Is the tach a “400t” or a 400 Four? The ratio for a CB400F is 20:3 while the 750 is 4:1.

FYI   - 7:1 ratio on Hondas up to a 550 and the 750's are 4:1   . On the fence about using just the stock tach or going with the Cognito Moto   Speedo and Tach gauge ( GPS speedo also ) $$. I love their stuff , expensive but worth it and their customer service is 2nd to none.

Thanks again David for the info.
