The only advantage an Evo has over a good running Shovel is the 5 speed and bolt on intake manifold instead of clamps and bands. That's why I didn't even look at used bikes and went straight to the TC88. I paid $12k otd and I'm in it for another $1500 or so with SE filter, jets, pipes, forward controls off a FXWG, a short sissy bar and leather bags.
The bike is all day comfy, can haul some of my crap around and runs like a champ and looks pretty sharp too. I wouldn't mind having an XB9 for a play bike........maybe next year.
