Just a update, BMW have now had my bike since 12th May, BMW sent the Dealer modified engine parts and instructional video on how to fit them, They were also instructed to video themselves replacing the parts.
I phoned the dealership last week for a progress update, and was told one of the parts...
Hi
I had this problem with mine at the beginning of may. I had the bike towed to the nearest deal, they had it for a week and said they could find nothing wrong, I told them it only happened after a decent ride out.
so I picked the bike up rode it home and put it in the garage on the side stand...
I've just checked mine by sitting on the bike holding it level then using the video record on my phone and filming the level. then play it back.
not great but it should me the level
