I done it a couple of years back, delivered to the door, even got to keep the crate it can in.
See my post here (5th down).

Saved about £880, bit a paperwork, but you can do it all yourself.
rode first winter without carb heaters, didn't have much of a problem.
Got UK lights off Ebay £50, and clocks from a breaker £90.
also picked up another set of uk carbs last winter (mine needed a strip-down after 80,000 mls) for £35 and they had heaters.
So of the £880 I saved it cost me £175 to change it to uk spec, still a saving of £705.
would I do it again? well if I was looking at a new bike, then if the sums worked out at asaving of more than £400 then yes. ( Oh, and just for info Suzuki will honour the 2 year warrenty, but you don't get the 1 year AA cover(NCI £34 a year)).
Cheers Mark.
