Here's some ballpark values.
Resistance to ground:
Black Box     Wire     Colour
zero                   W     (Ground on Magneto)
474ohms       102ohms  R     (Trigger)
88Kohms       471ohms  G     (Magneto Coil)
infinity               B     (Kill button)

Spark Plug Wire: 5.35Kohms

*Do not* kick the bike over unless you have a spark plug connected and lying on
the cylinder head (and then watch out you don't ignite any gases coming out of
the spark plug hole...)
If you do you may damage the insulation inside the coil because the voltage will
rise until it gets to max or breaks down the insulation.

Use a good new spark plug (Bosch WR8DP). Gap it right (20 thou, .5-.6mm)
Make sure any wires connected to the frame are making good electrical contact
(clean the metal up)

If still nothing, get hold of a good running bike and *one by one* start
replacing parts off it on to yours until yours works.
