I'm with the others and think it is more likely plug creep as the wires in the power socket are held in place with epoxy resin.
The dash on the V2 is very easy to remove if you wish to have a look.
2 button head bolts and 2 plastic push pins to remove and you are in.
Behind the centre of the speedometer is a plastic pin that is pushed into a rubber grommet, that is what is doing most of the work to hold things together, a gentle tug on the speedo and the dash is free, now unplug the wires to the speedo and the wires to the power socket and you are good to go.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
