How to Change the Oil in a 2014 GAS GAS EC200

Shop parts for a 2014 GAS GAS EC200 Dirt Bike.

Keeping your 2014 GAS GAS EC200 running at peak performance means keeping up with routine maintenance like changing the transmission oil. Unlike four-strokes, this 2-stroke dirt bike doesn't mix engine oil with its fuel but uses a separate gearbox (transmission) oil that must be changed at regular intervals. This MotoSport.com guide gives you the details, tools, steps, and model-specific tips every GAS GAS EC200 owner should know.

Tools and Materials You'll Need

  • Allen wrenches (commonly 5mm and 6mm for skid plate and drain bolt)
  • Socket wrench set
  • Oil drain pan
  • Funnel (preferably with a long, skinny neck for the small fill hole)
  • Shop towels or rags
  • Transmission oil (check your owner's manual, but typically 75W or 80W gear oil is recommended, about 750-800 ml for most runs; consult your manual for exact capacity)
  • New crush washer (optional, for the drain plug)
  • Bike stand
  • Gloves

Preparation Steps

  • Warm up the engine: Let the bike idle for 3–5 minutes to warm the oil so it flows out smoothly for a more complete drain

    .
  • Secure the bike: Put the bike on a stand to keep it level and stable throughout the maintenance process.
  • Protect your workspace: Place your drain pan under the bike and have towels handy for spills.

Step-by-Step Oil Change Process

  1. Remove the skid plate.
    • You'll need access to the drain bolt, which may require removing the skid plate. Use the correct size Allen wrenches to loosen and remove the bolts holding it in place

      .
  2. Locate and remove the drain plug.
    • The drain bolt is on the bottom of the transmission case–refer to your owner's manual or look for a bolt at the lowest point.
    • Use your socket wrench or Allen key to carefully loosen and remove the bolt. Watch out for hot oil.
  3. Drain the old oil.
    • Tilt the bike slightly if needed (carefully.) to ensure a full drain

      .
    • Allow several minutes for the oil to completely drain.
  4. Inspect and reinstall the drain plug.
    • Check and replace the crush washer if necessary to prevent leaks.
    • Reinstall and tighten the drain plug to the recommended torque stated in the manual.
  5. Add new transmission oil.
    • Remove the fill plug, which is typically a small bolt on the clutch cover. The fill hole is known for being quite small and awkward to reach; use a funnel to help with pouring

      .
    • Pour in the recommended amount and type of oil. For the 2014 GAS GAS EC200, 750–800 ml of a high-quality 75W or 80W transmission oil is typical—never exceed the level marked at the fill hole or on the dipstick, if equipped

      .
    • Reinstall and tighten the fill plug.
  6. Clean up and check for leaks.
    • Wipe down any spilled oil from the engine and skid plate area.
    • Start the engine briefly and inspect around the drain and fill plugs for leaks.
    • Replace the skid plate and tighten all bolts securely.

Model-Specific Tips for the GAS GAS EC200 (2014)

  • Small fill hole: The fill plug is notoriously small and hard to access. A long, narrow funnel makes filling much easier

    .
  • Skid plate removal: On most EC-series bikes, you'll need to remove the skid plate for full access to the drain bolt. Plan accordingly.
  • Oil type: Stick to the oil weight and specification recommended in your owner's manual for the best clutch, transmission, and gear performance

    .
  • Oil volume: Do not overfill—adding too much oil can cause excess pressure and leaks

    .
  • Drain and fill locations: Make sure to identify the correct bolts; check your manual and compare to reliable online videos for confirmation

    .
  • Dispose of used oil properly: Always take your used oil to a recycling facility—never dump it in the trash or on the ground.

How Often to Change the Oil

  • Routine interval: For light trail riders, every 8–10 hours is sufficient. For racing or aggressive trail use, change the oil after every 5–8 hours of riding or after every couple of hard rides

    .

Final Tips for 2014 GAS GAS EC200 Owners

  • Regularly check oil color and level between changes—milky or darkened oil can indicate contamination or overuse.
  • During the first few oil changes, be especially mindful of what comes out. Excessive metallic particles could indicate abnormal wear and warrant further inspection.
  • Keep good records—noting the time and type of oil used can help with resale value and maintenance planning.

With these steps, products, and reminders, you can keep your 2014 GAS GAS EC200 running smoothly and reliably for every ride. For more hard-hitting how-tos and all your dirt bike parts, gear, and fluids, always trust MotoSport.com.
