The first package from MuS Förster arrived, he checked the crankshaft and the cylinders. The crankshaft was in very good condition and was only re-balanced, the cylinders unfortunately had to be recoated because of a damage due to loose catalyst parts. I also ordered some small parts like gaskets there.

And the second package has arrived too. After only 5 days delivery time the parcel arrived from www.thetuningworks.co.uk: New CNC milled power valves, also known as Cooper Valves or Cougar Valves. Here the problems of the weak center pins were solved by milling the whole part out of a solid body. Maybe a bit expensive, considering that I don’t want to drive the bike anymore and just put it into my livingroom.
