I've had my 2012_Ultra since August, and I'm in the middle of installing chromed SG wheels and chrome lowers/flush mount axle. Will install Klockwerks Ergo bars and solder some LED's in the gauges, used J&M amp/speakers w/Hogtunes woofers in lowers while all piece parts are being painted during the next couple of weeks. Has ~2600 miles on it so far.
Already added Harley iPod and Nav w/dashpad, Thundermax ECM, Fuelmoto ceramic headpipes/Jackpot mufflers (perfect to me, not too loud, not too quiet), SE Ventilator AC, Streamliner pegs, brake, rider/pass boards.
I just want to get it the way I want ASAFP so I can ride the thing.
Thanks to all who share great tidbits of information, I will be sure to comment when I have something useful to add.
