ya, i have tried changing the trans oil, amsoil Vtwin trans oil, HD formula stuff, and Spectro 95w, in that order starting at 130 miles on the bike. rattle noise never changed (better or worse) my big issue is with the dealer... i know i can live with this noise and probably never have a break down related to what ever is causing this noise....but they told me it would go away after it got broke in... so i went back a week later and asked how many miles dose it take to break in the tranny, yes i know all this stuff but now its a game for me, he tells me a 1000 miles. so i drag him out to the bike and start it, rattle rattle rattle, i say to him bike has 1160 miles on it now what? he tells me put some more miles on it and see what happens, so i tell him no problem, ill drop it off in a couple months, 9100 miles on it. ball in their court now, im not mad and i realy like this bike but it will be traded when the next COV RGU comes along, 2018 i hope. till then they can have it till the weather in iowa gets better

also will add that my 13 RGC has never made this noise and i have beat the snot out of it and lost a out put shaft bearing @26k miles, that was easy for them to find and fix no other issues with that trans @49k now. my 11 RGC non CVO no noise at all with that bike
