Welcome to the site.
Ive heard others complain about a high speed wobble - and it is usually caused by a batwing fairing that has been mounted to the forks, rather than to the frame of the bike. I suppose the easiest way to fix it is to remove the batwing fairing. Or drive slower...but who the hell wants to do that?!?! LOL!
Good luck, and enjoy your ride!
