Understanding the Pitcock’s Function
The pitcock, also known as the fuel valve or petcock, is a crucial component in any motorcycle’s fuel system. Its primary function is to regulate the flow of fuel from the fuel tank to the engine. It typically has multiple positions, including “On,” “Off,” “Reserve,” and sometimes a “Primed” or “Start” position.
The “On” position allows fuel to flow freely from the tank to the engine, providing a constant supply for normal riding. The “Off” position completely shuts off fuel flow, preventing fuel from entering the engine. The “Reserve” position is typically used when the fuel level in the tank is low, allowing access to the remaining fuel in the reserve portion of the tank.
Some pitcocks also include a “Primed” or “Start” position. This position opens a valve that allows fuel to flow directly into the carburetor or fuel injector, assisting in starting the engine when it is cold or has been sitting for an extended period.
To understand how the pitcock works, it’s essential to know about the different vacuum-operated and manual pitcocks:
Additional Considerations
