Hello,
I have received a GATES 91107 Krikit V-Belt Tension Gauge:
https://www.rockauto.com/en/moreinfo.php?pk=101690&jsn=253
and checked the drive belt of my FXS: the belt seems over tight, since the plastic lever of the Krikit tool does not move before the "clic", meaning that the tension is more than 70 kgs (the recommended value is between 20 and 30 kgs).
That is strange that all the bikes coming from the factory seem to have over tight drive belts. Should we leave them like that or should we reduce the tension?

  I had the same experience.  At first I thought I was not using the gauge correctly.  I don't know how tight the belt was, but it did not visibly deflect at all. 
  You should definitely reduce the belt tension to within spec.  I think the over-tension can cause premature bearing wear.

Have you tested the belt using the  http://electricmotorcycleforum.com/boards/index.php?topic=6696.0 "carbon drive" app? Just to see if it is consistent with the krikit indication....

Thanks for your comments.
Today I took some time to reduce the tension of my belt.
I have used both the Gate / Krikit tension gauge and the Gates' Carbon Drive mobile app.
I have written the details there:

Temperature has a lot to do with belt tension. Ambient temperature where I live changes 50degF or more from 20degF overnight to 74degF daytime. I think my belt could be tighter, but the day warms up and it's too tight again. I might be imagining this or there is some other reason.
