I've just checked the cam timing on my 40,000 mile 2015 1200. I borrowed all the tools required from the BMW Club UK.
Both sides were out. The go/no go gauge is a very good fit and it wouldn't even try to go onto both cams.
I reset both sides with the cam chain tensioning tool in place, this simulates the spring force on the tensioner plus the hydraulic force when the engine is running.
On replacing the tensioning tool with the original tensioner the go/no go gauge wouldn't fit. So the tensioning tool does make a difference.
I also checked the valve clearances at just over 3 hours since the engine was hot. They were all in spec. I'll check again in a couple of hours and report back on any changes.
I'm out on the bike tomorrow and I'll be interested to see how she runs. New plugs and air filter are being fitted as well as oils and filter.
