Topic: install CB750 speedo and Tach on a CB500

[rtbmrgl]

Hello,
This is my first post so bare with me, I'm restoring a 1973 CB500 which was a 60th bday present (bought from the original owner with 1243mi),
 My question is can you install a CB750 tach and speedo on a CB500.
The size is not a problem and redline is different on tach and top speed is higher. Are the drive ratios the same. Im having trouble finding a new or almost new CB500 speedo and tach.

thanks,

750 tach has a different ratio. Look for 550 as well as 500.

another question,
the odo reset button is missing, I'll be looking one ebay for another speedo unless I can find pieces,
Do the reset buttons screw in.
I think I will get new faceplates and rebuild these

Some have a set screw in the knob, whereas some are threaded on opposite thread of normal reset direction...

FWIW,
If you put a CB650 cam & tach drive gear in your CB500/CB550 then you can use the CB650 or CB750 tach.
