hi there. i have read about all the reviews on the 2014 and i am mostly interested in 2012-13 owners going to the new 2014 cause i'm realy considering changing my 2012 for a base 2014 but i just dont want to spend money and feeling like it's the exact same bike besides the obvious upgrades. i love my 2012 but some things i realy dont like seems to have been corrected. my concerns are mostly mecanical. i will tell you what issues i would like corrected and your input on these will help me make the decision as i am not able to find a demo to test ride. first thing is the clutch basket harshness, vibration ?. then the smoothness of fueling and general smoothness of the engine ?. it's suposed to be more refined. is this fact? i have also a vibration comming from the driveshaft at above 80 mph speeds and i have read somewhere that some tweeks have been made to the driveshaft? like i said before i love the bike but dont like the low speed caracter of the engine as it knocks vibrates and as a harsh power delivery. thank you for your help
