I have a 2004/05 ZX10R. The bike speedo was operated by a sensor mounted over the sprocket.

I am using the original speedo guage.

I now have the prop adaptor fitted and a speedo healer v4 wired in ready.

Does anyone know many magnets will i need to fit to the prop adaptor and what setting should I make on the speedo healer?

I am running freelander diff [3.22:1] and 13' wheels with 205/80/R13 tyres fitted.

Mmmm... not much response there then,

For others, I received an e-mail from Norbert at healtech [speedohealers]. He tells me that the sensor "read" the teeth on the sprocket so no magnets are required. I should mount the sensor to pick up any bolt heads on the final drive. I try mounting the sensor to see if it reads the bolt heads on the prop adaptor.

I'll post how I get on.
