You may not have an ignition problem. The ignition does have a timing curve,the electronic spark box varies timing with speed.

the way to check the coils is with an ohm meter... the values are listed in the service manual...
the ignition timing set procedure is also described in the service manual...
for your bike i don´t know but for the kx125 02 the timing is 13º at 10010rpm, just to give you an exemple
