magneto test

hi so this week put my motor on a new frame i put a new pipe and a 36t sproket and new head gasket so this moring on my way to school i got about 5min from my house and the bike stared to warm up lol it still -6 outside her so one it warmed up it just died pulled the plug and am geting no spark...

I'm having electrical problems and I don't have any testing equipment. a buddy of mine has a fluke meter. can anyone tell me if we can test the cdi and the coil with a fluke meter and also how to do it and what readings we should look for?
