Keeping your GAS GAS EC200R running reliably and at peak performance means sticking to a strict oil change schedule. With the right tools and instructions, you can handle this crucial maintenance at home. At MotoSport.com, we know every bike has unique quirks—especially the trusted EC200R. Here–s everything you need to perform a safe, thorough oil change on your 2014 GAS GAS EC200R.

Tools and Materials Needed

  • 10mm and 13mm socket/wrench (for drain bolt and other fasteners)
  • Flathead screwdriver (to loosen drain plug if needed)
  • Drain pan (with a capacity for at least 1L)
  • Funnel (narrow tip recommended for gearbox fill port)
  • Motorex Cross Power 2T / appropriate 2-stroke transmission oil (see owner–s manual; most models require 900ml)
  • New OEM oil filter (only if specified in your model year; most two-strokes like the EC200R do not use a replaceable oil filter)
  • New drain bolt crush washer (recommended for leak prevention)
  • Shop rags or paper towels
  • Torque wrench (for precision reassembly)
  • Gloves (for skin protection)

Important Model-Specific Callouts (2014 GAS GAS EC200R)

  • Transmission Oil: The EC200R uses a separate transmission oil, not mixed with the 2-stroke fuel. Use only designated gearbox oil to avoid clutch issues and ensure smooth shifting.
  • Oil Quantity: Typical fill for this two-stroke transmission is 900 ml—check the sight window or fill port on your engine for confirmation.
  • No Regular Oil Filter: Unlike four-stroke engines, the EC200R does not require a standard replaceable oil filter.
  • Drain and Fill Locations: The oil drain bolt is on the underside of the crankcase; the fill plug is on the right side cover.
  • Check for Metal Debris: The EC200R usually has a magnetic drain plug. Small metal particles are normal; large chunks may signal serious issues and require further inspection.

Step-by-Step Oil Change Procedure

  1. Warm up the Engine
    • Let your bike idle for 2-3 minutes. This helps suspend contaminants in the oil so they–ll drain out with the old fluid.
    • Never change oil with a hot engine—let it cool enough to avoid burns.
  2. Stabilize Your Bike
    • Place the bike on a stand or level ground for safety and proper drainage.
  3. Remove the Oil Drain Bolt
    • Locate the transmission drain bolt on the bottom of the right crankcase.
    • Use a 13mm socket or wrench to loosen and remove the plug. Be careful; oil drains rapidly.
    • Allow the oil to empty fully into the drain pan. Inspect for excessive metal shavings on the magnetic plug.
  4. Replace the Crush Washer
    • Remove and discard the old crush washer. Install a new one on the drain bolt for a proper seal.
  5. Reinstall the Drain Bolt
    • Clean the bolt and mating surface. Reinstall the plug by hand, then torque to manufacturer spec (usually 10-15 Nm; consult your manual).
  6. Remove the Oil Fill Plug
    • The fill cap is found on the right-hand side cover of the engine. Use a 10mm wrench or socket if necessary.
  7. Add Fresh Transmission Oil
    • Insert a funnel. Pour in 900 ml of high-quality 2-stroke transmission oil. Avoid overfilling—too much oil causes pressure issues and leaks.
    • Use the sight window (if equipped) to monitor level. Stop at the recommended mark.
  8. Reinstall the Fill Plug
    • Hand-tighten, then snug with the wrench. Inspect for leaks beneath the bike.
  9. Cycle the Engine
    • Kick-start the bike (without actually starting) several times to circulate oil through the transmission gears and clutch plates.
    • Start the engine and allow it to idle; then shut down and check for leaks or drips again.
  10. Dispose of Oil Responsibly
    • Pour used oil into a proper container and bring it to a recycling center or hazardous waste facility.

Pro Tips

  • Use the best-quality oil you can find to prevent clutch slip and gearbox wear.
  • Inspect the magnetic drain plug every oil change to monitor engine health—tiny metal flakes are normal, but fragments or chips warrant a closer look at your transmission components.
  • If shifting feels rough after an oil change, make sure the correct quantity and specification oil was used.
  • Always clean up spills and keep your work area tidy for maximum safety.
