'77 CB550F master cylinder size
« on: June 29, 2018, 01:33:09 PM »
Hi all,

I'm well on my way to getting my bike road ready before too long. I would like to know what size the stock MC is? So far I've read very conflicting arguments on this and have been given some info from the tech guys at Revival stating that it is a 10MM; however, I've read anything from 14mm to 12mm. Once and for all, what is the stock setup for this bike? Thank you.
If I've learned anything about building a motorcycle, it's check and re-check your work before you put it all back together. Although you do gain more experience by doing it twice.

Awesome thanks for clarifying that. I’ve ordered the correct parts.
