The online parts list doesn't seem to receive much, so I thought I might put it here, at least temporarily.
I have used this source for braided lines.
https://www.technafitstore.com/Motorcycles-s/41044.htmI got lines for a 84 vf700c and they are excellent, and significantly cheaper than many other sources.
The site does not have an entry for any of the CBs, but they make custom lines, without additional cost. You are able to choose the clocking and angles on the banjos, even.
And if you goof the clocking, the banjos can be adjusted. Years back on my 78, I got helusa lines. When I replace that line, I'll be using techna-fit for sure.
Just thought it couldn't hurt to let people know.
