Ugh! I’ve been trying to get the caps off my fast 201 so I can do a SOS mod but I can’t. I’ve tried using an Allen wrench but I bent it, I tried using a knife but I didn’t want to break my yoyo and I’ve tried putting a small Allen wrench through the hole in the axle nut to push it out but IT wouldn’t budge! I really need some help.
Google is your friend…
“caps off YYF fast 201”
“remove caps YYF fast 201”
However, I’ve read somewhere that the later models had the caps glued in, but I can’t verify that.
