Just a note. Clutch gap and end play are two different things.
By definition, end play should be most mininum (about 0.1 mm or so) and clutch gap should be about 0.3 to 0.7 mm. Bigger gap for more agressive engagement and small gap for smoother engagement.
Refer to Glenn Cauley's article on mytsn on how to set the Centax 1 clutch properly.
