I just broke in my new 2009 Street Bob. It´s all stock but it won´t run past 140KM (80MPH) per hour. It´s 96 cubes and 6 speed trans What gives? I have a 1999, 1200 Sportster Custom that goes straight to 160KM (100MPH) with no problem. I got the Sporty with a Screaming Eagle Stage 1 and this thing just flies from the first day I got it. What do I need to do to make my Street Bob better than my Sporty?
