So I bought a NST ATV90 for $25 because the guy who had it assumed it was blown. I cleaned out the carb and look at that it runs great.

The wiring has been hacked to death by people who don't know nothing. I want to eliminate ALL of the wiring I do not need. Here is what I want:

1) Start button
2) Switch to kill the engine

Thats it. Wiring diagrams confuse me to no end so I need a little help here. Right now all the original stuff is there except the ignition switch. I have a momentary push button switch to crank the starter.

So, what do I need to run to get it going this way? I envision a bike with minimal wiring, a CDI box, the starter relay, my start button and my kill switch lol. I do not plan on reusing any of these junky wires, I will run all new wires and connections.

 

i think you'll need the following:
keyed ignition (saves battery on/off, and secondary kill switch)
kill switch on handlebar-primary kill switch
stator output
CDI/Coil/etc....for spark
obviously like you said, solenoid and such.
you'll probably have to keep the interlock on spark in the brake switch.

 

The iginition switch is already gone, i don't want it. I want only the rocker switch to kill the engine, and my push button to start it.

I guess what is holding me up is how do i wire the kill switch? I'm guessing I need to set it up so that it grounds out the CDI box?

As for the brake switch it's already gone, that was disabled before I got the bike. Not sure why I would need to keep that since I'm going to pull all of the wire harness off the bike and run my own, only needed wiring.

 

i figured it all out
