I bought a NC30 with km clocks. These had a sticker over it that converts it to MPH. I thought this looks nasty and bought a MPH set of clocks. Tried this and the speed was out. Then went onto weemoto and bought a km-MPH converter, still out. what am i doing wrong here? I just want the MPH clock to give me a correct reading. Is it something i am doing wrong?

You need the convertor with the KMH clocks - it will then read the speed in MPH against the KMH numbers.

Or, you need the right MPH clocks - they all run off the gearbox so it might be that your MPH clocks are KMH clocks with a new dial on them.

I have just left mine to read in KMH...I don't find it a problem at all

thank you for your help, will try this tonight.
