Illustration of Motorcycle Fuel Tank Switch?
2 Answers
The motorcycle fuel tank switch is located at the lower left side of the fuel tank, connected to the carburetor via a rubber fuel hose. Generally, turning the switch handle upwards activates the reserve tank, turning it downwards activates the main tank, and turning it sideways closes the valve. The fuel tank is a container for storing fuel and can be divided into two types: open tanks and closed tanks. Motorcycles are powered by gasoline engines and are two or three-wheeled vehicles steered by handlebars. They are lightweight, flexible, fast-moving, and widely used for patrols, passenger and cargo transportation, as well as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. A motorcycle consists of five main parts: the engine, transmission system, running gear, braking system, and electrical instrumentation.
As a seasoned motorcycle repair veteran, I find fuel tank switch diagrams quite important. Typically, the switch is located at the bottom of the tank, where you can feel a small round or square valve by hand—operated by turning the handle. Common positions include ON, OFF, and RESERVE. The ON position allows fuel to flow to the engine, while OFF should be used when parked to prevent leaks. RESERVE is a backup for when fuel runs low—make sure not to confuse the positions. During routine checks, inspect if the handle is loose, check pipes for cracks, and clean periodically to prevent dust clogging. If the switch jams or leaks, it might be due to a worn O-ring and should be replaced promptly. Always operate the switch with the engine off for safety—I’ve seen novice riders mishandle it and cause fuel line issues, so diagrams should be paired with hands-on practice for reliability.
