Please help!! This thing is driving me crazy!

I bought a Roketa 110 atv from a buddy at work. It hasn't run since last spring.. He gave me a brand new battery(which I filled with acid and charged before install)

With the key on, brake pulled (brake lights come one) and push the start button, the solenoid clicks. Logically I tried to short the two posts on top.. No sparks.
When jumpering from positive lead on battery to the post on the solenoid that goes to the starter, it turns over and tries to fire.. But does not.
Same thing happens when jumpering from positive battery terminal straight to the lead on the starter.
I replaced the solenoid with a new one.. Same deal.
The kill switch near the rear of the atv is completely disconnected. The red and black wire loom and the green and yellow wire loom are just hanging.

Am I looking at a wiring issue or something else? Any help is appreciated!!!
