Here's why:
* Engine Design: Older Sportsters are designed to run on gasoline, not diesel or other fuels.
* Compression Ratio: The engine's compression ratio is relatively low, so it can tolerate lower octane gasoline.
* Ethanol Considerations: While modern fuel blends with ethanol are generally acceptable, you should consult your owner's manual or a trusted mechanic for specific recommendations regarding ethanol content. Some older engines may have issues with higher ethanol concentrations.
Important Notes:
* Do not use leaded gasoline: Leaded gasoline is harmful to the engine and can cause damage.
* Use high-quality fuel: Avoid using low-quality or "dirty" fuel, as it can contribute to engine problems.
* Regular maintenance: Regularly changing your oil, air filter, and spark plugs will help ensure your Sportster runs smoothly.
For the most accurate information, always consult your owner's manual or a qualified motorcycle mechanic.
