If you mean 0.34 mA maximum leakage current is right. Then his current readings are well below the maximum. Honda doesn't specify a "typical" or normal leakage current reading, only maximum allowable leakage current.
Right, it's only about 1/10 of the given 0.34 mA by Honda.
The number, Honda is tellin us, is not really a leaking.
It's a max. total of the specifyed load of the closed current, that the bike will use, if off.
The watch, which is a total digital unit here, is one part of it.
And this closed current varies only a little, because of the tolerances of electric components.
Out of my understanding, only 10% of that said 0.34 mA
is to little.
It's now reading anywhere from 27 microamps to 31 microamps; or 0.027 miliamps to 0.031 miliamps
Even half of it, only, would make it suspicious!
So I would check, if the meter reads right/ is good enough, for the job.
As smaller the range, as more the influence of the tolerance/quality, of the meter.
What is the reading from the batterie, if fully charged with a charger, yesterday, and testet, today.
And how is that changing, putting it back in the bike and only turning the key for some minutes?
How does it restore, after the load?
You bike can't charge the batt, if there is a cell down! 12.5V on 5k rpm looks to me, that maybe 1 cell is down, already
