no spark

Hi folks got an FE550 few days ago, had a play on t now ive no spark seem to be getting resistance and continuity readings at both the stator and the coil so im suspecting its the cdi unit cdi number is 80039030000 i believe the bike started life as a 450 but since had the 550...

Hey my 570 suddenly died when i rode it on the street... Now the spark is gone... Have measured all the fuses..OK....fuse 2 has 12v all the time..1,3,4 has power when i crank it... And the ECU gets power as well.. Have changed parts: Ignition coil Stator Regulator/rectifier...
