550xp performance

  1. 2011 550xp performance cam

    ATV Performance Modifications
    I saw that speedwerx makes a performance cam for the 2011 550xp. Does anyone know what kind of power gain can be expected from a cam upgrade? I would like to do this with a slip on exhaust, k&n air filter, and a power programmer. Stock up is 42. Thanks for the input
