I've had my FB since 09 and only have about 1100 miles on it. I would have move but haven't been riding as I have an issue that nobody seems to know how to fix. When I ride I have no issues but as I downshift or decel I get this really bad shaking or shuddering that seems to be coming from the engine area, not a vibration, but it shakes the whole bike. To me it seems like the clutch is not grabbing properly. I'm not a motorcycle mechanic and am the 1st to admit I don't know much. I've had it in the dealer and they claim they don't feel it, but it happens every time I ride. The bike didn't do this before and only just started the last few times I rode. I checked the bolts that connect the motor mounts to the frame and they are nice and tight. I just don't know where to look. Any help from anyone would be great.
