Sounds like you are diagnosing it well. I'll add some comments that may help. Anyone else, please correct me where I'm wrong.
In all three cases when I turn the key, the electrical turns on, the gauges light up, the dials swing and settle into natural. This is normal whether in gear, sidestand up or down, engine switch on or off.
I then push the button to start and nothing happens. it doesn't click or whir or try to turn over. Simply nothing. This is normal if the sidestand down with trans in gear, or if run switch is off. No whir from the fuel pump means it is not safe to crank.
In all three cases I was not starting from cold. Twice I had gotten to my destination, left the bike for 30 minutes or so, and then experienced the fault trying to start it back up. In one case I had turned the bike on, moved it only about 30 feet, turned it off for 1-2 minutes, and then experienced the fault trying to start it again.
Sometimes (should be always) when I turn the key to the "on" position the bike makes an electrical whir as the electronics kick on (the fuel pump maybe? - Yes). That didn't happen any of the times I experienced a fault. No whir from the fuel pump means it is not going to crank. Maybe because the bike is already warm? No, it's a cranking circuit interruption. I would have to trouble-shoot more to figure out when exactly that happens and if it matters.
In all three cases I let the bike sit for 5-10 minutes, intermittently kicking the kick-stand up and down, flipping the kill switch on and off, and pushing it in and out of neutral. Eventually it started back up. It will never crank until you've heard it whir, which is the fuel system being pressurized initially.
On two of the times I remember hearing a slight electronic *click* the last time turning the key back to the "on" position before the successful start. Do you remember hearing the whir? It should have sounded. Possibly a loose battery connection or faulty battery. I've had a faulty battery cause similar or same symptoms
When it does successfully start it doesn't chug or struggle at all. Starts up clean That should be expected.
Have any of you experienced this on your CBs or other bikes? Or does this sounds like something you know and can diagnose? Any ideas for tests or troubleshooting?
