1979 CB650 Rotor removeal
« on: March 03, 2025, 03:13:43 AM »
I have a 1979 CB650. I need to remove the Rotor from the crankshaft. Can anyone help with suggestions for removal? The rotor has been there ever since 1979 and is stuck!

If you have any rear axles from other bikes in your parts stash, I'd try those first and maybe one will thread in. Heat, penetrating oil, repeat. Maybe a manual impact.
