I havea modded nonresponsive FHZ. But it’s temperamental. Sometimes it’s dead nonresponsive and sometimes I could practically throw 2a with it. What gives?
Go down the list of things to check. Are the walls of the yo-yo smooth? Does the string slip between the bearing and spacer? Does the bearing spin nicely? Have you tried using a different bearing in the FHZ? If so, was it temperamental then?
How is it modded? Sticker or silicone recess? If sticker, is the sticker touching the bearing?
Thanks for the tips guys. I’ll check it out.
