Regular oil changes are crucial for keeping your 2011 GAS GAS EC200 transmission running smoothly and protecting internal components from premature wear. This guide, proprietary to MotoSport.com, details every tool required, each step of the process, and all key model-specific tips to ensure a clean and effective oil change for your dirt bike.

Tools & Materials Needed

  • 8mm and 10mm Allen wrenches (may vary–always check your specific bike)
  • Torx bit set (if your skid plate or drain bolt uses Torx fasteners)
  • Small funnel (the fill port is small and awkwardly placed)
  • Oil catch pan
  • Measuring cup (to precisely refill the specified oil quantity)
  • Fresh transmission oil (900ml, check your manual for type; most use a 10W-40 or 80W gear oil)
  • Clean rags
  • Rubber gloves
  • New crush washer for drain plug (recommended)
  • Torque wrench (optional but advised for proper bolt torque)

  • There are two drain plugs on the bottom of the engine. The rear drain plug is the oil drain for transmission oil. The front plug is a crankcase water drain, useful if you flood the engine during a water crossing; do not remove the front plug for a routine oil change—it's not meant for draining oil and should only be opened if you suspect water ingress in the crankcase.
  • The oil fill port is very small and awkward to access. Use a small funnel and patience to avoid spillage and mess.
  • You may need to remove the skid plate for full access. Plan to set aside extra time if you have an aftermarket pipe guard or reinforced skid plate mounted .

Step-by-step Guide: Changing the Oil

  1. Warm up the engine briefly
    • Start the bike and let it idle for 2-3 minutes. This helps the oil flow easily when draining.
    • Shut the engine off and support the bike using a stand or have it upright on level ground.
  2. Remove the Skid Plate (if equipped)
    • Use the correct size Allen or Torx wrenches to remove any fasteners securing the skid plate. Carefully set hardware aside. This improves access to the drain plug .
  3. Locate the Rear Drain Plug
    • The rear plug under the engine is your transmission oil drain plug for the EC200 . Do not confuse it with the front drain (crankcase water drain). Double-check location by referencing your owner's manual or parts diagrams if needed.
  4. Position Your Oil Catch Pan
    • Place the catch pan directly beneath the drain plug to collect all used oil.
  5. Remove the Rear Drain Plug
    • Using an Allen key, carefully loosen and remove the rear drain plug. Allow the oil to drain completely into your pan. Inspect the plug's magnetic tip for metal debris. Small flecks are normal, but larger chunks may indicate internal issues and warrant further inspection .
  6. Clean and Inspect the Drain Plug
    • Wipe the magnetic tip clean. Check and replace the crush washer, if necessary.
  7. Reinstall the Rear Drain Plug
    • Thread in the drain plug by hand, then snug it with a wrench. Do not overtighten; use a torque wrench if you have one (spec torque: refer to your manual, generally about 12-15 Nm). Confirm a tight and oil-tight seal, with no cross-threading .
  8. Remove the Oil Fill Cap
    • The oil fill plug is located on the engine case (often small and a bit awkwardly placed against frame rails). Use the correct Allen key to open it .
  9. Refill with Fresh Oil
    • Using a small funnel, pour in exactly 900 milliliters of oil (per manufacturer specification ). Pour slowly to avoid overflow or spillage, as this is easy to do with the tiny fill port .
  10. Replace the Fill Cap
    • Thread the fill cap back in and snug it up.
  11. Check for Leaks
    • Wipe down the bottom of the engine, start the bike, and let it idle for a minute. Kill the engine and check the plug area for leaks.
  12. Reinstall Skid Plate (if removed)
    • Reattach your skid plate using the original hardware.
  13. Cycle the Kickstart by Hand
    • Before starting the engine, slowly kick the starter lever a few times to help distribute oil throughout the transmission .

Additional Tips & Broader Advice

  • Record your oil change date and hours in a log for easy maintenance tracking.
  • Dispose of used oil responsibly at a certified recycling center.
  • If you find milky oil or excessive water in the system, check for leaks or consider draining the crankcase via the front plug (see manual for more details).
  • Regular changes extend transmission life–every 10-15 hours for heavy riding, or at the start/end of each riding season.

With patience and the right setup, oil changes on your 2011 GAS GAS EC200 are straightforward and highly rewarding, keeping your bike running strong for every ride.
