By way of introduction, I took possession of this beautiful '00 Gen 5 last year, 2020, so I haven't had it long. It has around 46k MILES (74k kilometers) on odometer. The PO was a friend of mine who died suddenly of brain cancer. He bought it new and took very good care of this machine. I have since installed a charge port to the dash (switched power from the battery), new tires (Metzler Roadtec 01), battery, brake pads, chain and sprockets (they were hard to come by, at least the rear), engine oil and filter (10W-30 dino juice), and flushed the brake and clutch fluid. Regular maintenance kind of stuff.
The bike runs and drives great, pulls hard, and generally runs like it should.
Except for the other day when the neutral light wouldn't come on when I tried to start it. The gear box would go into neutral but the neutral indicator light on the dash wouldn't come on. Therefor, I couldn't start it with the side stand deployed. I could only start it seated with the side stand up and the clutch pulled in.
Ideas on where to start? I have the full shop manual but I haven't started to dig into this issue yet.
