My list wasn't terribly long this year:

Andrews 48H cams
Gaterman lifters
S&S Quickee pushrods
Torrington cam bearings

Kuryaken adjustable passenger pegs
Ultimate Seats tourpak relocator
HD Premium tourpak latches

Doing the cams last weekend made me a little nervous, never having done it before. But the bike is running awesome and the valve train is as quiet as stock. The exhaust note is considerably louder now though, more than I like, so I might try wrapping the baffles. One thing leads to another I guess!
