'77 CB750F Tach Ratio?
« on: February 10, 2018, 12:00:49 PM »
Hey guys, I'm looking at putting a new tachometer on my bike, and was wondering what ratio the '77 supersport is. I found a couple places that say the SOHCs are 4:1, but I wanted to check to be sure.

Looking at putting a 4:1 2.5" tach from Cognito Moto:

my google research points to 4:1 as well.  vintagecb750.com has all the Fs from 75-78 showing as 4:1.
