I have a 2007 Dyna Streetbob, I bought a springer frontend from Mean Street Products, It is raked 3 degrees in the trees, it is 1 1/2 inches longer, and am still running stock front tire. I am now getting a really bad head shake problem from the front! If i twist hard on the throttle it does it, or if i'm cruising somewhere around 65 it only takes the slightest bump to make it start! Does anyone have a idea what could be going on? I have only been riding street for a year now, so i'm new to the suspension rules of the street. I would much appreciate any help or ideas to help correct this.
