okay , I have the same problem and maybe I can help you save some money.
First off I started with a new Sun Downer seat from Harley, shaved the seat area out and put in a gell pack. We also shaved down the sides and re coverd it with Lizzard. This gets you 1.5 to 2.0 inches for $750
Bought lowering suspension blocks from ebay, using the OEM air shocks. Although this will allow the shocks to angle back causing a rough ride and fender rub. This gets you 2.0 for $45.00
New pair of riding boots and had a thicker sole put on. $150.00
Replaced the OEM air shocks with Progressive 940's, using the lowering blocks, rough ride..and fender rub. Raised the bike 1.5 with screwed down and will cost you buy them on ebay for $500.00
Replaced the 940's with Progressive 212's 11.5 inch shock and removed the lowering blocks. Rough ride but at least i can touch the ground for $220.00
I've been dealing with this issue since October 2008 and 37,000 ago.....good luck.
