Sissy if you are not talented like Stephen, Givi makes a nice tall windshield for the X500. I put on on my 09 and what a difference in riding comfort. I will go for the Michelin Gold Standards when I replace my tires on my X500. I put Gold Starndards on my wifes Aprilia S500. They improved the handling on both wet and dry roads and appear so far to wear better than stock tires. Can't comment on the jetting since my 09 has fuel injection. I would love to find a K&N air filter as well. I am getting around 50 MPG mixed driving. Love the scoot it handles well for a scooter and don't you love not having to shift or hold a clutch in traffic.
