125-200cc 2001 Wre 125 No Spark - Electrical Issue Please Help!

Hi there guys. New to Huskys and this site. Recently purchased a 2001 (cagiva era) WRE 125.

Ran ok when I bought the bike but after a 2 hour drive with it on my trailer (big vibrations) in torrential rain I have not been able to get a spark.

When I kicked it over at home at first I heard a pop pop of the exhaust so it fired a couple of times and then since nothing!

Close to the end of my tether now as I have checked and replaced plug, lead, cap, ignition coil, ecu, checked ignition barrel and the measured resistance across the stator pickup and main.

Really at a loss now and would appreciate help!!

Yours hopefully, Alan.
