**UPDATE Nov. 6, 2022** - I've had many questions about excessive ticking noise coming from one or both cylinders. Please carefully check the camshaft lobes for excessive wear, there is a video and service bulletin addressing this issue (due to over-hardened rocker arms). Video: • BMW R1200 GSA Cam and ... . and service bulletin: www.google.com/url?sa=t&rct=j...
=============================
This is a detailed video instruction on checking the valve clearances and shim change on both cylinders on a 2016 BMW R1200GS boxer engine. We show every step from removing the engine guards, valve cover, checking clearances with feeler gauges, calculating new shim thickness, removing the camshafts and shims, and re-assembly showing all torque values and other insights all along the way.
Video markers:

2:01 Remove left engine guard
3:00 Remove ignition coil covers
3:30 Remove ignition coil and spark plug
4:23 Remove left cylinder valve cover
5:16 Remove engine access plug
5:27 Put left cylinder at top dead center process
7:01 Check valve clearances
9:10 How to calculate new shim size if clearance out of spec
9:49 Marking camshaft gears
10:30 Remove cam tensioner
10:55 Remove camshaft holder and camshafts
13:02 Remove and measure shims
14:04 Finish new shim calculations
15:26 Re-assemble shims, camshafts, cam tensioner, valve cover
19:00 Repeat on right cylinder
23:04 Install spark plugs and ignition coils
23:50 Start engine
24:11 Re-assemble ignition coil covers and engine guards on both sides

----------------------------------
Tools needed:
Socket wrench
Torque wrench (10-55nm)
Torx bits: T25, T30, T40, T50
Allen wrench bits: H5*, H8 (* if you have the Touratech engine guard brace)
Sockets: 14mm (deep for spark plug) & 17mm
Feeler gauges: between 0.07mm to 0.5mm
Caliper or micrometer
Small screwdriver
Small long nose pliers

Wire cutter
Straight edge
Wire brush
Small brush (for applying fresh oil during re-assembly)
Marker/pen (I use Craft Smart - oil based paint pen)
Rubber mallet
--------------------------------
Parts and supplies needed for this job:
Loctite 243
Wire ties
Dielectric grease
--------------------------------
Parts that might be needed depending on condition:
Shims (TBD based on your clearance check, if out of tolerance)
Engine access plug washer (PN 07119963252)
Seal kit, cylinder head cover, right (PN 11128542058)
Seal kit, cylinder head cover, left (PN 11128542057)
O-ring - behind camshaft holder (PN 07119907874)
Washer for Cam tensioner body (PN 07119963342)
--------------------------------
Cam Timing tools (not needed, just for reference):
Locating pin to lock crank at TDC (PN 83302327790)
Camshaft end alignment tool (PN 83302327796)
Cam tensioning tool (PN 83300444292)
--------------------------------
Torque values
* Torque values were taken from the Clymer manual and checked against other online sources
Camshaft cover bolts - Torx T30 = 10nm/7.4ft-lbf
Spark plug - 14mm deep socket = 12nm/8.9ft-lbf
Valve cover bolts - Torx T50 = 10nm/7.4ft-lbf
Chain tensioner body - 17mm socket = 32nm/23.6ft-lbf
Engine case access plug - Allen H8 = 30nm/22.1ft-lbf
Ignition coil cover screws - Torx T25 = 5nm/3.7ft-lbf
Fairing screw to access ignition coil cover - Torx T25 Hand tight
Engine guard, front top - Torx T40 = 19nm/14ft-lbf
Engine guard, front lower - Torx T40 = 19nm/14ft-lbf
Engine guard, mate to upper guard - Torx T40 = 19nm/14ft-lbf (w/Loctite 243)
Engine guard, rear lower - Torx T50 = 55nm/40.6ft-lbf (w/Loctite 243)
