Went over to my brother in law's house, him and one of his buddies were taking the top off when I arrived and had discovered that a chunk of the sleeve had broken off.

Rotate your crank to see how true it is paying close attention when you spin it in the cases . An unbalanced crank will cause the cylinder skirt to break . What is your bore at ? 66.5 or 67mm over bores tend to be fragile and skirt breakers .

I don't remember the size, but it's the largest bore available before needing a new sleeve.

The last bore is a 67 mm which only leaves aprox 1mm on the lower sleeve which IMO isn't enough .

So you're saying that anybody who is boring theirs out to a 67 should just resleeve instead?

[shortline10]

Yes,
I would not recommend a 67mm bore , Much cheaper to buy a used cylinder at stock 65mm and do a 1st over bore .
