| Slipper clutches have a different build order to the normal clutches so whats in most manuals doesn't apply
Can't see why the two steel plates are together, not good for a slipper clutch, can't tell which order they came out in, did the two steels come out first or last.
as for convex plates, not having one isn't going to help and in the ones I use on track I usually use two, although I have known some racers to use a total of 4 convex plates
Getting the end gap right is also important
