  1. How to make my SP 500 get faster?

    Polaris Sportsman
    Polaris Sportsman 500, 2012 model. It`s a perfect machine and i love everything with it, except the speed :) When i bought it, it was limited at 40km/h (registed as a tractor) How can I make the atv go faster? Is it possible to just press at the hose under the seat or something?
