We would all love to hide the wires but it is just not possible.
On my V2 I have it so the wire rests on top of the handguard (bark buster) in the closed position, that way it is free to rotate as required.
Give yourself enough slack to reach wide open throttle (WOT), cable tie to the throttle cables but don't have your first tie too close to the throttle tube, about 5" to 8" down works, this gives the wire more freedom to move.

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.
