Any experience with this kind of problem?
I did this a week ago for a CMS that had previously generated unsatisfactory titles. We're talking about 120 or so pages. I made them all shorter.
Google is being very slow about indexing them, I would say so far only about 20% seem to have been reindexed, but when the new title shows up in the SERPs the effect is 100% increased rankings. I did notice as well that among the ten or so I'm tracking, some completely disappeared for a few days. But then they came back.
I don't believe a title change alone could be harmful.
