Bike looks super clean!
You can move the shock mud flap over and perch it on the swing arm when removing the shock. That will make it easier than the you tube video.
Get a cheap front inner tube, like a Chen Shen, and cut a piece to cover the wiring loom from the battery up and over the motor while you've got it down this far. This will prevent chaffing from rubbing through any wiring that that is exposed.
