digital tachometer/speedometer on a 1993 xj600

[FredT]

Hi!

I'm looking for a digital tacho/speedo for my 1993 Xj600. But my bike use an old metal scare wire to link the motor to the tacho/speedo..

Is it possible to find a digital kit using this old technology?

Is exist a "transfer box" for change the old metal scare wire to digital data?

and finally, somebody knows what is the tacho/speedo ratio on a 1993 xj600?

Thanks a lot!
