Charging Problems and running issues

I have a 1980 kz1000 frame with a 197? 900cc motor. Dyna S ignition, k&n filters, 28mm stock carbs.

The bike was running when parked but due to the shifter fork breaking it sat for three years.

The forks have been replaced and motor back into bike and I have been trying to get it running.

The carbs have been cleaned out floats working (not over flowing and leaking gas). Slides moving

up and down easily. They have been bench sync'd. The voltage at the battery post reads between

11.5-12.9. The wiring has been hacked on and have a black wire and white wire coming from the

rectifier not connected to anything, where do those go? It runs for awhile then will start

missing at idle and then die and wont start with out being on a charger. Any ideas on charging

system would help!!



Another thing is when I finally thought I had it running good enough to ride it would just spit

and spudder through any throttle position. Any ideas? Ive ran out? Dont know much about

motorcycles but very mechanically inclined.
