As promised earlier, here's the chain cases finished and ready for fitting. The picture doesn't show the full quality of Otto's paint here, it really does look wet. Toying with the idea of running a 428 "O" ring chain on the primary, that and Surflex clutch plates will mean there will be no need to put oil in these. Less chance of the occasional drip of perspiration being left on the floor underneath.
Should be a few steps closer by the end of the day so stay tuned.
