I have done this to both my 01 and my 05 and it works. The stock seats have too much slope and throw your wieght forward to your wrists not to mention the parts that are plastered to the tank.
remove seat
remove staples that hold cover on, leave staples at back though.
pull cover back and remove foam.
using hack saw blade or bread knife cut foam protrusion that goes into seat off as seen in pic.
I also put a 1/4" foam piece under the front 3-4 inches of stock foam pad to level it a little more.
put foam and cover on and secure with 1/4 or 3/8" staples.
Seat will appear stock but will level out and sink into pan becoming slightly concave which matches your a$$ better.
