Alas, not another OIL THREAD!!!!!!!!!!!!
First, what would you EXPECT from adding this stuff to lubricants? What will you gain, beyond the capability of the API service codes and viscosities recommended by the manufacturer?
Regardless, imbibing infomercial Kool-Aid remains an optional beverage; a minority opinion, perhaps, but--don't think additives will hurt anything.
Have seen no Kawasaki cautions against "energy-conserving" or "friction-modifiers," regarding oil. Further, know of no clutch damage to KLRs from lubricity of these joy-juices.
I know, I know; the legend of lasting, permanent and eternal damage from using "non-motorcycle" oils persists, but--ain't seen no examples of it, myself, KLR-wise; nor have I seen any caution from the manufacturer.
Certainly, the lubricity of various lubricants varies, as must consequent clutch engagement characteristics, but--to the point of, "This clutch will self-destruct in 60 seconds," I doubt it.
You want to use this stuff, your call! Let us know what tangible performance gains you experience, their magnitude and how measured. And, don't forget the autographs, as you break the World Land Speed Record!
