This guide is proprietary to MotoSport.com. We'll walk you through a complete oil change for the 2019 Honda CRF250L Rally ABS, highlighting essential tools, step-by-step instructions, and model-specific call-outs.

Tools and Supplies Needed

  • 8mm and 12mm sockets (preferably deep-well)
  • Ratchet
  • Allen key (for skid plate removal, if equipped)
  • Torque wrench (optional for accuracy)
  • Oil drain pan
  • Funnel
  • Paper towels or clean rags
  • Rubber gloves (optional but recommended)
  • Contact cleaner (for cleaning surfaces)
  • Replacement oil filter (Honda OEM or equivalent, e.g., Hiflofiltro HF112)
  • Replacement crush washer (for drain bolt, recommended to replace every oil change)
  • Replacement oil filter gasket (recommended by Honda)
  • SAE 10W-30 engine oil (Honda GN4 10W-30, requires 1.6 quarts)

Preparation

  • Park the motorcycle on a level surface and engage the side stand. Ensure the bike is stable to prevent tipping.
  • Start the engine, let it idle for 3-5 minutes to warm up the oil, then turn it off. Warm oil drains easier and carries more contaminants out.
  • If equipped with a skid plate (stock or aftermarket), remove it using the appropriate Allen key or socket for easier access.
  • Place the oil drain pan beneath the engine's drain bolt.

Step-by-Step Oil Change Process

  1. Remove the Oil Fill Cap:
    • Clean the area around the oil fill cap with contact cleaner and a rag to prevent dirt from falling inside.
    • Unscrew and set aside the oil fill cap to allow the oil to drain smoothly.
  2. Drain the Engine Oil:
    • Using a 12mm socket, remove the oil drain bolt and crush washer located on the bottom of the engine.
    • Allow all oil to drain completely into the pan. Inspect the old oil for metal shavings or debris.
  3. Replace the Crush Washer:
    • Honda recommends replacing the crush washer at every oil change for a good seal. While some riders reuse it occasionally, for longevity and to avoid leaks, a new washer is best.
  4. Remove the Oil Filter:
    • Use an 8mm socket to remove the three oil filter cover bolts.
    • Carefully remove the oil filter cover, ensuring you retain the spring and gasket.
    • Pull out the oil filter. Inspect the rubber gasket on the cover—for most oil changes, it’s replaced for optimal sealing.
  5. Install the New Oil Filter:
    • Insert the new filter, rubber side out (facing away from the engine).
    • If replacing, fit the new gasket onto the cover.
    • Reinstall the spring, then carefully fit the cover and torque the bolts evenly to manufacturer spec (typically hand-tight plus 1/8 turn).
  6. Reinstall the Drain Bolt:
    • Install the new or cleaned drain bolt with fresh crush washer.
    • Tighten to 24 Nm (18 lb-ft) with a torque wrench if available.
  7. Refill Engine Oil:
    • Place a funnel in the oil fill port and pour in 1.6 quarts of SAE 10W-30 motorcycle oil (JASO MA, API SG or higher, such as Pro Honda GN4 10W-30).
    • Replace the fill cap.
  8. Start the Engine and Check Oil Level:
    • Start the motorcycle and let it idle for 2-3 minutes, checking carefully for leaks around the drain bolt and filter cover.
    • Shut off the engine and let the oil settle for at least 30 seconds. Hold the bike upright and check oil level at the inspection window or dipstick, per the owner’s manual. Add oil if necessary.
  9. Reinstall Skid Plate:
    • Reattach the skid plate if applicable, tightening all fasteners securely.

Important Model-Specific Callouts for 2019 CRF250L Rally ABS Owners

  • Change Interval: Honda recommends changing the oil every 8,000 miles or 12 months, whichever comes first, but more frequent changes (every 4,000 miles or less) can extend engine life if you ride in aggressive off-road conditions or extreme environments. The first change should be done by 600 miles.
  • Oil Quantity: The recommended capacity is 1.6 quarts of oil. Do not overfill.
  • Oil and Filter Compatibility: Always use JASO MA-rated oil for wet clutch compatibility. Filters such as the Hiflofiltro HF112 are equivalent to OEM.
  • Skid Plate Note: If you have an aftermarket skid plate, you may need to fully remove it as oil can become trapped in side wings during a change.
  • Magnetic Drain Plug: Upgrading to a magnetic drain plug can help track engine wear by collecting metal particles, though it’s not required by Honda.
  • Crush Washer and Gasket: Though riders sometimes reuse these, replacing both at each change is recommended to avoid leaks and maintain positive engine health.
  • Correct Reassembly: When reassembling the filter cover, ensure the gasket and spring are positioned correctly—incorrect assembly can lead to leaks or poor oil pressure.

Disposal and Safety

  • Always dispose of used oil and filters at a recycling center or automotive store that handles hazardous waste.
  • Wear gloves and safety glasses to protect yourself from hot oil and contaminants.

Regular oil changes are key for engine longevity and optimal riding. Keeping your 2019 Honda CRF250L Rally ABS filled with quality oil and a fresh filter ensures top performance on every MotoSport adventure.
