speedo and tach conversion to r6

I just bought a new set of r6 forks for my kz650 what should
I do for the speedometer and plus im putting a ninja 1000 motor from 1986 on it too so what shoulsd I do with the tach too?

As far a I know the R6 has the speedo driven from the front sprocket and not off of the front rim. I assume the 1000 engine does not have a mechanical speedo either soo.....some kind of Vapor or similar digital dash that uses a magnetic pickup for the speedo and has an electronic tach input will be your best bet.
