The elcrical system explained, ... simply
 As soon as you turn you turn on the ignition key, the battery gives the power you need, as soon as the engine is started, the generator does.
 You hit the electric start, the battery send power through  to the solenoid, the solenoid clicks into position and allows the power needed turn over the starter engine get to the starter motor.
 The starter motor turns the engine, which turns over the generator.
 The generator sends power through the reg rec, the regulator stops too much power getting through to other parts of the system, the rectifier takes any excess and dumps it (usually as heat)
 Then to the main fuse  which goes to the CDI box or points and condenser (see below) as well as charging your battery. It also sends power to  the other fuses (if you have any) to run your lights, horn and other ancillaries
 The points & condenser makes sure that the power to the spark is sent at the right time, timing that spark is essential.. The timing is done here  the position of the points is essential, as is the gap and condition of the points.
 The points or CDI box sends that power to the coils at the right time using the pick ups.
 The coils then change the 12v electricity and change it to a much higher voltage releasing all the power for just a split second when it's sent it through the HT lead and into your spark plug where it should spark between the electrodes at the plug in your combustion chamber.
This is just a general guide.
