Then check fuel flow, float height, air leaks at the intake boot, and pilot jet cleanliness. Tiny dirt can create a very expensive-looking mood.
If this involves road testing, keep it legal and safe. A quiet car park teaches more than a panic run down a public road. That is how I would approach generic carbureted motorcycle sidestand switch shows normal but starter circuit stays open before spending money.

Thomas Spagnoli: workshop approach for generic carbureted motorcycle sidestand switch shows normal but starter circuit stays open
Before buying anything for generic carbureted motorcycle sidestand switch shows normal but starter circuit stays open, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.
The best next step is the one that can prove something. A test that only creates another guess is just a more expensive guess.
This is also the kind of method I teach in the free Motorcycle Mechanics Course here on the platform: observe, measure, confirm, repair, then test again. It is much easier to solve generic carbureted motorcycle sidestand switch shows normal but starter circuit stays open when the process is clear.
If you report back, include the measured values, not only whether it felt better. Numbers make the thread useful for the next rider too.
Good point about documenting the baseline. I took photos before touching anything, which may be my most professional move this week. I like that this turned into a checklist instead of a guessing contest.
