Title: A50 Speedo Cable Routing
Post by: Andy Edwards on 21 Aug, 2022, 21:01
Hello.  Ref my 1962 A50.

The routing of the speedo cable on my bike just doesn't look right. The gearbox drive directs the cable straight to the off side exhaust down pipe mounting bracket. This causes the cable outer to be damaged by heat and abrasion. The cable was originally routed over the bracket but I have rerouted it below the bracket as it looks as though this is where it should go. I have wound some exhaust wrap around the cable where it fouls the exhaust bracket but this looks untidy.

Does anyone have an illustration to confirm the correct cable routing? I'm thinking of getting a new cable and running it through a length of Firesleeve where it rubs against the exhaust bracket.

You might take a look at the A65 for sale on this site, that will give you an idea but whether that is correct for the purists I have no idea.

Thanks Mike. One of those photos is particularly helpful, it shows the cable routed the same way as on my bike, it also confirms that my cable is too long! I'll replace the cable and persevere with efforts to protect it from heat and abrasion.

thanks again.

According to the parts book, the speedo cable should 67-9063 and 41" long. Worth checking the length of the current cable.
