Unless you are a slow reader (not that there's anything wrong with that), you should have no problems. I took the test a couple years ago and I don't recall coming anywhere near the time limit. Some of the questions go very quickly and that helps speed things up.

I have to concur - 135 minutes is more than enough. (I think I used something like 90 minutes myself for the whole exam.) The diagrams and questions aren't quite so complicated that you're really in danger of using the whole limit.
