Shop parts for a 2019 GAS GAS XC250R Dirt Bike.
Maintaining your 2019 GAS GAS XC250R with regular oil changes is key to ensuring peak performance and engine longevity. This guide, exclusive to MotoSport.com, details everything you need to know to confidently change your bike's oil, including model-specific tips, the tools required, and a step-by-step process for the XC250R.
Tools and Supplies Needed
- 13mm socket or 13mm open/box wrench
- T30 Torx bit (socket-type preferred for better handling)
- Drain pan (sized to hold up to 2 liters of oil)
- New oil filter (OEM or equivalent for XC250R)
- Fresh engine oil (refer to your owner's manual for type and volume, typically full synthetic 10W-50 for similar GasGas models)
- Clean rags for wiping and cleaning up spills
- Contact cleaner (fast-evaporating, non-residue type recommended)
- Torque wrench (to properly tighten drain bolt and oil filter cover)
- Replacement O-rings or crush washers for plugs, if needed
- Nitrile gloves (optional, for cleanliness and protection)
Before You Start
- Be sure your engine is warm (not hot)–run it for a few minutes. Warm oil drains faster and more completely.
- Set the bike on a stand that does not block access to the drain plug, and keep the bike as upright as possible for thorough draining.
Step-by-Step Process
-
Remove the Skid Plate (if equipped):
- If your XC250R has a skid plate obstructing the oil drain bolt, remove it for better access.
-
Position the Drain Pan:
- Place your drain pan directly below the drain bolt, which is located on the bottom of the engine case.
-
Remove the Oil Drain Plug:
- Use a 13mm socket or wrench to carefully loosen and remove the drain bolt.
- Allow the oil to drain completely–this may take several minutes.
- Inspect the drain bolt's magnet for any metal shavings or debris. A few small flecks are normal, but an accumulation of large pieces could indicate internal engine wear and should be monitored.
“There's a magnet on the bottom there... going to attract some stray metal pieces...”
-
Clean and Replace the Crush Washer/O-Ring:
- Wipe down the drain bolt and replace the crush washer or O-ring with a new one if it appears damaged or excessively flattened, which helps prevent leaks.
-
Remove and Replace the Oil Filter:
- Locate the oil filter cover (usually held in place with T30 Torx bolts).
- Remove the bolts using your T30 Torx bit.
- Remove the filter–if it's stubborn, use pliers as needed.
- Wipe the inside of the oil filter cavity clean.
- Inspect both the O-ring on the filter cover and the filter itself. Replace the O-ring if damaged or flattened.
- Install a fresh, appropriate oil filter for the XC250R.
-
Clean Drain Bolt, Oil Filter Cover, and Filter Screens:
- Spray the drain bolt, oil filter cover, and any screens with contact cleaner and wipe thoroughly.
- If your model has oil screen(s), remove, inspect for debris, clean with contact cleaner, and reinstall when dry.Gently wipe the sealing areas with a clean rag to ensure a leak-free fit on reassembly.
-
Reinstall Drain Bolt and Oil Filter Cover:
- Install the drain bolt first and tighten to manufacturer torque specs (approximately 14.8 ft-lbs for similar GasGas models).
- With fresh engine oil on the new O-rings, reinstall the filter cover and torque the bolts evenly and to specification.
-
Refill Engine with New Oil:
- Add new oil through the fill port (refer to owner's manual for exact volume; typical fill is 0.90 to 1.0 liters for GasGas/KTM 250 2-stroke models).
- Pour slowly, checking sight glass or dipstick to ensure you reach, but do not exceed, the correct oil level.
-
Start and Check for Leaks:
- Start the bike and let it idle for 2-3 minutes.
- Check oil level again and top off if needed (oil often settles after the initial run). Wipe around all mating surfaces to check for leaks.
-
Dispose of Old Oil Properly:
- Take your used oil and filter to a recycling center or an appropriate disposal facility.
Model-Specific Notes and Callouts for 2019 GAS GAS XC250R
- Drain plug and oil filter locations are similar to KTM/Husqvarna 250 models.
- Be aware that the drain bolt's magnet is there to catch debris–always check it for abnormal amounts of metal when changing oil.
- Use only manufacturer-recommended oil type and viscosity to maintain optimum clutch and engine performance.
- If your dirt bike uses a non-integrated stand, ensure you do not obstruct the drain bolt, as a standard platform stand can block access for draining and skew oil levels.
- Carefully inspect all O-rings and crush washers for damage and replace as needed.
Final Tips
- Keep a maintenance log with date, hours, and oil type used for future reference.
- Replace the filter every oil change to maximize engine protection unless otherwise specified in your manual.
- Always verify your torque specs and oil capacity against the most current OEM manual for your model year.
Completing your oil change on the 2019 GAS GAS XC250R not only ensures smoother rides, but also preserves engine life and maximizes your dirt bike's performance for years to come.
