Haven’t seen a clutch cover like that before? It’s similar to the RoadRacing one, but with D shaped cutouts instead of ovals. https://www.ebay.co.uk/itm/Open-all...272022?hash=item2171174856:g:cA4AAOSwzRpe5eI2
I imported it from the good old US of A a few years ago. Was trying to put it on my 750 with a slave cylinder mounted in the inside of it. Didn’t work too well so just kept the cover.
