Good to see that you are still around. After the troubles with the forks leaking and the engine being done I thought you had given up on the ole' DR. Didn't you also buy a 950 Adv?
Great build up so far, I like the innovative solutions. Finally somebody has detailed what it takes to fit the 28L KTM tank, those will be a much cheaper source than the Safari supertankers. Now you also have a great base to slap a 640-Adv front fairing and lights on there! I assume you have seen Ron's awesome build where he used one?
What did it take to fit the WP shock? I have a couple of those lying around, they are not worth much to KTM people as they come stock on lots of them. But for the DR it should definitely be a nice improvement.
By the way, the ring from the forks sure looks familiar. I found the same in a set of SX forks I rebuilt last year. Must have been pounded pretty good!
