Hi,

I recently had an issue with a slack chain and clunky gear changes, so I replaced the chain and sprocket. Just before I had the sprocket and chain replaced the speedometer stopped working.

The light comes on the instrument panel, the rev counter works fine, but the odometer and speedometer just sit idly.

Does anyone know of any simple checks I can do for this? Would replacing the unit be a simple fix?

I had a look for info the Haynes manual and they rated it as a 3* job and specified that calibration and testing of the unit should be done by a Kawasaki dealer.

Any info much appreciated.

Thx

Apologies for my ignorance, but where do I find the cable?

Should I take off instrument panel or side fairings?

thx

Usually on older designed bikes (perhaps like the GPZ), the speedo is driven by a mechanical cable that rotates inside a sleeve. This is usually driven from the front wheel.

Newer bikes however seem to use the front sprocket for measurement, and as such it would be worth checking to see how the GPZ speedo is driven. If it is electrical, the sensor may be on the front sprocket. If it is mechanical then the speedo drive will probably be on the front wheel.

Looking at this image, it seems as though the speedo is cable driven off of the front wheel. You can see the cable curving down from the top fairing to the front wheel hub.

I'd check the connection of your speedo cable if I were you.

goes from the back of the speedo to the hub in the centre of the front wheel

you can reach it without unscrewing the fairing, but i find it much easier to loosen it, pull the fairing forward and there you go.

the cables snap sometimes, just buy a replacement for a tenner from wemoto and screw it in. it helps to use threadlock as they can come undone easily. mine was always falling off until i did this

Thumbs Up

What he said. Check it hasn't just unscrewed itself from the back of the clock before you order a new one.
