or
You should have known better than to leave a bike unattended.
Which of them is proper and acceptable to you?
Thank you.
I understand that "You should have known better than to have left a bike unattended" is equivalent to "You ought to have known better than to have left a bike unattended".

They mean roughly the same in the context of the person having left his bike unattended, which is signaled by the "You should have known better" clause.

Both are acceptable. I prefer the second one because the first one uses the present perfect twice (which seems unnecessary).
