As you mentioned the two different spark types of your kids bikes I assumed that you run those for testing and they fouled. But BR8EG is the correct spark. If it fouls the problem lies somewhere else. Did you change the oil type recently?

My GP fouled at least 1 plug per hour until JD advised me not to use Amsoil Saber anymore. I didnt believe him and changed all components of the ignition system. All! Including stator and ECU. Nothing helped. After talking directly with Amsoil I changed the oil and it never fouled a plug again in the next 80 hours. Strange things can happen... That's why I asked plug, gas and oil type.
