Should you turn the petcock off?
No, there is no legal requirement that you should turn the petcock to “OFF” when you shut your bike down at the end of your ride. However, it is a good practice, especially if you own an older motorcycle (1990s vintage or earlier), before gravity-fed carburetors were largely replaced with fuel injection systems.
What is the purpose of a fuel shut off valve?
Not only does shutting off the fuel valve prevent the engine from flooding while being transported, it prevents flooding because of contamination in the float valve, and extends the life of the float valve by decreasing pressure on it.
What is the purpose of petcock?
A petcock is a small shut-off valve used to control the flow of liquid or gas. Historically, petcocks were threaded valves controlled by a butterfly handle; modern petcocks are typically ball valves.
What is reserve on petcock?
The reserve fuel switch, also called fuel petcock valve, or simply fuel valve, is used to control the fuel flow from the tank to the engine.
How does fuel shut off solenoid work?
How does a engine stop solenoid work? Before the engine starts, the solenoid is energized, which opens the flow of fuel to the engine. The engine then cranks and should start. When you stop the engine, the power to the stop solenoid is removed, which closes the fuel line and the engine then stops.
What is the position of fuel valve?
Reserve Fuel Switch (Fuel Valve) The reserve fuel switch, also called fuel valve, is a three way valve typically located on the left side of the motorcycle directly under the fuel tank and near the carburetor.
How does reserve work on petcock?
When the petcock is set to “Reserve”, the “Reserve” tube is selected. When the petcock is set to “Off”, no tubes are selected, meaning no fuel sent to carburetors. When you set the petcock to “On” and start riding the fuel from the tank will be used until it reaches the top of the “Main” tube.
Do you need fuel petcock?
A petcock can serve as a bit of a theft deterrent, but shouldn’t be relied on for that purpose. When in the ON position, fuel is freely drawn from the tank to the carburetor. This allows the engine to operate. If you find the engine is hard to start, check that the fuel is turned on.
