That's a .003" feeler gauge.

Is this a typical place for a gen 3 to crack?

I only ride sand dunes, don't jump much or high, and have only had minor spills, if you can just grab the clutch, pick the bike up, jump on and go, shouldn't even be called a spill in my book

I'm gonna go way out on a limb here and guess the previous owners rode it hard. I've had the bike for a few years now, and the crack just recently showed up.
Just thought I'd share.
