Tools and Materials Needed

  • 17mm socket or wrench (for removing the drain bolt)
  • Oil catch pan (for collecting drained oil)
  • Funnel (to help pour new oil in cleanly)
  • Clean rags (for wiping and cleaning spills)
  • Fresh engine/transmission oil (0.75 L / 0.66 Imp qt / 0.79 US qt; YAMALUBE 4 10W-40 or equivalent non-energy conserving, non-diesel oil)
  • Gloves (optional, for cleanliness and safety)

Steps to Change the Oil in a 2000 Yamaha PW80

  • Warm up the engine:–
    Start the PW80 and let it idle for a couple of minutes. Warming the oil helps it drain more fully and removes more contaminants.
  • Position the bike:–
    Ensure the PW80 is standing upright and secure, either on a center stand or flat, stable surface.
  • Prepare your tools and oil pan:–
    Place the oil catch pan directly under the oil drain bolt. Put on gloves if desired.
  • Remove the oil filler cap:–
    Take off the filler cap located on the right side of the engine. This allows air in and helps the oil drain smoothly.
  • Remove the drain plug:–
    With a 17mm socket or wrench, loosen and remove the oil drain bolt underneath the engine, allowing old oil to fully drain into the pan. Be careful, as the engine and oil may still be warm.
    Tip: Wipe the area with a rag after oil is drained to catch any drips.
  • Inspect and replace the drain plug:–
    Inspect the plug for damage or worn threads. Clean any debris from the drain plug and check its copper or aluminum sealing washer for wear. Replace the washer if needed.
  • Refit the drain bolt:–
    Thread the bolt back in by hand to ensure it isn't cross-threaded, then tighten it snugly (do not over-tighten to avoid stripping the threads). The recommended torque is 20 Nm (14 ft-lb).
  • Pour in fresh oil:–
    Insert the funnel into the filler hole and pour in 0.75 liters (or 650-750 mL) of YAMALUBE 4 (10W-40) or equivalent oil as specified. The exact capacity after an oil change is 650 mL (0.65 L) .
    Note: Overfilling can lead to engine damage. For ease, pour a little less and top off once you check the oil level.
  • Check oil level:–
    Insert the dipstick or filler cap without threading it in, then remove it to check the oil level. Adjust as needed–add oil a little at a time if under the mark.
  • Lubricate the filler cap O-ring:–
    Dab a little fresh oil onto the cap's O-ring before reinstalling to help maintain a good seal .
  • Run the engine and recheck for leaks:–
    Start the PW80 and let it idle for a minute or two. Check around the drain bolt and oil filter cap for leaks . Turn off the bike and check the oil level again, topping up if needed.
  • Dispose of oil responsibly:–
    Transfer used oil to a sealed container and take it to a recycling center or auto parts store that accepts used oil.

Model-Specific Call-Outs for 2000 Yamaha PW80

  • Compatible oil:– Use only the recommended oil (YAMALUBE 4 or SAE 10W-40). Avoid any oil labeled "CD" (diesel) or "Energy Conserving II" or higher, as these can affect clutch performance .
  • Oil quantity:– The manual and case cover often reference 0.65-0.75 L (approximately 650-750 mL). Do not overfill as typical drain-and-fill capacity is 0.65 L.
  • Drain bolt location:– The oil drain bolt is a single bolt, easily accessible underneath the engine .
  • Transmission oil is also clutch oil:– Since the PW80 uses shared oil for the transmission and clutch, never use oils with extra friction modifiers, as these can cause clutch slippage.
  • Inspect for leaks:– After running the engine, always inspect the drain bolt and surrounding area for leaks before riding.

Quick Troubleshooting & Tips

  • If oil appears milky or contaminated, investigate for signs of water ingress or gearbox issues before riding.
  • Discard old oil-soaked rags and thoroughly clean tools after each service.
  • Mark your next oil change interval (every 10-15 hours of riding or at least annually).

Following these steps and guidelines ensures your 2000 Yamaha PW80 continues to run reliably on every ride. For best results, use premium oil and OEM gaskets or washers. Trust MotoSport.com—your go-to for all Yamaha PW80 oil, filters, and maintenance supplies.
