This probably belongs in the Technical Discussion forum so I have posted it here. Any advice would be appreciated.

Just wanted to float this experience out there and see if someone has experienced the same issue. Bought my Road Star in late 2007 and loved it. Big step up from the Boulevard I was riding. Faithfully brought it in for it's 600 mile first service. At that point the bike had your typical big v twin engine noises. No problem there. Things slowly went down hill however. The bike has developed a chatter when maintaining speed in any gear. It sounds like the valvetrain but it is not constant. No chatter at idle and no chatter under load. Only when maintaining speed. Hit the gas and it goes away. I've tried the headlight fix, the tank rattle fix and the ring free treatment. Not any better. Tried different oils and fuel and that didn't lessen the chatter either. I'd swear it was the valve train. This bike will not do this until it warms up. I have been to 3 dealers and 2 have said it is normal. If so, why has it gotten progressively louder with (now 2900 miles) on it? The third dealer has said they do hear the noise also but don't know what to do. They had the bike a week and said if I want them to tear it completely down I will have to pay out of pocket even though I have 2 months remaining on my warranty. Any advice? Thanks!
