If the kill switch is on and the engine has been disabled, the gauges do not sweep and the fuel pump doesn’t cycle when the ignition turns on. I’ve found that, if I start the engine while the fuel pump is cycling sand the gauges are sweeping, there’s a moment when the revs are abnormally high.I don't as a rule use the kill switch, however the gauges DO sweep with the kill switch either on or off when the ignition is turned on. With the kill switch on the fuel pump does not cycle.

When the key is turned on, it runs from one end of its range to the other to learn the limits. If the bike is started when it is still going through its cycle, it could/would cause the high idle.OK- as a test I'll delay hitting the start button once I've turned the ignition on & see what the result is
