Shop parts for a 1989 Honda XR250R Dirt Bike.

Changing the oil in your 1989 Honda XR250R is a vital part of its maintenance routine and can extend your engine's lifespan while keeping performance levels high. This guide is proprietary to MotoSport.com and tailored to XR250R owners. The steps, tools, and specific precautions apply to the 1989 model, with particular callouts where needed.

Tools and Supplies Needed

  • Socket wrench set (8mm, 10mm, 12mm sockets)
  • 17mm socket or wrench
  • Oil drain pan
  • Shop rag or paper towels
  • New oil filter (highly recommended: check compatibility for 1989 XR250R, e.g., High Flow HF112)
  • Honda 4-stroke motorcycle oil (or equivalent, API SF/SG, SAE 10W-40 or 20W-50)
  • Measuring container
  • Funnel
  • Protective gloves

Preparation Steps

  • Warm up the engine for 5-10 minutes to circulate and thin the oil. This ensures more complete draining.
    Tip: Put the bike on its side stand for best draining performance.
  • Turn off the engine and let it cool briefly. Ensure the area is well-ventilated and your workspace is protected from spills.

Oil Drain Procedure

  • Locate the oil drain bolt beneath the engine – it uses a 17mm socket. Place the drain pan beneath it.
  • Carefully loosen and remove the drain bolt. Allow the oil to drain fully into the pan.
  • Model Specific Callout: The 1989 XR250R features a dry-sump system with an oil capacity of 1.3 liters (1.37 US qt) for a standard oil change, or 1.4 liters (1.48 US qt) if replacing both oil and oil filter. Avoid overfilling. Ensure you use oil recommended by Honda—API SF/SG—at 10W-40 or 20W-50 for broader temperature range.
    CAUTION: Failing to tighten the drain bolt to specification may result in leaks.
  • If equipped, change the oil filter by removing the three 8mm bolts on the oil filter cover (right side of engine). Note the order of filter and spring, and clean any debris.
  • Important: Install the oil filter with the rubber seal facing outward, toward the filter cover.
  • Reinstall the filter cover and torque the bolts evenly to avoid leaks or warping the cover.

Filling with New Oil

  • Replace and securely tighten the drain bolt (use a new washer if needed).
  • Add 1.3 liters (1.37 US qt) of fresh, high-quality motorcycle oil (or 1.4 liters if the filter was changed) via the oil filler cap/dipstick located between the tank and handlebars.
  • XR250R Funnel Callout: Filling is slightly awkward due to the filler position. Use a narrow funnel to avoid spills.
  • Insert the dipstick, but do not screw it in when checking level; rest it on the threads only.
  • Run the engine for 2-3 minutes, shut it off, and let sit for a minute. With the bike upright and level, recheck oil. Top up if needed – do not overfill, as this can cause excess crankcase pressure and leaks.
    Pro Tip: If the oil doesn't register after running, add small increments and recheck frequently.

Final Checks and Clean-Up

  • Inspect for leaks at the oil drain bolt and filter cover.
  • Dispose of old oil and filter according to local regulations (your local auto parts store may recycle used oil).
  • Document your oil change date and mileage for maintenance records.

XR250R Model-Specific Oil Change Callouts

  • Oil Change Frequency: For dirt riding, change oil every 10-20 engine hours or after every few hard rides.
  • Filter Position: On this model, always ensure the rubber seal on the oil filter faces outward. Installing the oil filter backward can cause catastrophic engine damage.
  • Draining Tip: Per the Honda/Clymer manual, after draining, “kickstart the engine a few times with the ignition off” to help expel oil from the crankcase.
    "Kickstart the kickstarter a couple times to let the oil drain out so we'll do that using the Honda manual right here by Clymer 1985 onwards."
  • Typical Oil Levels: After fill and warm-up, ensure level is at the upper mark on the dipstick, but never above.
  • Critical: Never force the oil cap/dipstick back on backward, and double-check for a positive seal—severe engine damage can result if not fitted properly.

Troubleshooting and FAQ

  • What oil should I use? Honda 4-stroke oil, API SF/SG (or higher compatible), 10W-40 or 20W-50 depending on climate.
  • How much oil is required? 1.3 liters (1.37 US qt) standard; 1.4 liters (1.48 US qt) if filter is changed.
  • Is there a special step for the dipstick? Yes. When measuring, do not screw in; insert until threads just touch filler neck for a correct reading.
  • What are the signs of overfilling? High oil level can cause frothing or leaks—always add a little at a time and check after running the engine briefly.

Always use genuine or high-quality replacement parts and oils from trusted sellers like MotoSport.com to ensure your 1989 Honda XR250R continues to perform at its best.
