That doesn't look stock to me, is it?
In stock form, Red is 12v from the fuse and then goes to the key switch. Yellow/black is 12v from a CDI transistor leading to one side of the solenoid coil. Blue/black is the other side of the solenoid coil and goes to the start button, which pulls the blue/black to ground when pushed.
It is nearly impossible to tell you what to do when your wiring is butchered and non-stock.
The run/stop switch is supposed to be the ONLY 12V provided to the CDI via red/black wire... sounds like not in your case.
IMO, if you can't figure out what is necessary to make the quad start, run and stop, you better carefully return it to original wiring connections as defined in the manual.
All you MUST have are power to the CDI from the run/start switch, black CDI ground, transistor switched power from CDI to solenoid, wire from solenoid to start button and the neutral or clutch switch wire grounded so the CDI will allow a start - and all the stator wires and orange to coil + coil ground.
