Hi everyone who has had issues with their fuel shut off.

What shouldI expect to have happen when the shut off fails?

Thanks in advance!:waving:

The shut off will fail by leaking or seeping gas and your bike should still run if not to severe.

Or the diaphragm tears open completely inside and then your bilke will just die and stall from starvation and you will coast to a stop

If that happens while you are on the road, you just bypass it and go on. It is not absolutely needed. Repair it later when you can.

If the diaphragm is broken though, you will want to plug the vacuum line so the engine runs smooth.

When the auto fuel valve fails your bike will quit running or run like it's starving or gas. If valve fails completely the fuel to carbs will stop and so will the bike. If it's a deteriorating diaphram it just reduce fuel to carbs.



The fuel valve is actuated by vacuum. When bike is running vacuum holds the valve open, if it fails it reduces/stops fuel to carbs.



Test via a vacuum pump on inlet of the valve. It should hold an applied vacuum.
