Inner valve covers installed

Installed the rotary valve inner covers yesterday evening. I used the thinnest gaskets (0.1mm) on the rear cylinders (where I had seen wear on the disk), and the thicker gaskets (0.2mm) on the front cylinders (no apparent wear). I tested the clearance of a brand new hub and an "old" hub (don't forget old hub has only 2-3 weekends running). Difficult to describe the play, so I made a quick video with an old and new hub comparison - I don't really see any difference.



I also measured the gap between a new disk and the crankcase, and this was consistently 0.3 mms on each different cylinder.
