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.
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.
