Go kart speedo and tach help ?

[HaM551]

Hi guys, I recently purchased a new kart, I'm now looking at finding a good cheap tach and speedo setup for it, I have been thinking of just a bike one but most don't go fast enough (it's racing kart 100 plus Kph) and no tach. The ones they sell for go karts are $200 plus.

Would a motorcycle one do ? I would have to re calibrate it for the tyre size won't I ? Is this easy ? (Obviously dependent on what one you have.)

Do you know any good cheap setups for sale online ?

Any help / info would be very helpful

Thanks, but will a bike one like that be able to hit 10,000 rpm plus ?
