Old school, back in the day bike thieves would carry a pair of HT leads for just such occasions
fuck me, did no-one see the link I posted?
oh Yeh. Lol
Wouldn’t it be simpler to fit the number plates with Velcro so you can remove it, that way you don’t need to pay for petrol 
Lol, now there’s an idea
basic waterproof google battery isolator switch
this HTML class. Value is http://www.tcschandl
Link wont post all i get is above
Jay its broken again
What about a transponder. i think that the name for it, a device that has to be local to the bike for it to start. You carry it in your jacket, and if it is out of range, the bike cuts out. If this happened at a petrol station, the scrote may even fall off the bike after 10 yards, then you could run over to him up, lifting him to his feet via his neck or an ear.
Or how about having a hand grenade on the bike, on an elasticated 25 yard wire attached from the pin to your jeans, so that if the bike is ridden off, after 25 yards it explodes. For this, you should mount the grenade under the seat, by the tank.
I think the riot was just locked up. No ignition per se just a switch. Joby
If you’re referring to my bike, no mutha-phucka would wanna touch it with a disinfected stick!
With regard fitting relays etc to the battery, mine dont got a battery! 
I got a secret switch
It is hidden away very descretely and is too small to notice if you don’t know what to look for, It fits on the live going to the coil and earth of the battery, when switched on there is no power going to the Coil so no Spark is produced at the HT lead, Therefore it can’t just be fired up and rode off.
But with your information it gives a clue of how to bypass it …dont give any information is the best idea !
