I've just purchased a new Raptor petcock to replace the stock petcock on my 2006 S40. After reading several posts  I am under the impression that I need to turn the fuel valve to the off position after shutting it down and parking it.  Is this every time or only if I'm letting the bike sit for an extended period of time without riding it?  Clarification please.
Thanks

Got it, thanks.

As a safety precaution and not to create any issues, I’ll put it in the off position when I’m not riding. I’d rather be safe than sorry.
My parents raised only one idiot, that’s my older brother. 😊

I do the same things......the STOP sign down the street gets me to my driveway before the sputtering commences, and I have a downhill driveway.

We have reformulated E10 fuel.....I don't like that stuff corroding things in my float bowl as the bike is waiting for the next ride.

If I run the engine out of fuel, there is very little crappy E10 fuel in the float bowl to promote the corrosion or dissolve the rubber parts.  

New equipment is shipped with empty float bowls - and I can't imagine the mile ride to my house as the float bowl drains is harder on the float than being shipped from Japan or China.  All float assemblies have "stops" built in that prevent the float from dropping too far - the range of motion is limited and prevents any potential damage.

I have never had any problems with clogged up carbs or getting the bike started once I began to run the float bowls dry as I arrive home.

I do live on a paved road.......and how much "forceful slamming" do you believe 1/2 oz of fuel can impose?     

Batman:

My neighbor brought over his CR450 Honda, as fuel was pouring out the float bowl.  I took the carb apart, and discovered the rubber tip of the float valve had been pushed crooked by the white blossom of corrosion the ethanol caused.  Your fuel in New York is not the crap we get in Northern KY.....in a very short time this fuel will turn aluminum white and fuzzy, and turn rubber parts into taffy. (The problems begin when the fuel portion evaporates and leaves behind a high concentration of ethanol).

Your world and where you ride are obviously different from mine.  My use of the Raptor petcock works for me.....and I am going to continue to shut it off at the intersection down the road.

You might get the Willies on your local roads - mine are far more forgiving.  I shut off the fuel at same intersection (my visual cue to turn off the petcock at the end of my ride), and it begins to sputter as I reach my drive every time.....same routine for the past 6 years.  And most times I never see a car for that last mile, as I live in a rural area where traffic flow is low and speeds are slow.  "Oncoming traffic".....you will likely have to wait 20 or 30 minutes before any of it comes along.

Here is a photo that shows the road I live on - my driveway is on the left side, just beyond the tree line.

 

Well now I feel bad for you guys , I guess you have to do what works for you , thankfully I don't ,but Dave did mention they where getting rid of Reformulated fuel ( what ever that is!)  So maybe you'll have better luck in the future.
