B300 extra speedo cable and dynamo

Post by Todd » Sat Sep 25, 2021 8:03 pm

I am looking for speedo cable suitable for 1954 B300 extra, these are very long approx 1500mm because they are driven from rear wheel , old British bikes are long also but don’t use metric fittings any help appreciated
Another topic, field windings on my generator are 2 ohms , does anyone know if this is correct? Apparently these have max output of 45watts at 6 volts, I have purchased a generic electronic regulator but instructions say field windings need to be higher than 2.5 ohms , so not sure if my windings ok ?
Also wondering if Gilera 150 windings might fit as the look very similar and are available
Thanks for any info
