So...Why couldn't you take the key assembly from a pocket rocket and use that as the kill(on/off)switch?
 
You could easily replace the kill switch with a keyed switch.

That doesn't change the fact that more often than not, when the white wire is in the circuit, your kill switch fails - regardless of if it was on a keyed switch or a push button kill switch.
 
i made a neat little keyed switch from some clear acrylic, a pocket rocket switch i had lying around, a rubber dust cover from a bearing cuz the nut for the switch shattered, which i press fit onto the switch to hold it on, and soldered it all together and it looks awesome , i might try to get some pics
 
My kill switch is wired like everyone says, but it STILL won't work. Instead of a black and white wire coming from my switch, I have a red/yellow wire and a green wire. My bike is wired like this

Blue engine - Blue CDI
Black Engine - Black CDI

Red/Yellow Killswitch - Blue CDI
Green Killswitch - Grounded to frame


What could possibly be wrong here?
 
But the green wire has a metal loop on it, isn't that supposed to be grounded to the frame?
 
It's not necessary at all.

That is how the kit instructions tell you do, and you "can", but it's a more secure connection to ground it via the black wire.

As well, this means you don't have to strip paint from your bike. Give it a shot, you'll see.

Lastly - where is your white wire? If it's not capped off, cap it off.
 
Thanks for the instruction, I'll let you know how it goes when I get the chance
 
blue/green to blue/green (pos)

black to black (neg)

white capped off, or used for single 6V/3W bulb (pos)

insulate the connections from ground & each other

splice killswitch into blue/green connection EDIT:see link in post #5
(with a 2-wire switch, one wire into blue/green splice, other side to ground/frame)

kindly post this link in reply to any questions about basic wiring.
on my chines 2 stroke 70cc engine there is not a green wire

The kill switch wires can be switched, all they do is complete a circuit.

:::::WIRING GUIDE :::::

Okay, first we will take note of our wires.

NOTE: Different brands tend to use different colors for some wires, so use the process of elimination to determine what color a wire is if it is not stated here.

*Kill Switch Wires : Green Wire & Red/Yellow Wire.
*Engine Wires : Blue Wire & Black Wire & White Wire.
*CDI Wires: Blue Wire & Black Wire.
*Other Stuff: Wire Cap

Now that you know what wires you have, it's time to connect them.

1. Engine's Blue Wire to CDI's Blue Wire.
2. Engine's Black Wire to CDI's Black Wire.
3. Kill Switch's Green Wire to Engine's & CDI's Black Wire.
4. Kill Switch's Red/Yellow Wire to Engine's & CDI's Blue Wire.
5. Engine's White Wire to Wire Cap.
