I have a vibration up around my gauges and windscreen. Can't seem to find what is making it. Only happens at certain RPM's around 4000. I have taken off the windscreen, Still happens. I have taken everything off that I can and put it back and nothing seems to help. If I grab a mirror while riding it stops or if i push up on the windscreen it stops so I know that it has to be in there somewhere but I'm lost. Any body else had this problem please help!!!
