to check it's condition, be very careful to make sure you document how it's parts are put together. I've heard from other riders about getting it out and apart then realizing they didn't pay attention to how it goes together. Apparently there's a mistake that can be made with the short, fat spring.

There's a write-up in the ninja250.org FAQs about cam chain tensioner maintenance. http://faq.ninja250.org/wiki/Cam_cha...er_maintenance

If it's all pitted like this guy's was, I'd say you should replace it immediately. http://forums.ninja250.org/viewtopic...=778906#778906

I've heard that a loose cam chain can tear up the two guides/tensioners that ride against it (this is mentioned near the end of the Cam Chain Maintenance article I linked you to above) They're made of plastic and if this happens you can find the plastic bits on the oil screen when you do an oil change. (here's the oil screen checking article, http://faq.ninja250.org/wiki/Checking_the_oil_screen)

Good luck with it.
