You can calibrate the speedo rate by moving the drag-cup assembly
relative to the magnet, assuming there's provision to do so.  But the
odometer rate is fixed by the internal gear ratio (and doesn't change
over the life of the unit), so changing it means replacing
gears.  Maybe the shop could do that?  It would at least need to know
how much change to make.
