Michael4012 is correct. The '10 model was referred to as the Gen 3.5 model since there were only 4 differences. Muffler, nose fairing redesign, and associated side fairings. The motor is identical between the '08-'10 models. Which means the throttlebodies are the same also. So whoever told you that was mistaken and thinking that was in reference to the Gen 4 which came out in 2011.
Gen 3: 2008-2010
Gen 4: 2011-2015
