Methanol tap, has to close automatically if I fall and control from the handlebars... Tall order, drawn a few designs, it got simpler and simpler as it went!!! The basis is a S/S Swagelok 3/8th valve
Result:
Spring return, cable operated from a twin cable throttle mounted on the left hand side clip-on. The cable will pass through it and the lanyard underneath to hold it open. I also plan to put a micro switch on the back of the tap to kill the ignition when the valve closes.
See you all,

Patrick, I don't want to put down your brilliant tap !!!
On the contrary; it's a extraordinarily well made nifty little contraption
BUT
I tried , or rather the guy who helped me in the beginning of my build,
tried to make something similar
...with internals based on an existing tap, just like you did
...but it never got to work well.....er....at all
What the rules actually says it that
1)...you need a positive off kill switch to stop a running machine,
operated without removing hands from handlebar
2)...you must have a tether-type / lanyard kill switch
3)...running 'fuel' ; you must have a fuel shut-off
operated without removing hands from handlebar
...so instead of investing in a 60£ tap, do a lot of machining, run cables
and buy, and install, a, twin cable throttle AND a micro-switch
AND buy, and install, a handle-bar mounted switch for the ignition
the whole thing can be solved with a 44.24£
12 volt fuel solenoid-valve from
HEREand a switch on the handle-bar that
kills engine AND fuel in one go,
like I ended up doing
( + the lanyard thingy that you're gonna need under all circumstances )
