Where are you able to get the PULL throttle cable for these bikes? I'm only able to find the PUSH throttle cable and now have two of them. Everywhere I have found shows the PULL cable discontinued. Will a cable off of a more modern CBR600 fit?

 

As long as it has the correct ends and the correct length, yes. On my old CBR I switched to goldwing cables from the same years for the throttle and choke since I had VFR bars on it.
