I've done a batwing fairing on a conventional front end like that and you will not like it... The conventional front ends use a triple tree that has the forks in front of the neck. The baggers have reverse style trees for a reason. when the fairing is mounted on a conventional front end any variance will be exaggerated on the front end. It will sway back and forth and get a wobble. The reason HD did the reverse trees for the baggers is for that reason. The neck is "pulling" the front end, not "pushing" it. The pulling motion does not amplify the sensitivity of the front end dynamics. When I did my set up like yours, I was struggling to figure out what the deal was. I even built a custom mount and put a sportbike steering dampener on it, which helped, but still didn't fix the problem. It would wobble so bad that it was unsafe. Go the road king route and save you a ton of money and headache, not to mention your life! It just doesnt work very well no matter how you do it. You can even call the guys that sell fairings that mount on softails and dynas and they will tell ya the same thing. They make a smaller fairing to catch less wind but at highway speed you will always get a wobble with that style front end and fairing...
