I sent my OEM seat off to Florida to be "Spencerized". It looks exactly like my old seat because he uses the OEM cover, but it is far more comfortable than the original. I spent three hours on it Saturday with no hot spots or squirming issues. That would not have happened with the original. Before, I was ready for a break after 45 minutes. It's not perfect, but well worth the money. The seat left Texas on a Monday, arrived in Florida on Thursday, and he had it back in the mail to me by Friday. I had it back on my bike the following Wednesday (nine days).
To get the foam replaced in both front and rear seats cost me $100. Postage will run you another $50-$100. He can't make the seat any lower on FJRs, but there is more of a cutout feeling where your butt contacts the bike. He used e-mailed pictures to get an idea of my riding position and then cut the seat accordingly. He told me the break in period was "three tank-fulls", but after 500 miles I'm satisfied with the results. If it gets a lot better I'll report back.
I also bought an Alaska Leather sheepskin pad for the seat. It feels nice but requires some getting used to... feels funny to be sliding around on the seat. I will say that the pad fits the FJR perfectly.
