thanks
Because the vendor rep for Spectro flat out stated "Do not use this in wet clutch air cooled engines"...? Asked him when I was still in the business specifically about using ANY Spectro product in my 1998 Savage I rode back then.
I had recently dropped Castrol GTX 20W50 as my preferred oil. He recommended Shell Rotella, Mobil Delvac or Chevron Delo 15w40 for use in, let's be brutally honest, "primitive" metrics.
