I have a new 04 with about 600 miles on it. I have noticed that there is a serious harmonics vibration at between 4600-5100 rpm which equates to 90mph-106mph while riding in 6th gear. Every time I hit 90, it starts to humm and vibrate pretty bad. Almost feels like something is out of balance inside of the engine. It doesn't matter what gear I am in, just has to be between the certain RPM's so that eliminates a possible tire out of balance. Any one else have this issue? I might take it back to the dealership but I know I will get the run around....
Thanks for the help
