chinese koso replica rx2n
 

Has anyone fitted these to a vtr. Im having problems with rev counter and speedo not working

Revs are supposed to work off a coil wire if I recall, or its able to wrap around a spark plug wire for the pulse signal.

I rode with it for a short while but then adapted a cbr600 dash
