Yea, hard to believe whos right about what oil is best to use.
I remember in the 70's, I think it was "Cycle World Mag" did an extensive oils test looking for the difference between 10W40, 20W50 and several others of Oil temp, engine temp and head temp.
They're test showed temperatures reaching the edge of destruction with the heavy oils like 20w50 or straight 40W when the bikes were riden hard or high speed cruising. And the only way to cool the engine down was with the "throttle hand". Easy accell and slower speeds.
When the bikes were useing the manufacture suggested 10W40 oil (no brand mentioned as I recall) they stayed within a safe temp range even when driven hard. The only bike not effected was the water cooled.
When the Moto Guzzi race team started using Mobil 1 (synthetic) oil, they noticed much less valve adjustments had to be done between races. So I assume that ment less wear on the engine.
Do you know anyone who'd like to trade a Baghira or Mastiff for a 2002 Skorpion (only 3,700 miles). I got long legs an need more room to stretch out.
