And for you folks that might be interested, I've found that "Doc's Chops" is now called "Hageman Motorcycles" - http://hagemanmc.com/ - after the owner/builder, Greg Hageman.
Make sure you make note of the "Hageman" logo... Looks just like the original Yamaha DT-1 tank badge, doesn't it?
It's worth checking out his "Current" and "Past" projects. The guy definitely has a unique eye.
