Hi, purchased my Zed about 6 weeks ago and loved it immediately, about 2 weeks ago clutch was slipping so decided to get it changed. I ordered an F1 racing stage 2 clutch and lightweight fly. I took the car to the garage on Monday who fit it for me, I received a call saying the clutch pedal was right at the floor and could be a faulty slave cylinder, got the slave from Nissan dealers in leeds and fitted that today, they've now called me back and said that although it is better it's still not right, apparently I have about 1/2 inch free play at top of the clutch pedal and doesn't seem to engage the clutch properly! they're having to strip it back down and check the parts/ fitting again! I'm getting to breaking point with the car over this. Any ideas pleassse??
