A little common sense should be applied to this situation. How old is your battery? If it's only a couple seasons old, I wouldn't suspect it.
If it's 4 years old or older, then you're living in the bonus time. A friend insists on battery replacement on a schedule, while I typically
end up in some catastrophe.
To test the stator, disconnect the lead from the R/R. Start the bike, and then apply a voltmeter across any two of the output leads from the stator.
When my stator - R/R connection initially burned like so many of ours have, I stripped the wires back to before the char, crimped on new blade connectors,
and continued to use it. Eventually, that also failed and I got a new stator and R/R, as well as a battery.
If the stator - R/R connection looks healthy, then it probably IS healthy. A voltage check per above on the stator should add confidence.
I have tolerated some pretty terrible battery behavior, such as 12.9-13.1V while riding and sluggish starting, before full failure. It's kinda stupid.
Once you replace the battery and reacquaint yourself with healthy starting and running, you'll wonder why you ignored the symptoms.
