    New vibration around 65 to 70 just started on a 92 FXSTC. Any ideas would be appreciated.

    Throttle related?
    Speed related?

    To determine if it is engine / driveline or wheels etc causing it, do the following.

    At the speed it is happening at, pull in the clutch at let the engine idle. If it goes right away, check the top motor mount for a crack, which is very, very common. Also, make sure all engine mount bolts and tranny bolts are tight.

    If it is still there, do what Chuck sez....

    BTW, you can also isolate the problem by slowly raising and lowering the RPM. Feel for changes in vibration and then checking all of the above.

    If you do the suggested items you should narrow it down easily enough.
