Now you're talking...that would be my preffered route, you get a modern engine and fuel injection system with the Buell power plant, support and a readily available parts network. A salvaged Buell can be had fairly reasonably with a title to make registration easier. I've always had a thing for the british twins and the early twin Hondas.
What are your plans with these? Are you going to ride with a buddy and cover some miles or just hop around town and be a social butterfly? If you think you're going to cover some miles, I'd really steer you away from anything with a hardtail...you can get the same look and style with some of the more custom soft-tail frames, your guts and back will thank you for it.
Just tooling around town and to work when it's nice out.
Social Butterfly? I like that...
Maybe I can get Kenny to do that as my next tramp stamp???
