Chain Replacement

[oneyunguy]

Hi there,

Can anyone provide me with some feedback on some good o-ring chains they have purchased and used? Im a little lost when it comes to buying a good quality o-ring chain for my GZ. I will be replacing with like-original parts. Of course I also have to change at the very least the front sprocket, believe me, I do. Should I change the rear one as well, or can i get away with it if the teeth aren't hooked yet?

What is the pitch I would need and link #?
BTW: I'd be purchasing the parts from either Bike Bandit, or Ron Ayers.

thanks all!
