Well the other day i was out riding and i came down off of a table hard on the throttle and low and behold, the chain snapped and got locked up between the sprocket and the case.
Then i noticed that i was dripping oil, and i thought well crap there goes my left side case. There does appear to be a decent sized hole in the case, so im most likely getting a new one to replace it.
my problem comes from what made the chain snap. It was an oring protaper chain, had about 26 hours on it. One ride day before it snapped, i noticed that it was loose (like 4 fingers between the swingarm and chain behind the end of the guide) so we tightened it up to 3 fingers (again, behind the chain guide. hope that was the correct move) and it didnt seem excessively tight through the stroke at all and got rid of an annoying rattling noise. I just checked the sprocket bolts and they seem pretty tight, so im kinda stumped as to what went wrong here. Any help is appreciated!

Did the chain snap, or is it the chain link that fell off? End of chain looks so nice on the pic..

What do you mean by chain guide?
It doesn't sound like your chain was overtightened, and it doesn't look like the chain snapped. It looks like your master link came apart.
The master link retainer clip closed end has to face the direction of drive. If the master link is on the top chain run, the closed end faces the engine sprocket. If it's on the bottom run, the closed end should face the wheel sprocket. Also, the retainer clip can get worn down during its service life, and if it wears too thin it will lose tension and come off. Not sure if that's what happened in your case, but it's something to be aware of and to keep an eye on
FYI: The chain guide I was speaking of earlier is also the case saver. With it in place damage is reduced with a chain break. Also, chain sure looks to have much more than 26 hours on it.
