Hi Anthony, I have a 2015 xt1200z and I love it but I cant stand the twitchy throttle response and heavy engine braking. After doing some research I was glad to read I wasn't alone and it seems like you are the person to contact. Can you please send me a email at Tgoldbin84@yahoo.com I would love to see what I need to do to have you work your magic to make my bike even more enjoyable than it already is. Thank you!
