Topic: just want to make sure I understand. (drive chain) also now a tire question

[Ayrity]

I have a 76 cb550k, it needs a chain, and I saw I need a 530 width chain, and I think i need a 100 link? What i wanted to know really is, is there anything different between the k and f 550's in chain length? Thanks guys, I searched up and down the forums for an answer.

Edit: also, get a roller chain, and not an o-ring or x chain correct?

530 standard chain, 100 links.  Both K and F 550s. Assuming stock sprockets, of course. 

A 530 chain has a pitch of 5/8" (15.88mm) and a roller width of 3.0/8" (9.52mm).
