Hi grbrown.
I have always admired your FLHS it looks like a formidable piece of equipment. Thank you for the recommendation for the TrueTrack, As you have found the Dyna platform a ton of fun to play with, I found it so much fun I fell off the deep end...
A partial list of chassis mods are, new engine mounts, CCE adjustable front engine bracket (in the mail), Allan Sputhe Posi-Trac and a heim end link to replace the Harley rubber sleeved upper engine link, .312" factory offset removed from the chassis at the rear wheel (that was a lot of work), Works Performance adjustable ride height (13"-13 1/2") Pro Racer shocks and custom valved drop in cartridge kit for the forks, Speed Merchant preload adjusters, Fat Bob fork legs fitted with XR1200 Nissin calipers and master cylinder, Harley Sun Star rotors, Earls Speed Flex brake lines, GPR steering damper and billet upper triple clamp, every bearing in the chassis replaced with SKF or Timkin, and a bit of machine work to make it all fit. Next up after I recover from christmas is a new set of alloy laced wheels 18 X 5.5 with 180/55ZR18 rubber and 18 X 3.5 with 130/70ZR18 rubber

I've "converted" a couple of FXDC's along similar lines. I'm currently riding a '12 model. Just finished a 2700-mile Blue Ridge Parkway trip with it.
Low Sportster bars, bar-mounted tach & temp, fork inserts, Sputhe Stabilizer front & rear, Ohlins shock 13.5, 103 displacement upgrade, open intake & exhaust, SE204 cams, MLS head gaskets (9.9-10 comp ratio), V&H FP3 module. The thing runs with any of the several European bikes (BMW & Guzzi) that I have.
This "build" is designed to make the bike haul butt and handle curves and it does it well for only a moderate outlay of cash.
I find the FXDC, Super Glide Custom (now discontinued), is a prime candidate for such customization. Vibration on my Dyna models, so configured, has been very mild. The things are smooth at speed.
Looking forward, I hope to see some improvement in frame design from H-D. The biggest problem with the H-D frames have been the rubber mounting system. The inherent flex this configuration adds to the frame works against the handling stability of the bikes. It's a big reason why you feel wobble when leaned over hard in a curve on a stock bike. This has been true for both Dyna and Touring models.
To make a H-D handle competitively with other road bikes, a lot of work must be done to overcome the problems of the rubber mount system.
Now that all the new engines are smoothed out with a balance shaft, I am hoping that the rubber-mount configuration will be minimized.
The truth is, H-D has done a good job of building what sells. This forum site and H-D's sales numbers underscore the fact of the market that most of you guys do not want a handler for fast curves.
A great number of H-D riders apparently want their bikes slung low with high ape-hanger bars and feet way out front. By the way, those apes only accentuate any vibration that telegraphs through the frame from the motor. They also make for awkward curve handling since the increase the turning arc of the hand location. Still, if you want apes, that's fine. It's all about what the customer wants. Ditto for the ground-dragging suspensions.

Hi Bwoltz,
Sorry I took so long to get back to you, I pretty much have been living at work for the last 4 days.
Palomar sounds like a hoot, late December to early January I should be up and running.
I'm working the "list" on the bike, the only problem I have is every time I knock an item off I seem to add two.
How do you like the G850 Bridgestone, as the ZR Exedra's look like a great buy, probably the tires I will go for. What sold me on the Exedra's is the diameters, front 25.3 and the rear 25.8, with the 18 inch rims. I am hoping this will handle, as the rim/tire combo is inspired by the early 1980's AMA superbikes which were running fairly lazy roadster steering geometries.
