re-calibrating a bike speedo

[Darkcat]

Morning all, A quick one (to which i think i know the answer)

I'm starting, well re-starting, a bike engine'ed mini project, and want to use the bike's loom and electrics in the car, as we all know mini's have exceptionally crap wiring.

I want to use the bike binnacle as the main instrument display, as it has all the correct tell-tale lights and dials needed to pass an IVA test (i think).

Now obviously in sticking this bike engine into the car i am going to be altering the gearing so throwing off the accuracy of the speedo. Are there any ways to actually re-calibrate a speedo, or am i going to have to make up a new segmented face for the dial?

(its a Honda VTR1000 bike, but this wont help at all, as nobody else uses this bike in a BEC format, yet...)

Is it cable driven or electronic?

Speedy Cables can recalibrate a lot of cable driven speedos.

Really easy to fiddle an electronic speedo too with a PIC or AVR etc!

You need a "Speedo healer". Very easy to fit and adjust.

There's also a similar device called "Yellow Box" but it has limited adjustment range.

Perfect thanks guys!

not cheap but should do the job, and slip directly into the bike loom.

Sorry for the slow reply!
