I have read about it lots on another forum - it's apparently a fairly easy swap. Yes I've considered it, probably would have gone forward if I wasn't saving up to buy my 1st house, but that's another story....
anyways, part list (not mine):
Engine mount (with slot for choke) ……. 16315-99
Choke cable ……. 29229-88B
Choke elbow ……. 27580-88

1. Stock Petcock- 61338-94D $58
Stock CV40 Carb- 27412-99D
You will also need the ign module of your choice.
Total price for this parts list (using zanotti's) is roughly $300, not including the carb and ignition.
You can find stock parts for cheap on ebay, or, of course there's new high end components if that's your way. Depending on what components are in your engine...If it's stock or stage1, i think you can buy the stock ignition and just plug and go. Upgraded engine likely needs an adjustable ignition (daytona twin tec is popular) or similar.
There's lots of info about this swap out there, just google search "harley efi to carb" and you'll find plenty of links.
