And for a little more security you could check this
http://www.valkyrieforum.com/bbs/index.php/topic,18768.0.htmlWay down is a diagram from MarkT for installation of a push-button initiator for the valve. If you don't push the button after turning the key (or someone tries to steal the bike without knowledge of this button) the valve doesn't open and the bike dies of fuel starvation within about a mile.
It also shows how to add an LED to show you that the valve is powered on...

I did something similar on my bike, but rather than use a push button I used a keyed switch that I bought off eBay.
