I got a new reXtreme 2 today an I was wondering how to get its caps out so I can put in lateral caps. Thanks! 
The usual go with YYJ caps is to attach a suction cup to the caps and pull.

I tried that and they still won’t come out…
If you don’t want to use the caps ever again, stab it each cap with a knife and, once the cap is punctured, use that as leverage to pull it out
Hmm., I’m just really annoyed that it came with a crack in the plastic.
If it was damaged when it arrived, shoot an email to YYJ or YYE. They’ll fix you right up.
