The mount I was using was a 1 inch ram ball with a 1/4 x 20 thread tapped into the original hole that came with steering head nut that came with a stem mount I had.
I will be switching to a much better setup. I have purchased just the bracket that attaches tot he gas cap ring from sportbikecams.com. This bracket comes with two tapped holes that fit the ram ball. There is no smoother place on the bike than on top of the gas tank. I can then use a variety of ram mounts for my Lowrance Iway 500c gps and my camcorder.
I have the stock 04 rear shock and for sure it is not the hot setup for a pace that on occassion drags hard parts.
