Maintaining your 2017 GAS GAS TXT PRO RACING 280 is crucial for ensuring its longevity and optimal performance on the trails. One of the most essential maintenance tasks is changing the engine oil on schedule. Below you'll find everything you need—tools, step-by-step instructions, and model-specific tips—to complete this job confidently and correctly. This guide is written exclusively for MotoSport.com customers who want precise care for their dirt bike.

Tools & Supplies Needed

  • Socket set (with 8mm and 10mm sockets)
  • Box-end wrenches
  • Drain pan (oil catch container)
  • Clean funnel
  • Rubber gloves (recommended for cleaner hands)
  • Rags or shop towels
  • OEM recommended gear oil (see your owner's manual for specifications—generally a quality 75W transmission oil is suitable, but always verify for your climate and riding style)
  • Replacement crush washer (recommended, optional)
  • Parts cleaner (optional, for extra cleanliness)

Preparation Steps

  • Ensure the motorcycle is on a level surface using a secure bike stand for stability.
  • Start and warm up the engine for a few minutes. Warm oil drains more quickly and removes more contaminants.
  • Turn off the engine and let it rest for a few minutes to avoid getting burned by hot components.

How to Change the Gear Oil: Step-By-Step Instructions

  1. Locate the Oil Drain Plug:
    On the 2017 GAS GAS TXT PRO RACING 280, the oil drain plug can be found at the bottom of the engine case. You may want to reference the owner's manual or look just behind the crankcase on the left side. Place your drain pan directly underneath this location.
  2. Remove the Oil Fill Plug:
    This is typically on top or the side of the engine case. Removing it before draining helps the oil flow out smoothly by allowing air in.
  3. Loosen and Remove the Drain Plug:
    Use your socket or appropriate wrench to carefully loosen, then remove the drain plug. Let the oil flow completely into your drain pan. Inspect the drain plug for any metal shavings or debris, which could indicate abnormal internal wear.
  4. Replace the Crush Washer (If Applicable):
    Inspect the crush washer for wear or damage. A new washer helps ensure a proper seal and prevent leaks.
  5. Reinstall and Tighten the Drain Plug:
    Hand thread the plug first to avoid cross-threading, then snug it up with your wrench. Do not over-tighten—consult your manual for torque specifications. Over-tightening can strip the threads in the engine case.
  6. Add Fresh Gear Oil:
    Insert a clean funnel into the fill hole. Pour in the manufacturer-specified oil type and quantity (usually around 380cc for this model; double-check your owner's manual or on the clutch cover where the capacity may be marked) through the funnel. Go slow; do not overfill.
  7. Check Oil Level:
    Most GAS GAS TXT models have a small bolt or “inspection check hole” on the right side case—oil should just begin to seep out when the bike is level and the correct amount is in. Alternatively, check the sight glass if equipped.
  8. Replace the Fill Plug:
    Screw the fill plug back on and snug it up.
  9. Wipe Up and Check for Leaks:
    Wipe off any spills around the fill and drain locations. Start the bike and let it run for a minute, then inspect for oil leaks. Re-tighten as needed.
  10. Dispose of Old Oil Properly:
    Take your used oil to a recycling center according to local regulations.

Model-Specific Call-Outs for the 2017 GAS GAS TXT PRO RACING 280

  • Oil Type: Use the transmission oil recommended by GAS GAS. While many use a 75W gear oil, refer to your owner's manual for exact specs and volume since different riding temperatures may warrant special oil weights.
  • Drain Plug Location: GAS GAS positions the drain plug for easy access, but it is typically small; take care not to overtighten.
  • Oil Level Check: This model doesn't have a dipstick. Ensure to use the fill/check bolt method for accurate measurement. Overfilling can cause clutch drag; too little can damage gearbox components.
  • Change Interval: GAS GAS recommends changing the gear oil every 20 to 30 hours of use, or after particularly heavy riding conditions for best clutch and gearbox life.
  • Clutch Performance: Many owners note the clutch feel can change radically with oil type and even after one ride, so regular changes with high-quality oil can noticeably improve shifting and clutch life.

Troubleshooting and Additional Tips

  • If the oil is milky, you may have water contamination and should inspect the water pump seals.
  • Do not reuse old oil—it loses lubricity and contaminants build up over time, degrading engine performance and lifespan.
  • Dispose of all oil according to local, state, or federal regulations.

Regular oil changes are the best investment in smooth shifting and long engine life for your 2017 GAS GAS TXT PRO RACING 280. For all your parts, fluids, and exclusive dirt bike maintenance tips, trust MotoSport.com.
