I have a 08 vision and 5th gear is so quiet and nice and 6th gear is like rock in a tin can for noise.
I was think how much noise is echoed of the gas tanks. I looked to day to see if there would be a way to cover them with something. It could be done with a fabric that has a glue back.
Maybe even some way to cover the front rocker box.
Any ideas besides buy a 2011
