This is simple cheap tech tip for installing an anti theft switch to help protect your lovely XS/XJ motorcycle from being stolen.
Many of you probably are a little paranoid at the thought of loosing your precious badazz 1/4 mile vintage japanese muscle bike, and if you are not, than you should be. Maybe I shouldn't mention for prying eyes to see that anyone can look at your lock and have a key made for it, then one day you come out of your home and see the empty spot where your bike used to sit. Well there is a remedy for it that many bikers have figured out.
Things you will need,
1. A 2 pole toggle switch.
2. Wire strippers.
3. A few simple connectors.
As far as I know, every XS/XJ is equipped with an Emergency Stop Switch, otherwise known as a tilt switch. The Emergency Stop Switch is a little safety device designed to make sure the bike shuts off if leaned over 60 degrees, like say during a crash, or maybe when you get clumsy and drop it at a stop sign. The switch simply kills coil power via the Ignitor Unit.
If you look at your ignitor unit, there is a Black wire with a White stripe that goes to the Emergency Stop Switch. This is a 6V wire that when grounded kills the coil signals stopping spark.
All you have to do, is splice the B/W wire, then attach a new wire length from it, to the first pole on the toggle switch. If you want to keep the function of the Emergency Stop Switch (recommended), then make sure the B/W wire is still able to make a connection with the ESS. Then you attach another wire to the second pole of the Toggle Switch and attach it to a ground source on the frame or negative battery terminal.
To test it, flip the switch to on, making it ground the B/W circuit wire, and try to start it. You should have no spark at this point. Make sure you hide the switch in an inconspicuous area out of site that only you know about. The best place would be somewhere that can't be seen where you can only reach it with your finger.
This switch is safe for your bike and will not damage your circuit's, because the Emergency Stop Switch actually works by grounding the B/W wire.
This method may not stop a professional bike thief because they more than likely know this trick, but it will stop the ignorant common thief moron that wants to be cool and steel your bike. Even hot wiring the ignition wouldn't start your bike if the switch is on. It's just a little extra insurance.

you'll be wishing you'd installed one of these babies! 
Maybe you'll even hear the noise in your shop, and catch the punk in the act.
