Checking and adjusting valve clearances

I checked and adjusted the valves today. I have two different sources for the valve clearances. One says 0.05 - 0.10 mm for both valves, the other 0.08 mm for inlet and 0.13 mm for the outlet. I followed now the looser ones as I have understood that having the clearances too small is worse and too large. Both valves were a little too tight so I used my diamond bench stone I use to sharpen my tools to get a bit off the shims. I also changed the valve seals. They were included in the set of o-rings and other seals I got with my order yesterday. The old ones were hard and very brittle. I first thought they are metal or something but they broke easily. Definitely the time to change the seals.

The package contained lots of seals and I don't quite know where they all belong. Need to figure that one out. One is for the ignition cover, and the one I really wanted is for the camshaft tube flange. Anyways, good that I bought the whole set. I wouldn't have thought about the valve seals otherwise.
