Gents,
A new (old) Harley owner. Just got a '98 Heritage. Hard core Amsoil guy but I question the use of Amsoil MC specific oils. The MC oils do not have friction modifiers. The friction modifiers would make the wet clutch burn up. Found this out the hard way about 12-years ago with a new Honda. Yup, ran Amsoil racing oil in an air cooled dirt bike and smoked the clutch in 3-months. Since Harley big twins have isolated clutches why wouldn't we want to run the best oil for high temp low RPM applications such as a diesel oil??
Thanks,
Guys
