove the plug. Be mindful as oil will flow out quickly and may be hot. Allow the crankcase to drain completely.
    • Inspect the plug for any metal debris or excessive sludge; this can indicate internal wear.
    • If the crush washer looks damaged or flattened, replace it to ensure a proper seal.
  6. Clean and reinstall the plug
    • Wipe the plug and the area around the drain hole with a clean rag.
    • Install a new crush washer if available. Thread the drain plug back in by hand to avoid cross-threading, then tighten gently with a socket wrench. Do NOT overtighten. Just snug is enough – stripping the case is a costly mistake.
  7. Add new transmission oil
    • Locate the oil fill plug atop the side cover (on the right or left side depending on specific year).
    • Remove the plug, insert a funnel, and pour in 370cc of new transmission oil. Use a measuring cup for accuracy; overfilling can affect shifting and clutch feel.
  8. Reinstall the fill plug
    • Wipe any excess oil, then replace the oil filler plug and tighten securely but not excessively.
  9. Check for leaks
    • Start the engine and let it idle for a minute. Check around both the drain and fill plugs for leaks. Shut off the engine and inspect oil level if there's a sight glass or dipstick, topping off if necessary.
  10. Dispose of old oil responsibly
    • Take the used oil to a certified recycling center or auto parts shop that accepts oil.

Extra Tips and Reminders

  • If you ride in extreme conditions or frequently use the clutch (as is common in trials), inspect the oil more often.
  • Cleanliness is essential–dirt or debris around the fill or drain plug can contaminate your transmission oil.
  • Double-check the torque spec in your manual before tightening the plugs.
  • Changing the oil every 10–15 hours of ride time is generally recommended for trials bikes, depending on frequency and type of use.
