I don't see this posted anywhere?  Please clarify.

THE SOLUTION that will end all our rattling about the speedometer rattle noise . . .  

Rubber grommets 9/32" size from Home Depot (available in the specialty drawers that they have for 72 cents each).

Insert  into the holes on the three brackets attached to the gas tank. Apply a little spit first as it will help you get the  grommet to seat easier along with pressure from your thumb. Apply a light coating of a lubricant preferably compatible with rubber on the little steel rods that hold the speedometer housing, then add small plastic O-ring washer (also from  Home Depot available in the plumbing section or the little specialty drawers in the hardware section) placed between the spring and the grommet, and wah la----no more squeaking noise.  

The wear on the grommet should be minimal and  offer a longer solution that the heat shrunk covering on the rod that will rub against a sharp edge of the bracket.

Hard to believe that Suzuki did not pre-install grommets during the factory assembly--they should  be standard OEM!!!!
