Shop parts for a 2000 Honda CR500 Dirt Bike.

Keeping your 2000 Honda CR500 running strong means routine maintenance, and changing the transmission/gear oil is one of the most crucial jobs you can do. Here’s everything you need to know, brought to you by MotoSport.com, with model-specific tips to make sure your legendary CR500 is ready for the next ride.

Tools and Supplies Needed

  • Socket wrench set (to remove the drain plug, usually 12mm or 13mm)
  • Measuring cup with US ounce and milliliter markings
  • Clean funnel
  • Oil drain pan
  • Shop towels or rags
  • Replacement gear oil (Pro Honda HP Transmission Oil recommended, 80W/85W type–but see brand recommendations below)
  • Replacement crush washer (optional, but recommended if your current washer looks worn)
  • Gloves (optional but recommended)

Oil Type & Capacity Specifics

  • Correct oil capacity: 23 US fluid ounces (680 mL) for a regular oil change. If you’ve split the cases and thoroughly cleaned the transmission, it takes 25 US fluid ounces (739 mL).
  • Recommended oil: Pro Honda HP Transmission Oil, but quality alternatives like Motul Transoil or Bel-Ray Gear Saver Work, too. Some owners use automatic transmission fluid (ATF), but it usually dirties faster and may need changing more often. Synthetic gear oil is preferred for smoother shifting and protection.

Step-by-Step Oil Change Instructions

  1. Warm Up the Motorcycle
    • Start the CR500 and let it run for two or three minutes. This thins out the oil so it drains easier.
    • Turn off the engine and position your bike upright on a suitable stand.
  2. Access the Drain Plug
    • Locate the oil drain plug–typically found on the bottom/right (when sitting on bike) of the crankcase.
    • Place the oil drain pan underneath.
  3. Remove the Filler Cap
    • On the right side of the engine, find the oil filler cap. Unscrew and remove it for better draining. This prevents a vacuum and allows oil to flow smoothly.
  4. Drain the Old Gear Oil
    • Use your socket wrench to loosen and completely remove the drain plug. Make sure the crush washer comes off with it.
    • Let all the oil thoroughly drain into the pan. Allow several minutes.
    • Use a rag to wipe away any old oil or debris from the drain plug and crankcase thread area.
  5. Inspect and Replace the Drain Plug
    • Inspect the drain plug for damage or wear. Replace the crush washer if it appears flattened or damaged, which helps prevent leaks.
    • Reinstall the drain plug by hand to avoid cross-threading, then tighten to manufacturer’s specifications. Do not overtighten.
  6. Add New Gear Oil
    • Insert a funnel into the filler hole.
    • Using your measuring cup, pour in exactly 23 US ounces (680 mL) of new gear oil. Do not overfill. Overfilling can cause leaks or poor clutch performance.
    • Once filled, reinstall the filler cap. Make sure it’s snug but not overtightened.
  7. Check for Leaks and Test Operation
    • Start your CR500 briefly and shut it off.
    • Examine the drain plug and filler area for leaks.
    • If there are no leaks, you’re set. Wipe away any spills.

Model-Specific Call-Outs for the 2000 Honda CR500

  • No oil filter to replace: The CR500 is a two-stroke, so you only change the gear/transmission oil. There’s no engine oil or filter like on a four-stroke.
  • Pay attention to oil color during draining: Old oil may appear milky if water intrusion has occurred–a sign your crankcase seal is leaking and should be inspected.
  • Do not use motor oil: Only use transmission/gear oil; standard motor oil is not formulated for the clutch and transmission in two-strokes.
  • If using ATF: Change much more frequently, as it dirties faster and isn't as robust as dedicated motorcycle transmission oil.
  • Check for debris: If you spot metal shavings in the old oil, investigate promptly to prevent severe engine damage.
  • Consult your owner’s manual for final torque specs, but typical drain plug torque is around 10–15 ft-lbs. Never force it.

Final Words

Changing the oil in your 2000 Honda CR500 is straightforward and requires only basic tools and about 15–30 minutes. Proper gear oil ensures your clutch works smoothly and your transmission lasts for years to come.
