Don't know how to post pictures on here, but if you want a nice looking "new" Enfield v twin engine, take a look at the Musket being built in the USA these days. I almost signed up for one myself, then 2 x 1912 v twin bikes/projects came up..... and I got distracted.
http://www.musketvtwin.com/home.html Take a look at the "process" "gallery" and "story" pages - can't say I'm in favour of the frame modification method, but the engine and it's stylised castings are to die for! From the site content, and the history of this guy's journey, you can tell he's obsessed!
