Just a thought...
But Jack your bike up where the rear wheel spins freely and give it a little gas, same with the front but just spin it as fast as you can. See if you have any bounce or sway in the rims.
Just a thought
Hope you find your issues

^^^ Good idea, the bags may just be exacerbating the problem by adding lateral weight to the back end. They may not be the cause but making it noticeable. Also, if the weight is not even with what is stored in the bags it will make it worse.

Did you ever replace the wheel bearings?

So, you've modified the geometry and you have handling issues? Who'da thunk?
Wanna fix it? Return it back to stock and don't exceed 55 mph. Sorry, but it's true. If you wanna run "80ish" (which usually means 110ish, then get a bike designed for those speeds. Harley don't make one, anymore. Triumph might be something to look at though.
You took one the *best handling HD's* and screwed it all up by listening to people that wanted to make a buck off of you. Well, you did, and they did. Now look what you've got. A bike that may have dangerous handling characteristics if an emergency maneuver is needed at speed.
Again, return it to stock config. It'll be safer for you in the long run.
* best handling HD is as compared to the rest of them.

Think about it for 1 measly minute. Just one. You'll get it, I'm sure. (Well, I hope so, anyway.)
Make sense yet?

Do you honestly think that Harley put a lot of thought into the handling aspects of the thing? Seriously?
Had they done that it would have come from the factory with better suspension, heavier fork oil, shocks that actually worked, more ground clearance for realistic lean angles and a better motor mount system.
But instead Harley did what it always does and built a bike that from the factory is too low, wobbles dangerously in curves has incredibly mushy suspension and a host of other issues that had to be addressed by the aftermarket.....But hey, They looked cool.
To make the bike handle better you have to change some of the geometry that you think is so spectacular and address the motor mount first and foremost.
The Dyna was a poor replacement for the FXR which was without dispute, the best handling big twin that the MOCO ever produced. The Dyna on the other hand was designed to be cheaper to manufacturer....Period.
The Dyna can be modified with the aforementioned aftermarket fixes and turned into a good handling motorcycle that rivals the FXR in just about every way.
But don't try to pretend that leaving it stock is the answer to this guys issues.

Nope....Making modifications to the suspension is one of the best things you can do with a Dyna.

Yes, I've already posted that modifying the FXD can provide great rewards.
In the defense of H-D, however, they were not just stupidly making the Dyna what it is in stock form. H-D is in the business to sell motorcycles and they have done good job of that. Most H-D riders WANT the sort of bike that they produce. I guess they figure to produce what the masses want and let the fringe contingent who wants high and compliant suspension etc accomplish that in the aftermarket.
When H-D produces a performance handling bike, it seems to fail in the market. I had a fantastic VRSCR for a couple of years when they first came out but those bikes were a sales failure. Ditto for those XR Sportster series bikes a few years ago.
I am very familiar with the FXR series, I built a hot rod version once that ran like stink. Great bikes but they got a lot of negative feedback from the traditional Harley customers because of the triangulated frame etc. The Dyna was designed to look like the previous FX series and it does that. As the quoted post states, a Dyna CAN be configured to rival the FXR. Mine does.
Anyway, back to the thread topic, a wobbling Dyna is a problem. Something is wrong.
The wheel bearings may be fine but I'd change them out for quality items as a precaution.

But good luck in finding your wobble.
