You do not have to remove the drive shaft for a stator replacement. You do have to remove the bevel gear case however in order to get room for engine tipping.
Once you have the engine tipped or removed, if you still want to remove the driveshaft you can pull it out from the front of the swingarm. If you do remove it you will still have to take the rear wheel off since there are o-rings and springs that must be set in place to reconnect the driveshaft to the final drive.
Removing the black will be a pain since it is powdercoated on. If you want silver, your best bet is to get some high temp paint and paint over the black. Be sure to mask off all openings of course. When I had a stator cover powdercoated, they used a "camaro silver"
