Duncan FHZ

Are duncan fhz prone to extreme vibe? Iknow its not my throw because when i do it with another yoyo it doesnt vibe. Could it be the axle or something else? Also, has anyone figured out how to keep the caps from spinning. Thanks for the help.

It shouldn’t vibe that badly.

Sounds like the caps are loose and the yo-yo needs to be tuned. What you can do to fix the caps it this. Take the cap(s) off that are spinning. Then put a little dab of finger nail polish on the place where the caps sit. Let that dry overnight then put the caps back in.

Is there other ways to tune my FHZ? Or is that just it?

That wasn’t an instruction on how to tune your FHZ at all. That was a solution to the problem of your caps spinning on the yo-yo.

To tune a FHZ all you need to do is this:

1)Take off the cap on the bolt side

  1. Then, throw the yo-yo and gently touch your finger to it. How much does it vibe after this?

  2. Take the yo-yo apart being careful to not let the bolt come out of its seat.

  3. Notice how these hexagons line up. Imagine the inner red hexagon to be the bolt head and the outer blue hexagon to be the place it sits in the yo-yo.

  1. What you want to do is rotate the bolt one notch clockwise. When you do that the faces of the two hexagons will line up like this:

Does that make sense? Yes? Good.

  1. Screw the yo-yo together.

Repeat steps 2-6 until the yo-yo gets smoother. You will notice there is a point where the yo-yo is pretty smooth then you rotate the bolt one more time and it is less smooth. Stop, and rotate the bolt back to where it was before. That is the smoothest point.
