Keeping your 2014 GAS GAS TXT RACING 250 in top condition means regular oil changes are a must. This guide from MotoSport.com covers the full oil change process, from the tools you’ll need, to step-by-step instructions, and special tips specifically for the TXT RACING 250.

Tools and Supplies Needed

• 8mm and 10mm socket wrenches (confirm sizes with your owner’s manual in case of aftermarket parts)
• Drain pan for used oil
• Replacement oil (high-quality gear/transmission oil, recommended 0.42-0.48 quarts)
• New crush washer for drain bolt
• Clean funnel
• Shop towels or clean rags
• Contact cleaner or brake cleaner (for cleaning up any oil spills)
• Measuring cup (for accurate oil fill)
• Optional: Torque wrench (recommended to avoid overtightening the drain bolt)

Preparation

• Ensure the bike is on a stable, level surface—preferably on a stand.
• If the engine is cold, start and let it idle for 2-3 minutes to warm the oil. This ensures better draining and flushes contaminants.
• Turn off the engine and allow the bike to cool slightly before working.

Step-By-Step Oil Change Instructions

1. Locate the oil drain plug.
   • The drain plug is usually on the underside of the engine case, often facing the ground on the right side. If in doubt, refer to your owner’s manual for the exact location.
2. Place the drain pan beneath the engine.
   • Make sure the drain pan is directly below the plug to catch all used oil.
3. Remove the drain plug.
   • Use the correct size socket wrench. Loosen slowly—oil may flow out quickly.
   • Watch for the washer; don’t lose it if you plan to reuse, but a new crush washer is recommended for every change to prevent leaks.
4. Let the oil fully drain.
   • Allow several minutes for all oil to escape. Tilting the bike gently can help release any oil trapped in the case.
5. Check and clean the drain bolt.
   • Use a rag or shop towel to wipe the bolt and the drain hole, removing any metal shavings or debris.
   • Install a new crush washer on the bolt.
6. Reinstall the drain bolt.
   • Thread in by hand to prevent cross-threading, then snug with a wrench. Do not overtighten—stripping is common if too much force is used. If possible, use a torque wrench and refer to your service manual for the correct torque value.
7. Fill with fresh oil.
   • Remove the fill cap (usually on top of the engine, right side). Place a clean funnel in the opening.
   • Pour in the recommended amount (0.42-0.48 quarts for this model), using a quality gear or transmission oil designed for motorcycle use.
   • If uncertain, check the sight glass or dipstick to confirm the correct oil level.
8. Wipe down, double-check everything, and reinstall the oil fill cap.
   • Clean up any spilled oil with shop towels or contact cleaner.
9. Start the engine.
   • Run for 1-2 minutes. Shut down and wait a minute, then check for leaks around the drain bolt and fill cap.
   • Re-check oil level and top off if necessary.

Special Call-Outs for 2014 GAS GAS TXT RACING 250 Owners

• Drain plug strength: The threads on the drain plug and engine case can strip easily if overtightened. Always snug, do not force.
• Oil choice: The TXT RACING 250 works best with a high-quality 75W gear oil or a specified transmission oil. Many owners prefer a brand they’ve trusted, but always check your owner’s manual for the most accurate recommendation.
• Oil capacity: Fill with 0.42-0.48 quarts (about 400-450ml) as recommended for TXT models. Overfilling may cause excess transmission drag and clutch issues.
• Check air filter: After an oil change, take the opportunity to check your air filter as part of your regular maintenance routine.
• Environmental tip: Properly dispose of used oil at a recycling center. Do not pour down drains or onto the ground.
