12k service?

I did the first 12k and plugs looking great and valves were great and not again till 48k with same results

I don't know anyone who's shim valves on these engines with 100,000 miles

But I do change fluid every 6k

It is not necessary but if you want to keep the warranty intact you gotta play by the rules.

I'm pretty sure they would have to prove that you not doing the maintenance caused an issue. If they can't they are sol

Pretty sure the onus would be on you to prove lack of scheduled maintenance did not cause the issue.

Magnuson-Moss Warranty Act (MMWA) | Auto Care. I don't mind doing maintenance but spark plugs at 12k with a valve check come on

Skip maintenance and you give the dealer/manufacturer an out if there is a warranty claim. Again the onus would be on you to prove your lack or disregard of maintenance was not the cause of the issue. Proving this may well be more more costly than the actual maintenance.

Do what you want but don’t complain if you do not do the scheduled maintenance and are denied warranty if needed.

Checking the valves is super easy on the boxer engine. Satisfying, even. And if the plugs look good, which they likely will, you can always save them and use them well after the warranty has expired. I keep a set but only as a backup, not with the intention of swapping them in if I can get new ones instead.

In any case, DIY maintenance is inexpensive, so I don’t mind buying the correct parts and following the schedule.

Valve check adjust on an Air/Oil/Hexhead are a lot more simple than a Cam/waterhead.

The OP is talking about a 2023. While not hard to check if need adjustment is a bit more complex.

First one at 12,000 is good for peace of mind and establishing a baseline. My 17 GSA has 79,000 miles and valves are where they were at 12,000. I now do service (air filter, plugs, and valves) at 18,000 mile interval. I use iridium plugs and they are ready for replacement then.
Now my 2021 R1250RT is on the same schedule but at 12,000 miles I had to change 6 of the 8 shims. 2 were just out of range and other 4 were at max limit. Now at 37,000 miles and no valve gap changes.
If you have the BMWMOA Anonymous App wouldn't hurt to see who is near you and may be able to help you do the checks.

Right but if it’s as easy to check as on the older models and it’s fine you have peace of mind for the next 12k miles. And if it’s not then well, you do what you have to do and it’s good you didn’t skip it. Can still bring it to the dealer at that point if the shim thing seems overwhelming.

Actually, my dealer told me that the bike would "squeal" on me to BMW (via its CPU) if I missed a required service. It would only come into play if I had a warranty issue, and BMW could point at the missed service and choose to not cover it. This is also true in the automotive world. All that digital wonderstuff we have now is taking notes and can be accessed.

My experience is it’s good to check valve clearances early on. If they are out and you get them in spec, they typically never get out of spec again. If they are in, they typically stay. In other words, if they are ever out of spec, it’s most likely at the first check. It’s pretty easy on these bikes to check them. I had a 90° Japanese v-twin and I had to take the gas tank off, drain the coolant, remove my engine guards, and remove a ton of fidly plastic just to get at the valve covers. On the horizontally opposed BMW engines they just stick out and are right there - so no excuse on skipping the valve check IMO.
