Help! I cant get the caps off my fast 201

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”

See this:

However, I’ve read somewhere that the later models had the caps glued in, but I can’t verify that.
