Regardless, thanks for sharing your most interesting research.
Oils containing "friction modifiers" or formulated with some "energy-conserving" association may indeed be detrimental to wet clutches; just didn't recall any Kawasaki advice to that effect.
Sorry about your clutch; if it failed as a result of running zinc-laden Mobil 1, this fact's worth a warning to KLR (and other wet-clutch motorcycle) riders.
Again, appreciate the references.
Seems interesting that my Honda manual says it when the clutch technology is basically identical.
Regarding my clutch- I alluded that I couldn't directly attribute the cause. I did use Mobil 1 for many touring miles with medium-duty off-roading. I later switched when my clapped out car dictated cheaper, thicker oil.
