Hi Guys

How long should the inner / outer of the speedo cable be? I took off an obviously too long one ( apparently Mirage cable) and fitted one that was about 80cm long. This seemed perfect, if a little taught, but i get a loud whining sound when i ride. I have recently had the gauges overhauled by MARCEL ( cb750faces) -super job - but when i ride it whines very loudly at the head end. I put the speedo on a drill, it runs fine, i connected the cable without the speedo connected and it turns fine and doesn't make a noise, but when i put them together it whines.

I wonder if the cable is not seating properly in the gauge, but then i wondered if it was too tight and pulling out or unseating as i ride. Its ok up to about 20mph, then it kicks in.

Want to check i have correct cable length before i start messing with the other components.

cheers

check the gear set in the speedo drive on the front wheel, probably needs cleaning and fresh grease, especially  the spindle that drives the cable.
