This bike came as a box of bits, I did consider swapping the forks and wheel around but  quickly dismissed that idea. I dismantled the speedo but don't understand how to make it work in the other direction. The spinning magnet obviously induces a magnetic field into the metal dish to make the needle turn .Surely a similar speedo which uses anticlockwise rotation works the same way?

I am restoring a 1980 suzuki ts250er and my problem is that the speedometer only works when driven anticlockwise unfortunately the front wheel driven cable turns clockwise. So is it possible to modify the speedometer to run clockwise? 

Many thanks John.
