Thinking about this, the Trophy has a system that senses when a refuel
takes place : the fuel level sensor senses there is a higher fuel content
when the Ignition is switched on, than there was when the Ignition was
switched off, and goes into its calibration mode for a few miles
to determine the new fuel level.
Perhaps the same thing is happening with a less than full tank,
if you stop and turn off the Ignition while the bike is upright,
then you put the bike on the Side stand, and switch the Ignition back on
while still on the Side stand, because the bike is leaning over it probably
registers a different fuel level than when switched off
so goes back into recalibration mode ?
