I recently received an O2 sensor error from GS-911 for my 2013 R1200GSW (liquid-cooled). It was for cylinder 1, but I don't know which side HEX considers to be "cylinder 1"...LEFT or RIGHT?
I have heard that HEX's cylinder convention is opposite to BMW's...is that true?
The official BMW "Data sheet, valve clearance" indicates: "Cylinder left 2" and "Cylinder right 1"
I have asked this question on various BMW/GS forums, and have heard both answers, so I wonder if ANYONE knows for sure? But I'm curious what the opinion is here...thanks for any information.
