- Drain pan for used oil
- Measuring cup or oil jug with markings
- Rags or paper towels
- New transmission oil (consult the manual for the correct specification; usually 10W-40 or 75W gear oil, non-synthetic is commonly recommended for two-strokes)
- Funnel (helps to prevent spills)
- Gloves (optional, for cleanliness)
- Parts cleaning brush (optional, for cleaning bolt and area around drain hole)
Important Model-Specific Call-Outs
- The 2008 GAS GAS EC200 is a two-stroke enduro model with a separate gearbox oil system; oil does not lubricate the top end like in four-strokes, so transmission oil changes are simple, quick, and should be performed regularly for the best clutch and transmission life.
- Frequency: The official manual recommends changing the transmission oil every three fuel fill-ups for the EC200.
- No traditional oil filter: Most two-stroke models, including the EC200, don't have a spin-on or cartridge oil filter like four-strokes. That means oil changes are quick, but cleanliness is very important.
Step-by-Step Guide
-
Warm Up the Engine (Optional)
Start the engine and let it idle for a minute or two. This helps the oil to flow more freely and carry away contamination. Shut the engine off and let it cool for a couple minutes to avoid burns. -
Position the Bike
Place your EC200 upright on a center stand or suitable lift stand to keep it level. Set your drain pan beneath the drain bolt on the bottom of the transmission case. -
Remove the Drain Bolt
Use the appropriate socket (verify if it's 13mm or 17mm for your specific EC200, as this can vary) to remove the oil drain bolt. Be careful, as the oil might still be hot enough to burn.- If your bolt has a sealing washer, be sure it's in good condition. Replace if damaged or crushed.
-
Let the Oil Drain
Allow all the oil to drain out completely. Lean the bike gently side-to-side if needed to help remove the last bit of old oil. -
Inspect and Clean
Wipe the drain bolt, especially if it has a magnet (to catch metal debris). Clean any residue from the threads and the area around the drain hole. Check for any metal shavings or unusual debris in the old oil–small flecks are normal, but excess metal can spell trouble. -
Reinstall the Drain Bolt
Thread the clean drain bolt back in by hand, then finish tightening it with your socket. Do not overtighten—consult your manual for torque specs if needed (approx. 15-20 Nm is typical for this type). -
Refill with New Oil
Remove the transmission oil fill cap (usually located on the right side engine case). Add the recommended amount of oil using a measuring cup or oil jug with markings. For the 2008 EC200, this is usually 700-750 ml (always confirm with your owner's manual for the exact amount).- Tip: Use a funnel and pour slowly to prevent overfilling.
- Wait a few minutes for the oil to settle, then check the oil level (some EC200 models have a sight glass; otherwise, use the dipstick if equipped, or fill to just below the bottom of the oil fill threads as specified).
-
Reinstall the Fill Plug
Hand tighten the filler cap back in place. -
Wipe Down and Inspect
Clean up any spilled oil and check for leaks around the drain bolt and fill cap. -
Dispose of Old Oil Properly
Take your used oil to a proper recycling facility. Do not pour oil down drains or onto the ground. -
Test Ride
Start your engine and let it idle for a few minutes. Check again for any leaks. Shift through the gears and ensure smooth operation.
Expert Tips for 2008 GAS GAS EC200 Owners
- Two-stroke clutches are sensitive to oil quality–use the specified oil weight and type to maintain shift quality and longevity.
- If your bike is used in muddy or wet conditions, consider changing the oil more frequently. Water ingress into the gearbox oil is a common issue for enduro riders.
- Always check the condition of your drain bolt's sealing washer and replace it when necessary to prevent leaks.
- Regular oil changes will also provide an opportunity to check for early signs of engine/transmission wear by checking for excessive metal in the drained oil.
Conclusion
Changing the oil on your 2008 GAS GAS EC200 is a quick, inexpensive job that's crucial for extending the life of your transmission and clutch. With regular maintenance and attention to correct oil type and refill intervals, your EC200 will reward you with smooth performance on the trail.
