Between idle and 1800 rpm my flhtc vibrates like crazy. I have tried everything I know including a new front engine mount, both Harley and Velva ride, rebuilt the carb, checked for vacuum leaks, checked the compensating nut on crankshaft, checked primary chain tension. I'm at a loss. I'm afraid to take it to the dealer cause they looked at it once and said it ain't too bad. That it's what Harleys do. Any other ideas out there? It didn't do this a year ago. I have the 95 inch big bore and stage I with 70,000 miles on a 2002 model. Other than the irritating vibration it runs strong.
