The primary reason for shutting off the fuel is safety. On a motorcycle the fuel tank is directly above the engine. If fuel were to leak it would drip directly on the hot engine. This along with the fact that most motorcycles use a rubber supply hose that is exposed to the engine heat and the resulting decomposition.

Is there any need to turn off the fuel on my bike when not in use?
Yep, It is advisable to turn off Fuel when you are parking your bike for longtime as most of the motorcycles fuel ⛽ tank is higher than the carburetor which makes the continuous flow of fuel to carburetor to from fuel tank when if carburetor failed to close the valve gas would continue to trickle into carburetor which ...
Which way is off on a Petcock?
There's no need to turn it off. It's vacuum controlled as you may know so unless the engine is running, the petcock is always off. If it leaks with the vacuum hose pulled, you know it needs a rebuild/replaced. Note: some gas always spills out of the large lines going to the carbs when you pull those from the petcock.
How does the fuel Petcock work?
It uses engine vacuum createdwhen the engine is running to pull back a small piston that allows the fuel to flow. When the engine shuts off, the vacuum is removed and the fuel shuts off. ON is the position for normal operation and the position you return to after refueling the bike.
What does a fuel shut off valve do?
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.
In which gear bike consumes more fuel?
Also, it should be kept in mind that the higher the speed of your vehicle, the higher will be the fuel consumption. A 150CC motorcycle can easily go up to 55-60 kmph range on third-gear. Going beyond the said speed will put stress on your engine and will lead to greater fuel loss.
Which gear consumes more fuel in car?
Shift to the highest possible gear without the engine knocking. A car consumes more fuel in lower gears when accelerating. If the engine's not pulling, shift down instead of pressing the throttle.
How do I know if my Petcock is bad?
Re: How to tell if a petcock is bad? If the bike runs on RES and PRI but has issues running in ON,then the petcock is bad. If you disassemble the petcock,you will more than likely damage the internal diaphragm.
Can you bypass a Petcock?
Since the F2 doesn't have a fuel pump or anything else between the tank and carbs, you really should have something that will shut off the fuel when the engine stops. That's what the vacuum operated petcock does. If you bypass it, you risk completely filling the engine with gas if your floats stick.
How do you clean a clogged Petcock?
Using something pointy, gentle pry the four holed rubber grommet out of the petcock. Wash the petcock out with clean gasoline. Flush the gas tank out with clean gasoline. If it's all rusty inside, acid etch it and seal it with Kreem or POR-15.
Why is it called a Petcock?
The "pet" part seems to be rooted in an old sense of "pet" meaning "small," possibly related to our modern "petty," in turn harking back to the French "petit" (small), which all makes sense since a "petcock" is, as we noted, a small faucet.
Why is my fuel Petcock leaking?
At worst, fuel fills the cylinder, eliminates compression and prevents the piston from moving. Once the petcock is "off" you'll notice gas leaking out of the face of the petcock. That's when you know it's the petcock and not anything else associated with the fuel system.
