Timming belt vibrate

[microgalant]

Hi I was wondering if it is ok that the timming belt of my car to vibrate.
My engine doesn't use the balance shafts anymore.
I've put a new timmingbelt, but I see that the timming vibrate, if I rev the car a little is vibrates more.
Please let me know

Sounds like the timing belt is not tensioned enough. Or maybe the auto tensioner has come out. I would check those before you run the motor anymore and skip some teeth.

The belt is not loose, it has allot of tension on it

Take a video of the vibration. If its truely tensioned correctly, the belt will vibrate only slightly. Not very much at all. Is the belt taught everywhere else besides between the cam gears? Are you gears wobbling?
