    Here is a pic of diagram.

    In China green is ground instead of black.

    Flameout is Kill switch.

    You can ignore the electric start stuff.

    .

    12 volt Chinese engine project involves 2 wires from the engine- usually



    Black/red from engine can also be yellow/red in some cases is power to cdi box-

    usually goes to red/yellow in the harness-leads to CDI box

    Blue/white from engine can also be red/white in some cases and is the cdi trigger/pulse-

    One wire from the CDI box to the Coil (+), Coil (-) goes to ground.

    Black/yellow wire from cdi box harness goes to the coil + which can be black/yellow stripe or black/white stripe .

    This will get a 12 volt engine running.

    Its very simple to do, but I had a bad kill switch which made me scratch my head till I figured that out. Most times you ll have two wires left over on a china motor ( headlight coil ) and I forget what the other one was off the top of my head ( hey I dont have to think on sunday mornings ).



    Here are a couple of pictures off a 120 lifan of mine.



    I clipped ends off another harness I had for the bullet connectors so it looked better and gave me a little more wire length.





    Here are the two left over wires you will have left if you have a 5 wire setup.



    Here are two pictures of what you would have left if you have it wired correctly.





    The last open bullet connector you see is for your kill switch.



    Good luck , hope that helps.

    Lack of preparation on your part , does not create a sense of urgency on my part "



    I just like to blow stuff up....



    We drag race/road race. My signatures are based totally on our experiences in those two areas. We DO NOT mx race our bike. So my opinions/theories may be totally different then what you need to hit a 50 ft jump, compared to what we need to hit 100 mph.

    okay i put a ground in from my motor to stator but all the grounds are connected now i need to figure out where the blk/white wire needs to go its between my cdi and rectifier theres a wire that connects them then it branches off with a ground im pretty shure it goes to my kill so if it isnt connected it should run correct? otherwise ima have to go get my kill switch from my frineds garage...
