R1200GS 2011 I have ongoing issue from 600 to now 18000 miles with engine running rough and "knocking", motor running ideal while riding in rain for a long time or in hot and very humid areas. In cold and dry conditions it gets disgusting, lacks power, runs hotter, back fires. Multiple check ups at different dealers resulted in "throttle bodies out of sync" fix, and replacement of the Idle Control Device later on. Motor is still rough nothing changed in its behavior. My best guess is a very lean mixture. Is there any digital representation and standards in what is acceptable vibrations and what's considered to be not normal? Any ways to measure that? Is any one know a fix to this issue except for possibly using Power Commander type of device or flashing ECU?
