Bama Bagger, after mounting mine in a couple locations, I finally settled on mounting it to the Clutch reservoir, with RAM mounts.
This is the part that mounts to the TOP of your Clutch Reservoir:

Then you want to use the shortest link you can find, which is generaly the 2" link, that connects the ball to ball mounts:

And finally you need the ball mount that mounts to the backside of your Garmin mount:

Now, that is how I did it. You may find a different way to do it, but I am very happy with this method. It mounts the GPS in the correct location for me. It is solid, does not move or vibrate, and can be adjusted to view.
