plug chops on a KZ305

I would like some help interpeting these plug chops.
The plugs had about 1000 miles on them.1st pic is a steady ride at 50mph for 10 miniutes. Hit kill switch and pull in clutch lever and coast to a stop.
2nd pic is at 80mph for 10 miniuts. (near WOT for tis bike)
3rd pic is after idling at 1,300 rpm for 10 min.
By the white insulator, am I too lean or to hot a plug?
By the black steel base, is this a sign of burnong oil?
