Two questions on the speedo drives for the Zeds.
Firstly are there different sizes between spoked and mag wheels ? I have two and there seems to be avery slight size difference and one of the drive tabs will engage whereas the other one won't. I thought they would be universal. The one that was working has a tight spot which grabbed and broke the speedo cable.
This leads on to the second question, has anyone rebuilt the internals and are the parts easy to get ?

Cheers

Speedo drive on my Z1000A2, fits both wire and mag front wheels. Same Kawasaki part number (41078-008) for Z1000A1, A2, A3 and Z1000B1, B2, B4,

There are different speedo drives for 18 and 19 inch front wheels.

Part diagram shows a small pin which would need to come out. Do not know how easy it is to remove, as I have never had to take one apart.
