its an flhtc,thats all i know,i had the cam cover off to replace the gasket ,noticed the large cam gear had 3/4 piece missing from the 3/4 raised circle on its surface,mean anything ??

 

Your engine is not a "B" engine, but rather mounted with rubber mounts.
If you have your cover off, and you willing to go farther, you could check pinion shaft TIR with a 1" dial indicator.

I have a dial ind,will check runout,thanks,that piece that's missing,no big deal??

 

How many miles on the bike? Any recent modifications or repairs? Did the vibration just suddenly start?

Post a picture of the cam sprocket and missing piece. Check front motor mount for cracks; could be broken but if so, I think the vibration would not be limited to a 500 rpm range. Check torque of the motor mount bolt to insure it is up to spec. Do a thorough inspection of all fasteners connecting stuff to the bike; could be a loose or last fastener. Check compensator and chain tension.

Also do some internet research on the procedure to check runout. The motor, being on rubber mounts is subject to movement so securely mounting the dial indicator to the motor is the proper way to do it. You might need to fab up a fixture that can bolt to the motor, via the cam chest, to mount the dial indicator to. Whatever decision you make should be based on accurate measurements.
