HuaSheng 142F on/off switch removal

[azbill]

I recently got a brand new, in the box, 142F really cheap ($80)on craigslist
I am planning on keeping it as a back-up, in case mine ever dies (13.5k miles so far)

it has the on/off switch,,,
my original engine came with 2 wires to hook to a kill switch
this engine has only one wire running to the switch, which looks to be grounded to the engine

my question is,,,do I need to hook a grounded wire to change to a kill switch ?,
and if so, where should I run it from ???

If you mount it to the bars, it will ground that way. (with the correct switch. I use $12 Honda ones but is over kill, snork))
I use this method with the HFs using the pos wire for the low oil sensor/shut off.

I like this method as using only one wire is a little neater.

Score, 80 bucks. Suweet.

My HS is the same way, just a single wire. I removed the stock switch and replaced it with one more accessible. I also have a second, hidden killswitch that I won't go into.

Here's a couple pics of my main switch and how it's routed. It's a very basic setup:

take the black wire its the only wire comeing out of the coil pack other than the spark plug wire that up to one wire of the switch then take the other wire of the switch you are useing and wire it up to ground simple as that

the green wire is useless just take it off youll notice that it just grounds the coil to the motor when the coil touches the motor anyway..
