The bike ran fine until I was on the way home when it felt like the engine cut out. The revs dropped for a moment, less than a second. The HISS, engine and oil temperature lights all came on, but went out after perhaps a second.
Cormanus definitely not fuel, it's electrical and i would think the red e-stop would be a good candidate, water in the switch could have an effect, easy to try if it happens again and see if the symptoms are the same as you described above.
Unless work has been done on connectors in the past, maybe in the headlight area, the connector for this switch lives inside the bucket.
Another culprit could be the sidestand switch; sidestand plus in gear stops the engine as we all found out, have a snoop in that area, is it loose, any damage to the wiring/switch, connector not corroded and clean?
The sidestand switch "talks"to the e.c.u. I have not measured the voltage on it but could be either 5 or 12 volt when the switch is open ( down position i think ), the switch is connected to ground on one side and to terminal b22 on the e.c.u. and also connects to one side of the clutch switch, in other words ; to test the sidestand switch you would disconnect both spade terminals from the clutch switch and connect a voltmeter on the one that changes the voltmeter reading when the sidestand is operated with the ignition switched on.
Of course the fact that it works does not mean it is reliable........
So two options to try out for next time, all the best.
Apart from the engine stopping what lights come on if you operate the sidestand whilst on the centerstand in gear ( and disregard the oil pressure switch )?
If the fault was in the main switch/fuse the meters would have swept so that is not a plausible candidate, we are looking at a safety circuit fault best as i can figure from what you tell me and it is highly unlikely that any fault codes have been "set" in that case.
