10 Things You’ll REGRET Not Doing to Your Motorcycle

The video script introduces a motorcycle maintenance tutorial sponsored by Carvana. The host, Jeremiah, emphasizes the importance of various checks and maintenance tasks to prevent motorcycle failure. He discusses the necessity of changing engine oil to assess the bike's condition and mentions the use of a shop manual for specific maintenance details. The script also covers the significance of motorcycle oil serving multiple functions and the process of changing oil and filter, including pre-filling the filter with oil for immediate lubrication upon startup.

This section of the script focuses on the critical nature of brake fluid maintenance. It explains the risks associated with old, contaminated brake fluid, such as the formation of vapor under high temperatures leading to a 'vapor lock' and potential brake failure. The host demonstrates the process of changing the brake fluid, including bleeding the brakes to remove old fluid and air from the system. The choice of high-quality DOT 4 brake fluid, specifically RBF 660, is highlighted, along with warnings against mixing different types of brake fluids.

The script proceeds with a discussion on the degradation of coolant and the importance of its timely replacement to prevent damage to the engine's seals and hoses. The host describes the process of draining the old coolant and replacing it with a mixture of distilled water and a coolant additive to inhibit corrosion and lubricate the cooling system. Additionally, the issue of poor-quality gasoline, particularly its high ethanol content, is addressed. The host advocates for the removal of old gasoline and its replacement with fresh fuel to prevent engine damage from oxidized, varnished fuel.

The fourth paragraph delves into the importance of air intake and spark plug maintenance. The host stresses the need to replace the air filter for better engine performance and as an indicator of previous maintenance practices. The process of checking and replacing spark plugs is detailed, including the significance of the correct spark plug gap and the advantages of using iridium-tipped spark plugs for their longevity and better spark quality.

This section highlights the importance of tire and chain maintenance for a motorcycle's road performance. The host explains how to check tire manufacturing dates and tread depth, emphasizing the need to replace tires every five years regardless of usage. The correct tire pressure is discussed, and the host demonstrates how to inspect and replace brake pads. The script also covers the process of cleaning, lubricating, and adjusting motorcycle chains to prevent premature wear and ensure optimal performance.

The final paragraph provides a comprehensive guide on lubricating various parts of the motorcycle, such as brake pins, axles, throttle and clutch cables, to ensure smooth operation and prevent sticking or seizing. The host also covers the process of adjusting chain tension and emphasizes the importance of starting with a fresh baseline for maintenance records, including mileage and engine hours, to track the bike's health over time.
