Specifications – Owner Call-Outs

  • Oil capacity: 1.2 liters without filter, 1.3 liters with filter replacement
  • Change interval: Every 1,000 km or approximately every 7.5 hours of use. Inspect before every race, change after every 5 races or as required by your riding regimen.

  • Special note: Always inspect oil strainer every 2-3 oil changes—debris is rare, but critical to check periodically.

Step-by-Step Instructions

  1. Warm Up the Engine
    Start the engine and let it idle for several minutes. This warms the oil, allowing it to drain more thoroughly. Turn off the engine and wait at least 5 minutes to let oil settle before draining.
    Tip: Place the bike on a stand for level draining.
  2. Drain the Oil
    Use a 12mm socket or wrench to remove the drain bolt located on the bottom of the crankcase. Position your drain pan underneath before removing the bolt to catch all used oil.
    (Replace the crush washer on the drain bolt if needed; this is a common leak point.)
  3. Remove and Replace the Oil Filter
    With the oil almost finished draining, use your oil filter wrench to remove the oil filter.
    • Carefully wipe the filter mounting surface with a clean rag.
    • Lubricate the gasket of your new oil filter with a bit of fresh oil and install. Tighten by hand and then give it a gentle snug with pliers—do not overtighten (the cap is plastic and can crack easily) .
  4. Check/Inspect the Oil Strainer (Optional)
    The oil strainer should be checked every 2-3 oil changes or if there are any signs of debris in the oil . Remove the strainer, clean it thoroughly, and reinstall it.
  5. Reinstall the Oil Drain Bolt
    Thoroughly clean the drain bolt and install a new crush washer if you have one. Torque the bolt to Yamaha specification—do not overtighten, as the threads can strip.
  6. Add Fresh Oil
    Using a funnel, add 1.3 liters of 10W-40 motorcycle oil (if you changed the filter) or 1.2 liters (if you did not) back into the engine. Use a measuring cup for precise volume.
    Do not overfill. Check level regularly during this process.
  7. Check Oil Level
    After filling, replace the oil cap and dipstick. Start the engine and let it idle for 2-3 minutes, then turn it off and let it sit for one minute. Check the level via the sight glass or dipstick; add oil if necessary to reach the correct mark .
  8. Dispose of Old Oil and Filter Responsibly
    Take all used oil and filters to a certified recycling or disposal site in compliance with local laws.
  9. Reset Your Maintenance Log or Yamaha Power Tuner App
    Log the oil change in your maintenance record or reset the interval in the Yamaha Power Tuner app, if used .
