If you lowered it with the shorter HD shocks, that's most of your problem...... HD got the one inch of height out of these shocks,( stock on the '09 Street Glides), by taking it completely out of travel and then valving the hell out of them so they do ride very stiff. Not much you are going to be able to do about them as is.
I would suggest you contact the people at Phoenix Customs/Bitchin Baggers and let them help you out. I lowered my '09 RK one inch with only 1/4 inch of travel loss..... the reworked shocks ride every bit as well as the stock full height ones did, if not better. Cheap money too......
