I think its time to do a starter battery voltage drop test . Just hook up a voltmeter across the battery and monitor the voltage . When you hit the starter the voltage will drop to some value during cranking lets say 11 volts. The ECU/Ignition system will stop working at some lower level. We need to know what that level is. Dimitri stated the same thing , he is in the Netherlands I think. Anyway , at some value under 12 V the bike does not fire but it will crank over. So , This value we need to know . I will perform this test on my bike and I will report back the value of the voltage drop at the battery during cranking. Also , If the battery cables are gauged too small this will worsen the issues. And lets not forget bad or corroded connections will do the same thing. Tony
