ok so im trying to check the freeplay on my slipper clutch (03 zx6rr), manual says i need a spare driveshaft, i dont have one, any ideas?
im not sure if shops have driveshafts just laying around to check freeplay?(they wouldnt be universal would they?)

some of my steel clutch plates have brown burn marks on the edges only in 3 spots on each plate like a triangle, the burn marks get worse closer to the inside on the clutch then slowly dissapper as the platers get further towards the outside of the clutch, should these be replaced/reversed orrr?

thanks
