If you check the "Photo Gallery",  the photos look better. There is another part to replace the shims, if you need it let me know.

thanks
Very nice, so I can work.
I think I'll go to the garage tomorrow.

One very important thing is still missing.
If the valve clearance is not right, you have to take out the camshafts and readjust them correctly later.
In German this is called "Steuerzeiten"
If you still look it up.
To do this, you also have to fix the crankshaft.
I think you find that around chapters
"replace both camshafts"
Thank you very much

If you need to change shim, in my case I did not do it myself but all exhaust needed new shims.

Thank you very much for all the information.
Here in Germany it's winter now, but the last few days are very warm 10-14 degrees.
I went to the garage today and checked my valves.
Valve clearance was OK.
It was found that the chain tensioner is defective.
I need a few days to prepare everything to poast here.
See you

That was fast! How many km's on the bike? One my F2019 GSA, they changed all the exhaust shims. They told me that that they were all very close to the limit and if they change them now, I should be good for a very long time. The valves were checked at 25k km, I'm now at 27,5k km

So, I have reassembled my engine.
Valve clearance was OK.
I would like to share my experience with you.
Here are the tools you need.
1. spark plug spanner 14mm (I only had 16mm)
2. hex key H14
3. torx T60
4. feeler gauge
Otherwise you need the usual tools.
At the very beginning I would like to warn everyone!
The BMW F850GS Repair Manual DVD is faulty in at least one place.
If you fix the crankshaft as described, no piston neither No.1 nor No. 2 is in the TDC at that time!!!
So don't use the old method and put piston No. 1 in TDC!!!

I think everyone is able to remove the side and tank cover and the fuel tank.
I just unscrewed the fuel tank but did not disconnect the fuel lines but put the tank on the frame.
BE CAREFUL WITH THE BATTERY, DANGER OF SHORT CIRCUIT!
Please remove the battery or insulate it really well. Fix the fuel tank really well to the frame

After unscrewing the cap, you can check the valve clearance. Checking is really easy.
Be careful, the 4 screws with arrows have washers that can fall into the spark plug hole  (This is important when removing the camshafts).


To get the crankshaft in the right position, we have to turn it.
To do this, the plastic plug Hex key H14 must be unscrewed so that we can


turn the crankshaft with the Torx T60.


You have to bend the feeler gauge a little bit.


I checked the inlet valves first


For the exhaust valves you have to bend the feeler gauge even more.


Now you can check the exhaust valves


If the valve clearance values are OK, you can screw the cover back on.
How to remove the camshafts and adjust the timing again I will write about separately.

Excellent, thanks for sharing that! FYI @Eddy_G No I have not had any luck with fuel tank & fairing assembly on my bike so i've no idea what to do there. This bike is very new to me mechanically and much more annoying to take apart than my previous BMW tourer.
