1200 valve inspections
Not the shift cam but maybe some peace of mind - I've had four valve inspection performed on my 2018 R1200RT. They've yet to require adjusting. I've kept track of the changes in clearance. All eight valves have become snugger by between .01 and .02 mm over 80,000 km and still well within spec. Thanks to Boxflyer, his videos, and his DIY tools, I'll do the next inspection, and re-shimming if required, myself.

The first 12k service on my RT was performed by a dealer and I cannot confirm what was found, but the 24 k service was done during a Boxflyer Tech Day. Only the L/F intake valve shim was close to the tight end of the limit; still in range, but a new shim was installed to bring the clearance closer to the middle of the range.
I checked the clearances at the 36 k mark and found all were still the same; we documented the valve clearances during the 24 k servcie. Most likely, the dealer found all were within specs and would not have changed anything.

2017 GSA, 49,000 miles when sold; no adjustments needed. Only one valve moved from the value of the first check. Moved 0.01mm
2017GS (Annie’s), 51,000 miles, no adjustment required
2019 R1250GSA, purchased used with 2,046 miles. I checked valves in anticipation of adding a sidecar, checked again at 13,300 miles during winter maintenance, no adjustment required.

Just checked my '17 R1200RS at 49,000 miles and happy to report that they have not changed at all since new. I checked them at 700 miles just to reassure myself and no changes at any time since then.
I also borrowed the cam timing check tools from a friend and can also report that the cam timing is spot on at 49,000 miles.

2017 R1200GSA 77,000 miles and still good. I do my checks at 18,000 miles due to no change every time.
2021 R1250RT Checked at 10,000 miles and replaced 6 of 8 shims. 2 were just out and other 4 were at limit, all were high end. Checked again at 30,000 miles and same as last check. This bike now on 18,000 mile interval too.
Bottom line is you don't know what is going on unless you check. Not difficult to do and worth piece of mind. Boxflyer has a Youtube channel and is a great source of information. One of the few people I would trust to work on my bike and probably the only one more meticulous (anal is a synonym) than me.

One exhaust valve shim replaced at 36K miles 2021 R1250RT.
On topic but a different bike....
I just had the 20k km check done on my Aprilia RSV4. For those who don't know of this bike it's a V4, 200+ hp sport bike. All valves were in spec but at the tighter end of that spec. They were adjusted to the middle of the specification.
Taken in total, I think this thread is telling us that manufacturing design, tolerances and materials are much better than those of the past.
"They sure don't build them like they used to!"

Valve clearance checks
Hi my 2020 RS had the left side checked and adjusted by the dealer at 4k after I complained that it was noisy. At 12k I did a check on both sides and ended up changing 2 shims on the exhaust on the right side left was good.These motors are noisy especially the left side.

I do a lot of service on different bikes. I always recommend checking valves and timing at 10,000km. Turns out all but one out if 15 bikes I have done the timing is out and often the cam position sensor. About half the bikes the valves are ouroff spec and need shim adjustment. Both truly improve how smooth the engine runs and it seems to improve powere, seat if pants assessment.
