Timing belt flex?

This may sound like a stupid question, give me a sec to get to it.
I had my timing belt off today when i was wrenching on my car, and was observing the timing belt to make sure everything was in good order. Then i revved up the engine and the belt seemed to flex, or vibrate slightly. Not enough to jump teeth or anything just enough to make me take notice.
I changed the timing belt about 8 or so months ago and then i parked the car in a garage for other repairs for about 8 or 9 months. The car runs better than most new cars i ve seen and the engine barely vibrates during idle, you can barely notice it running for the exception of the timing belt whine.
Now to my question, is this flex normal? I torqued everything to spec and followed a chilton, haynes, and online manual to get the best of all worlds. The car runs great i just have never seen the timing belt in action-should i worry that its not tight enough? Any input would be great

We're guessing you meant you had the cover off.

If your tension is in spec, you should be fine.

Leave that cover on there. Some things aren't meant to be looked at.

yes i did mean the timing belt cover--goofy me. Yeah i guess your right, maybe i should just leave well enough alone. Thats what everyone keeps telling me.
