I know there's a thread going on this already, I did ask a question or two, but don't want to hi-jack the thread..
01 roadking, vibration started this spring after a new motor mount over the winter. Was very very bad, now just very bad. Lol
Mostly off idle 12-1400 rpms. It was mentioned bad vibs usually mount or flywheels. I've got S&S flywheels, and no previous issues with vibration. So I'm thinking the new mount.
But if it was the flywheel, I have gear drive cams, would I be getting loud or strange noises from the cam chest ?
What type of motor mount did you install. Some aftermarket ones do vibrate more and the Harley -D part is a little stiffer than previous versions but I am told they eventually smooth out. If you fly wheels were out enough to shake the bike I would think your cams gears would let you know quickly. Might check your top motor mount to be sure it is secure.

Not sure who's mount, not one tho.
Bikers choice maybe ???
Will check top mount tho, haven't done that.
Back the ny-lock nut on the bottom of front motor mount way off and see if the vibration is still there.

Haven't tried that, but now I will.
Idle isnt bad I idle at 1050 ~rpm, I do have a tach on the bike. , it's just off idle say 1150- 1500 rpms.

Let us know if you find problem I parked my 12 ultra when I went for first ride next spring when I slowed down felt like I ran over a rumble strip got off checked for a flat. Turned out was bad motor mount , was fine when I parked it , next time was bad. Went bad that fast .

I wonder if Bias-ply tires get flat spots when park all Winter.

Mine do. Not horrible, but my bike definitely has more vibrations first ride of the spring until everything gets up to operating temperature for a while.
...speaking of tires..check air pressure...set them to specs...it can make a world of difference...
