I also note a factual error at least for the R110S: BMW doesn't recommend "mid-grade" - the spec for US bikes is premium 95-RON/85-MON which is generally 91 pump or higher. I had thought that all the R1100/1150's required premium, but perhaps the lower-tune models allow mid-grade.
Please correct me if I am wrong but:
95RON is EU type fuel designation aka regular here and the lowest available. Premium is 98RON.
85MON is US type fuel designation. Given that you can get (from memory) 87MON, 91MON and 93MON, doesn't that mean you can feed the cheapest stuff you can get? I mean, if 85 is required, why feed it 91. It should not ping running 87.

Whatever happened with a wooden stick with a sucktion cup at the end, two hands and a little time? I grinded my own valves when I did an engine overhaul of my old CB650. They prepped the seats with a machine, but I did the final grinding myself. It's a bit of a tedious job and a little time consuming, but like most things you do with your hands it is also very rewarding.

Damn, I am just realizing I am starting to sound like my dad! Must be getting old.
