Here's why:
* Owner's Manual is Key: The most accurate and reliable information will be found in your motorcycle's owner's manual. This manual will have the exact fuel-oil ratio recommended by the manufacturer for your specific model year.
* Varying Recommendations: Fuel-oil ratios can change depending on the model year, engine type, and environmental factors. What's suitable for one motorcycle might not be right for another.
* Engine Damage Risk: Using an incorrect fuel-oil ratio can lead to engine damage.
Where to Find the Right Ratio:
1. Owner's Manual: The most important source! If you don't have it, you can often find a digital copy online (check Yamaha's website or motorcycle forums).
2. Yamaha Dealer or Mechanic: They can help you find the correct information and can also provide expert advice on fuel-oil ratios for your specific model.
Remember: Always follow the manufacturer's recommendations for fuel-oil ratios. This will ensure the best performance and longevity of your engine.
