How do you turn off a petcock?
Counter clockwise is “OFF”. Clockwise is “RESERVE”. Check it by turning to the off position and pull off the gas line. If it doesn’t flow then you have it.
Can you hose clamp a fuel line?
They are used on fuel injection hoses. Just take a piece of hose in and get the right size. You could use regular gear clamps but they tend to pinch the hose and then you get a leak.
Can you bypass vacuum 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 remove the fuel lines from a petcock?
Just take a tiny screwdriver and carefully probe around the line to free it up then a regular screwdriver to push the line off while you tug with your other hand. Have a rag underneath when it lets go to catch all the residual fuel left in the line.
Why does the fuel petcock valve need to be turned?
More modern motorcycles have changed some of this in a few ways: the fuel petcock could be vacuum operated, closing with the engine off. the fuel tank could be lower than the carbs, making a fuel pump necessary.
How does the fuel shut off valve work?
The fuel shut off has three positions run,reserve and off. The difference between run and reserve is the length of the fuel delivery tube that brings fuel out of the tank. The “normal” run tube rises about 35mm from the bottom of the tank. This means that when it stops delivering fuel approx 35mm of fuel left in the tank.
Can you use crimp clamps on a vacuum line?
These crimp clamps are only intended to be for one time usage, once cut they cannot be removed again. They can be found on a variety of applications such as vacuum lines, coolant lines, fuel lines, hydraulic lines, washer fluid lines, etc. Thank you to all those who watch my videos and support my content.
What happens if the fuel tank leaks on a motorcycle?
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. On an automobile the fuel is usually isolated from the heat and transfered from the tank to the engine via a steel line.
Why is the fuel petcock valve turned off on a motorcycle?
fuel injection has eliminated the use of carburetors and floats to control fuel flow. 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.
