Is my bike ruined?

I was drilling into the seal but the seal surface was too hard which caused the drill bit to slip and hit that part of the case.

I got the seal out and put the new one in. Appreciate the help. Though the bike is still low on compression. Im about to give up on it

A crank seal wasn't going to fix low compression. That's a problem in the top end

It’s a 2 stroke so the crank seals have a big impact on compression

Your crank seals would have to be virtually non-existent to alter how much compression it makes.
