Tools & Supplies Needed

  • Engine oil: Yamalube 10W-40 or a high-quality equivalent (see your manual for exact specification and capacity)
  • Oil filter: OEM Yamaha or equivalent aftermarket for WR250F 2016
  • Drain pan
  • Socket set: 8mm, 10mm, 12mm sockets and ratchet
  • Oil filter wrench
  • Funnel
  • Clean rags or shop towels
  • Torque wrench
  • New crush washers (recommended for drain bolts)
  • Safety gloves
  • Owner's manual (for reference)

Step-by-Step Oil Change Instructions

  1. Warm Up the Bike
    Start the engine and let it run for 3 to 5 minutes to allow the oil to warm up and thin. This ensures effective draining. Turn the bike off and wait about five minutes for oil to settle in the sump.
  2. Prepare the Work Area
    Place a drain pan under the bike. Remove the skid plate (if installed) and set it aside. Wipe around the drain bolt and oil filter cover to prevent debris from entering the engine.
  3. Remove the Oil Filler Cap
    Unscrew the oil filler cap on the right side of the engine. This enables the oil to drain more quickly.
  4. Drain the Engine Oil
    • Locate the main drain bolt on the right side of the engine case.
    • Use a 12mm socket to remove the bolt. Allow the oil to completely drain into the pan.
    • Depending on frame type: On the 2016 aluminum frame WR250F, find and remove the oil reservoir drain bolt (generally under the right frame near the down tube). If oil flow slows, unscrew the oil tank breather bolt at the top of the reservoir.
  5. Remove and Inspect Oil Filter
    • Use an 8mm socket to remove the oil filter cover. Carefully pull out the oil filter element.
    • Inspect the filter for excessive debris, which may indicate internal engine wear.
    • Clean the oil filter cover and inside the housing with a clean rag.
  6. Check and Clean Oil Strainer (Screen)
    • On the 2016 WR250F, an oil strainer (screen) is located in the oil tank. Remove this with the appropriate socket (often 12mm), clean it with solvent, and allow it to dry before reinstalling.
  7. Replace the Oil Filter
    • Install a new oil filter, ensuring it's seated correctly and oriented as shown in the owner's manual.
    • Reattach the oil filter cover. Tighten bolts evenly to manufacturer's specification (check your manual for torque values).
  8. Reinstall Drain Bolts
    • Fit new crush washers on all drain bolts if available.
    • Reinstall and torque the drain bolt(s) to spec to avoid leaks or stripped threads.
    • Refit the oil strainer bolt and oil tank breather bolt if removed.
  9. Fill with Fresh Oil
    • Using a funnel, pour recommended oil into the filler opening. The 2016 WR250F typically takes ~1.1 liters (1.2 US qt) with filter change—always double-check in your manual for exact volume.
    • Replace the filler cap.
  10. Start the Engine and Check for Leaks
    • Start the bike and let it idle for a few minutes. Shut off the engine, then check for leaks at all drain and filter locations.
    • After waiting a couple of minutes, check oil level. Add oil if necessary to bring the level to the upper line on the sight glass or stick.
  11. Reinstall Skid Plate
    • Reattach the skid plate (if removed), and ensure all bolts are properly tightened.
  12. Dispose of Old Oil Responsibly
    • Bring used oil and filters to a recycling center or automotive parts store equipped for hazardous waste disposal.

Model-Specific Call-Outs for the 2016 Yamaha WR250F

  • Reservoir Location: The 2016 WR250F uses a separate oil reservoir in the aluminum frame. Two drain bolts must be removed: one on the engine case, the other under the frame reservoir. Don't miss the frame drain during your service.
  • Oil Strainer: This model includes an oil strainer housed in the oil reservoir. Be sure to remove, inspect, and clean the strainer at regular intervals or whenever doing a full oil change. A clogged strainer reduces oil flow and could damage your engine.
  • Oil Capacity: The oil capacity varies depending on whether you replace the oil filter and strainer. After a filter change, expect to use about 1.1 liters (1.2 US qt). Overfilling can cause foaming, so check the manual for proper levels.
  • Torque Specs: Exceeding torque can strip aluminum threads. Always follow the precise torque specifications in your owner's manual for both drain and cover bolts.
  • Skid Plate Removal: The WR250F's stock skid plate often must be removed for complete access to the reservoir drain bolt. Take care not to lose hardware.

Tips and Reminders

  • Use only motorcycle-specific engine oil—the clutch and transmission share the oil bath.
  • Never start or run the engine without oil.
  • Keep a log of oil changes for maintenance tracking and warranty purposes.

Following these steps ensures your 2016 Yamaha WR250F remains in peak condition for every ride. For all your WR250F parts and supplies, trust MotoSport.com—your dirt bike's best friend on and off the trail.
