i got my DM II a couple of months ago, and i switched the Speed Bearing supplied, when i pulled the original bearing off it went BOOM! and sparks flew everywhere, and the bearing blew into bits haha 
it doesn’t have seemed to affect the yoyo, it plays beautifully,
this ever happened to anybody else, with any YoYo?

More than likely just a bad bearing from the get go. It’s happened but no sparks. Never happened on a YYJ though. YYF DV888 and a One drop P1.
No, sorry that’s never happened to me. But that small bearing IS hard to get out 
But as stated above, you probably just had a defective bearing.
how?
So what were you using to remove the bearing, a jack hammer ???
Naw he used gunpowder. I have trouble keeping my bearing on. Mine is black. What color is yours Micheal
a jackhammer? haha, no, just a small pair of pliers, just a pain to get out, really wedged in good, then just boom!
and if you mean what colour is my DM II, i got a red one!
my dm2 is black and my bearings fall off if i’m not careful when its not screwed together.
