Yes...
There is a hall effect switch by the chain drive sprocket on the motor...
it is switched every time the magnetic field is interrupted.
its easy to remove the switch, you can trip the switch by passing a metal object (screw driver) past the switch this will interrupt the magnetic field and send signal to speedometer.
it will take forever doing it this way. I used an allen wrench in a dremal tool?(long end in the chuck) hold the short end near the switch and you will see the speedometer start to move, the faster the dremal tool spins the mph increases.
The key on the W has to be in the on position. I had to put on 5000. miles to be able to register a low mileage out of state bike in California. Even with the speedometer showing almost 100mph it took hours to get the mileage i needed. Made a jig to hold spinning tool close to hall effect switch (wood and hose clamp.)
