Hi,
I used 10w40 for the 600m oil change since the dealer was out of 10w30 and recommended 10w40 instead. The last couple of times I took the bike out for a spin in mid 40s temp I noticed louder than usual valve clicking (almost small knocks) sound from bottom front right corner of the engine, I also noticed rough idling and jerkiness (RPM fluctuations) during first few minutes or few miles of riding. Once the engine warmed up it was back to it's normal smooth self. Didn't realize that switching to 10w40 would make such a difference in cold temperatures. I don't plan on riding much longer in colder temperatures and thought I'd share this anyway to see if anyone else has any such experience or input.
Thanks,
