I saw a couple of posts about CB900s on here and it reminded me of something I saw when I was racing in WERA vintage.
There was a guy who was racing a CB900 and kept building hotter and hotter engines for them. He was an excellent rider and didn't all of that power, but it was something he liked doing. The last time I raced against him he DNF'd with a broken connect rod. I took this pic in the pits after the race. The outlined area (A) is where the broken rod sawed completely through the case and the bottom of the cylinder. The outlined area (B) is the only material still connecting the end of the case with the rest of the motor:
