Changing the oil in your 2009 GAS GAS EC200 is an essential maintenance task to keep your dirt bike running at peak performance. This guide, proprietary to MotoSport.com, provides step-by-step instructions, a list of required tools, and specific tips every EC200 owner should know to safely and effectively change the transmission oil.

Tools and Supplies Needed

  • Socket wrench (typically 13mm or 14mm, check your manual for bolt size)
  • Drain pan (to catch old oil)
  • Funnel (small and flexible for easier access)
  • Torque wrench (recommended for precise re-tightening)
  • New transmission oil (see notes below for correct type and capacity)
  • Clean cloths or shop towels
  • Nitrile gloves (optional, keeps your hands clean)
  • Parts cleaner or brake cleaner (optional, for cleaning bolt and case)

Oil Type and Capacity for 2009 GAS GAS EC200

  • Recommended oil type: Use a properly formulated transmission fluid or gear oil for two-stroke dirt bikes. Common choices are 75W-80 or 75W-90, but always confirm in your owner's manual or with a trusted supplier.
  • Oil quantity: The EC200's transmission generally takes 900 ml (0.9 liters) of oil. Do not overfill—always check the sight glass or fill to the specified level.

Steps to Change the Oil

  1. Start with a Warm Engine
    • It’s best to change the oil while it is warm (not hot). Letting the bike run for a few minutes helps the oil drain more easily.
  2. Stabilize Your Bike
    • Place the bike on a stand to keep it level and secure. This ensures complete draining.
  3. Locate the Drain Plug
    • The drain plug is typically located at the bottom of the left side of the engine case. Place the drain pan underneath the plug.
  4. Remove the Drain Plug & Drain the Oil
    • Slowly unscrew the drain bolt with your socket wrench. Let all the old oil flow into the pan.
    • If your drain bolt has a magnetic tip, inspect it for metallic debris—small particles are normal, but large chunks indicate possible damage and warrant further inspection.
  5. Inspect & Clean the Drain Bolt
    • Wipe off any metal filings or sludge from the plug, especially if it has a magnet.
    • Inspect the washer or O-ring; replace if damaged to avoid leaks upon reinstallation.
  6. Reinstall the Drain Plug
    • Hand-thread the drain bolt back in to avoid cross-threading. Then, tighten securely using a torque wrench—check your manual for the correct torque spec. The most important thing is not to overtighten and strip the threads.
  7. Refill with Fresh Oil
    • Open the fill plug located on the right side of the engine case.
    • Use a funnel for clean and spill-free pouring—this is especially helpful since access can be tight on the EC200 chassis.
    • Pour in 900 ml of new transmission oil. If your bike has a sight glass or check bolt, use it to ensure the oil is at the correct level.
  8. Double-Check for Leaks
    • With the drain plug and fill plug tightly installed, clean up any spilled oil and check around the bolt for fresh drips.
  9. Operate the Engine Briefly
    • Kick-start or turn the engine over several times (without starting if desired) to help oil circulate throughout the gearbox. This step helps distribute the fresh oil evenly.
    • Let the bike sit for a minute, then re-check the oil level and top off if needed—be careful never to overfill.
  10. Dispose of Old Oil Properly
    • Used oil must be disposed of at a recycling center or auto parts store. Never pour it down a drain or on the ground.

2009 GAS GAS EC200-Specific Call-Outs

  • The EC200 does not have a traditional oil filter for the gearbox—just drain and refill the oil as described above.
  • Be aware that overfilling can cause shifting issues or leaks from seals. Always pour in the manufacturer’s recommended amount and double-check the level by removing the check bolt or inspecting the sight glass.
  • Ensure the bike is level when checking the oil level; tilting can give inaccurate readings.
  • Magnetic drain bolts are standard and are excellent for picking up debris—inspect them carefully each oil change.
  • If you notice large particles or metallic shavings, consult a GAS GAS-certified mechanic before riding further.

Helpful Tips

  • Always use high-quality oils designed for two-stroke transmissions to maximize performance and lifespan.
  • Change your EC200’s gearbox oil every 10-15 hours of ride time, or more frequently in muddy or wet riding conditions.
  • Keep a log of your oil changes to stay on top of your maintenance schedule.

Conclusion

With the correct tools, a little patience, and an eye for detail, changing the oil in your 2009 GAS GAS EC200 is straightforward and ensures you’ll enjoy more reliable riding and longer transmission life.
