Regular oil changes are essential to keep your 2014 GAS GAS EC250ER performing at its peak. This comprehensive guide walks you through all the necessary tools, step-by-step instructions, and model-specific tips to ensure a professional-quality oil change every time. These detailed instructions are proprietary to MotoSport.com.
Tools and Supplies Needed
- Sockets and ratchet (typically 13mm or 14mm for drain plug; confirm with your bike's spec)
- Torque wrench (capable of 14.8 ft-lb)
- Oil drain pan
- New engine oil (quality 2-stroke oil as recommended by GAS GAS)
- New crush washer for drain plug
- Rags and contact cleaner for cleaning up spills
- Needle nose pliers (helpful for removing/installing the oil screen)
- New oil filter (if applicable; confirm if your model uses a replaceable filter or only a screen–refer to your owner's manual)
- Funnel or squeeze bottle with a long spout (the fill hole is recessed)
- Disposable gloves
- Flathead screwdriver (if needed for removing certain covers or the oil screen plug)
Preparation
- Warm up your bike for a few minutes to help the oil flow out more easily—just a gentle idle is sufficient.
- Put your dirt bike on a stable stand and ensure the engine is fully off and cool enough for safe handling.
- Locate the oil drain plug underneath the engine. Place your oil drain pan directly under the plug.
Step-by-Step Oil Change Instructions
- Remove the Drain Plug
Use the correct size socket and ratchet to remove the oil drain plug. Remove carefully, as hot oil will start to flow out quickly. Be sure to retain the crush washer for inspection or replacement. - Allow Oil to Completely Drain
Let the oil drain fully—tilt the bike gently from side to side to ensure all oil is out. - Remove and Inspect the Oil Screen and Oil Filter (If Equipped)
Your 2014 EC250ER may have a small oil screen that needs regular cleaning/inspection. Clean the screen with contact cleaner and check for any metal shavings, which could indicate engine wear. If your model uses an oil filter, remove it at this stage and inspect or replace with a new one. - Clean All Surfaces and Replace Seals/O-Rings
Wipe all sealing surfaces clean. Inspect O-rings and gaskets for flattening or damage—replace if necessary for a reliable seal on reassembly. - Reinstall the Oil Screen and Drain Plug
Ensure the oil screen's O-rings are lightly oiled and properly seated in their groove before installation—misalignment can allow debris into critical engine components. Use a torque wrench to tighten the oil drain plug to 14.8 ft-lb (20 Nm) to avoid stripping the threads or leaking. - Refill with Oil
The oil fill hole on the EC250ER is recessed and can be frustrating to access. Use a funnel with a narrow or flexible spout to avoid spillage. Refer to your owner's manual for the correct oil capacity. Pour in about 85–90% of the rated volume, then slowly top up as needed. - Check Oil Level
After the initial fill, wait a few minutes for oil to settle. Check the sight glass (or dipstick if equipped) with the bike upright and level. If you struggle to see the oil in the sight glass, add oil incrementally—let it settle between pours as the fill process for the EC250ER can be slow. - Inspect for Leaks and Final Steps
Start the bike briefly and check for any leaks. After idling for a minute, shut it down and let it sit for a couple of minutes. Recheck the oil level and add oil if required. If you overfilled, some oil may need to be removed (unfortunately, there is no easy “overflow” bolt like on some other makes).
Model-Specific Call-Outs for the 2014 GAS GAS EC250ER
- The oil fill port is notably recessed and can be very challenging to access without a flexible-spout funnel or squeeze bottle.
- Take extra care not to over-tighten the drain plug to avoid damaging the threads—use a torque wrench.
- Replace the crush washer and damaged O-rings when reinstalling the plug and oil screen to prevent leaks.
- Oil filling is slow on this model: add oil, allow it to settle, and repeat. Patience is key, as hasty topping up can result in overfilling.
- Inspect the oil screen carefully for metal debris, as this may indicate early signs of engine problems.
Final Tips
- Dispose of old oil and the used filter at a recycling facility.
- Keep oil changes regular—review the manual for recommended intervals based on your riding environment.
- Document the oil change date and hours for maintenance tracking.
