Cam chain tensioners

Hi everyone first time user...just picked up an 02 vfr800, love the bike. When it warms up at idle it rattles, and I believe it to be the apparently very common cam chain tensioners (I have just over 30k miles, which is when the factory ones seem to go). I know this has been discussed a lot, but before I start tearing it apart I want to make sure I know what I'm doing. So a couple questions: do you have to replace both tensioners at the same time, and what are the manual tensioners/are they any good, or should I just go with regular ones? Any information you guys have would be great.

Thanks

 

Yes, just get the Honda ones and the gasket then forget about it for another 36,000 miles..

 

Manual tensioners are only good if set properly ,fit honda auto ccts .
Or swap it for a 5th gen and listen to the whine.
