Thanks for the reply. I managed to pick up a low KM Z900 clutch assembly from the wreckers. Have ordered some EBC Z1000 springs as genuine Kawasaki are 8 to 12 weeks away here. They are supposedly a heavier spring so hope that doesnt stop the slipper function from working. Z900 springs are a different P/N and are supposedly a softer shorter spring.Yes, it will work on any z1000 that is 2010 or newer.
As far as what plates you need, order everything that's on the list and you'll have what you need.
An easier and cheaper way if doing this is to watch ebay and find a complete clutch for a Versus 1000, 2017 or newer ninja 1000, or a z900/900rs.
A clutch assembly from any of those bikes works. Yo can recognize the correct part by seeing the 3 springs and not the 5 springs the older bike has.
Do the later Z1000 clutches have 2 different plates fitted. The one I have got has 2 plates, 1st and last with larger / normal size friction pads and the rest have more smaller pads. Have not seen or found any mention of this on any of the forums or videos. Parts diagrams show the same part number between the 2 engines.
