The biggest problem here is having the KDS at hand and the bike half a world away.
Dave,
To refresh my understanding, you now have the kipass working normally? You can depress the key and turn on the ignition using either the fob or the passive like you could before you put it to bed for winter? Without bypassing the spring.
You are at a crank no start situation which you believe is no spark. How are you checking for spark?
Meantime I'll have another look through the KDS manual and see if we can work out the flashing security light.
