In the parts box I came across two spacers (clutch) I've bought decades ago, for... just in case. I guess Honda has fitted these on assembly when a clutch showed a degree of play and none when there was no play at all. My own bike came with none and still does not need one. Am I right to assume it has little to do with wear? The smaller one is 0.5mm thick and the larger one 0.1mm. Why the outside diameters are different? No idea. :? By the way, the spacers are mentioned in all CB500/550 parts lists as optional parts either with ( ) or with an 'N'.
