Herbies tube damper tightness


How tight should Herbies tube dampers be?  I just tried to put an UltraSonic Rx damper on a 6h30 tube and it was so tight I thought it was going to crush the tube.  Is it normal for them to feel very tight during installation?

If you bought them new, instructions should be there. Open them up so the rings have hardly any deflection.

That's correct. Widen it so little to no deflection when installing. So hardly any tension on the tube. If you go too wide just squeeze them smaller.
