I thought I would throw this out there and see what the opinions are. I bought my '05 FXDI this September, and done the following so far (in addition to what was already done by the PO):

-Replaced grips
-added larger brake pedal
-added k&n stage 1 AC
-installed fuelpak
-added detachable windshield
-added a few chrome parts
-swapped taillight for led
-installed layback plate w/ signals

On the list of upcoming plans, in no particular order:
Bags - leatherpros
New Pegs - HD heel raiser
Seat - sundowner/touring
Led signals - custom dymanics
Install mini apes
Combo gauge - 70900274

Just throwing it out there - it's a work in progress. Any comments/feedback welcomed...

 

The sundowners are comfy but imho their fugly. If it matters they will also set you higher and closer to the tank. If yours are stock you should add shocks to the list

 

changed front and rear fender, lower front forks,drag bars, lowering shocks, big radius pipes, custom cut struts, new paint, engine chromed out, whats next maybe more of a rake and new seat

 

Suspension would be at the top of my list....
