hadnt read this properly, of course 4+5 should be there, that'll give enough room for springs to jump out of place. I think I have a spare assembly at work
***Tip***
If like me you re-use good gaskets, take a lot of care with the kickstart return spring when removing/replacing the clutch cover...It easily jumps out of its locating hole in the crankcase and tears the gasket on its travels
