I have the same problem with my Roadking except it wasnt dropped. I did a full alignment of rear tire to engine, aligned the rear tire to front tire, aligned the engine and replaced the front motor mount. Nobody seems to have an answer, that I've talked to anyway. If you find a cure let me know, If I find one I'll let you know.
SOURCE: first ride of season on 2007 dyna fxd. something
check air pressure in tires first the look for loose bolts check wheel bearings anything thats bolted to the front end

Hard to diagnose, but if you have a bad engine vibration, you will be able to diagnose that when stopped and just revving up the engine. Moving balance problem can be easily out of true wheel and or needs balanced. (You can make your own balancer/ wheel true guage our of a couple of 8X8 posts with axle size hole drilled in each one) If you clonked a curb or pot hole at speed this can easily happen. Hope this helps you with your scoot, Rick

One thing you could try is a "fork brace" or what some people call a "tweek bar" that ties the two sliders together. This reduces the amount of flex in the front forks. We used to run them on our dirt bikes years ago. They do help stabilize the front end.
Also drop your front tire pressure to 30 psi and look for any unusual wear patterns on you tires such as cupping. Take the wheel off and have it spin balanced as well. You can also change the fork oil in your forks. I run PJ1 30 weight in my Wide Glide. It's a bit on the stiff side but it sure helped the handling as the bike no longer bounces and dives in the turns. I also got away from the Dunlop tires. I now run Metezler 880's and they seem to handle the turns better but I think the Dunlops had better braking characteristics.
Good Luck
