Turning off Gas

I agree that the point is valid. It's just dated.

And like you said, if people are riding around with faulty fuel control valves, then they have bigger problems than simply remembering to turn the petcock to "off".

The OFF position is a routine safety factor that was taught way back when. My first bike had the OFF position. Even well into the 80's there were dual purpose bikes and off road bikes with an actual off position. I think the safety lesson is just left in there to cover all the bases for the unwary.

If I remember correctly, the Honda Rebel I used in my MSF class 4 years ago had an OFF position, not a vacuum operated petcock.

On the 85 to 90 Kawasaki 454's,they used to different petcocks,both vacuum operated.The first petcock had "off,on,res".The second one had "pri,on,res".I like the second style better,as you can prime the carbs without turning the bike over.With the first style you need the bike turning over to get vacuum to fill the carbs.On the up side the first one has a positive "off" position.My bike has the second style,and when been stored,I remove the fuel line from the carb and plug it.I don't rely on the petcock alone to hold back the pressure of a full tank of fuel.(I always fill tank before storage).

When you remove the fuel line to plug it, dont fuel go all over the place and spill ?

No...... Read the whole post You'll see that the "run" position takes engine vacuum to open the valve & let fuel flow. On the other hand, if you removed the pipe in "prime", then, certainly, fuel would flood out.

Not on a vacuum operated petcock.The petcock needs vacuum from the engine turning over to open and let fuel flow.If you are on "pri" position,no vacuum is needed and fuel can flow.
