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.
