Larry keep working at it. The idea is to get the ride as comfortable as possible for the trike it is. Things to think about, NO TRIKE will ride as good as your heritage. Your 2 wheeler went down the road pretty much with BOTH tires in the same track. A trike has 3 tires of which NONE is in the same track as the other 2. So you have 3 times more road to feel then on the 2 wheeler.
So things to keep in mind. As far as road feel independent rear suspension will feel better then straight axle. The longer the wheel base will make for a better ride. Independent suspension will not handle the twisting roads as well as a similar straight axle.
TRI glide/Free wheeler have had many members make changes to them to improve the ride over stock. Riding a trike takes at least 400 to 1000 miles for the new rider to get a true feel for it. If you still think you want better go to DK Customs (ad this web site) Kevin has done extensive testing of ways to improve the ride on the Harley Trikes.
Good luck give it a chance to grow on you.
