How to wire Chinese 2-Stroke bicycle engine

my directions were kinda vague so this is how i did it

cdi has a black wire (ground) and a blue/green wire (pos)
engine has a black wire (ground) blue/green wire(pos) and a white wire which is positive for lights ect. 6volt
kill switch has 2 wires red and black

1. connect the blue/green wire from engine to blue/green on cdi and your red wire from the kill switch all togather.

2. connect your black wire from the engine to the black wire on the cdi and the black wire from the kill switch all together.

3. insulate all the wires.

$. the white wire is for a 6v accessory such as a light. if you do not use the white wire make sure you cap and insulate it for if it touches the frame it could short out whole system.

hope this helps

I wired my kill switch directly back to the engine. Just wrapped it around a bolt. I like yours better I didn't know it that ground would do it so thanks next time I need to rewire I'll change it.

Getting ready to wire in the kill switch.I see above it is suggested to:
1. connect the blue/green wire from engine to blue/green on cdi and your red wire from the kill switch all together.

2. connect your black wire from the engine to the black wire on the cdi and the black wire from the kill switch all together.

3. insulate all the wires.

How does this work to kill the engine when you still have an unbroken circuit
between cdi and engine?Forgive me if this is a stupid question. thanks,Ron

When you press the kill switch you complete the circuit before it goes to the cdi. there for it never gets there with the kill switch closed.

i beleive all the kill does is ground out your circuit so the engine is killed
