The stupid kill switch has very small parts. Be extra careful. Electrical connections are often the first suspect.
I have had the starter relay fail, the connection to the ignition box, the connection to the head light relay, the main connection near the steering head, and the kill switch, just thunked, and the key switch. Not to mention blown fuses.

On my 41 Ford tractor, the resistance from one side of the amp meter to the other, was large. The connections looked good, but they were not shiny. The connections get a sheen type of cover on them, that resists volts. On Yami, the fuel mileage jumped up about 4 mpg, after fixing bad connections.

I suggest you unplug and clean every piece in the ignition wyring. But if it stays running, maybe not.
When I fire Dark Vader, I will bypass every stupid connection. Will just be the key for on and off.

If you can, I'd keep it on a battery tender. It makes a world of difference on cold starts like that where the bike has sat for a while.

This is so critical.
Everything I own is plugged in. The 006 Suzuki is still running on the original battery.
My Dodge van draws 3/4 of an amp at rest. The Triumph and Suzuki are running clocks. The tractor has a solar panel charging the battery. The boat has solar panels.
Back when I was not as careful with my batteries, the ones for the bike, or bikes, would not last.
If a bike is being used on a regular basis in the summer, I may let it sit for a week to ten days. b4 plugging in.

My next goal is to keep them all warm and dry during the winter.

I did not mention above. I hope it is fixed and keeps on running.

I don't put it in the top gear until I reach 55 MPH, or more. If I'm just cruising down the highway, enjoying the shade and the curves, and there is no one riding my donkey, I'll be in third or forth gear.

55 !!
Noddy does 55 at 5000 in third. 3 more gears to go.
Bluzu is in kilometers. 100 kph is just over 60, and 6000 in third. 3 gears to go.
Deep Purple is doing 6000 at 60 in top gear, in this case fifth. But he is just a little guy at 400cc
It's how I know which gear I am in.
