Did you put the petcock selector on the petcock wrong? The selector is just plastic so maybe it's only partially on the petcock or something and out a notch.

I'd take it back apart and look at some pictures from the tech archives to try and be sure you didn't assemble the flaps back together wrong-side-out or anything... see that lip on the big flap in the last picture? I don't think that is on both sides... at any rate - they're definitely different on each side...  Then... don't put everything back together until is passes the vacuum test in this article: http://www.valkyrieriders.com/shoptalk/petcock.htm-Mike "no one else calls them flaps  "

Sounds like the On/Off/Res selector has been installed wrong. When the selector knob was taken off it was in the Off position, but when you put the selector back on, it was put on pointing down to the on position. This puts the selector 1/4 turn off so now all you have is off and reserve. Put the selector knob in the On position and then unscrew the selector knob and reinstall it with the selector know pointing to the Off position. You should now have all 3 selector positions.

If you are certian it is in the "off" position and it still flows gas, it needs replaced. Pull the tank and check it's functionality that way...the valk can go quite a distance on "off".
No vacuum applied, should not flow gas in any position. Vacuum applied, should not flow gas in "off" position. Vacuum applied, should flow tons of gas in "on" or "reserve".

thanks guys ,yes i did take the selector knob off to check its mounting position.the unit cam can only be turned 6, 9 , and12 o clock. just realised that i didn t check the plastic selector where it attaches to the unit, it could be worn or broken. Hubcapsc. did the rebuilt on the diaphragms and checked for function ,but i was not impressed by the seemingly low quality of the replacement kit. the bike needs major service .the broken foot kept me from doing it. now i ve no more excuses, exept the great riding weather !

Stuff made out of little flaps and springs can be maddening to work on  If the new petcock from the dealer puts you back on your Valkyrie, then that's all that really matters... If you're going to fool around with your current petcock on Sunday morning it would be interesting to hear if you can get it to pass the vacuum test in the shoptalk article and still have it leak after you reattach it to the tank... I fixed a leaky one on my buddy's new-to-him bike with a new cover set - it leaked because of this:  The previous owner tried to fix it like this:  Since the gas couldn't drip out the weep hole, it just flowed down the vacuum line to cylinder number six... get yours fixed good before you end up with hydrolock... -Mike

I experienced the same problem with mine!
Turn it to off and the gas would keep flowing. Found out when removing the tank. If I fiddle with the knob some it would turn off but it was very sensitive and the click did not guarantee that the gas was off. It was nothing to do with the vacuum side of the petcock but rather the selector side.
Solved the problem with a Pingle. Now no more worry.
That's my suggestion. Get a Pingle
