Old thread. But I used Mobil 1 4XT 10-40 the last time I changed and wow what a nice change. I was using Trick Shift and thought it was good but the 4XT is actually designed for wet clutches. Really good stuff for the primary.

 

Holy thread resurrection Batman!

 

Ay carumba!

There's only one answer that makes any sense: Red Line, and Red Line ONLY.

Don't be fooled by that other snake oil. Red Line is the bomb, can't go wrong, smoke a bong, eye the thong, spank the dong, go out long, eat David Fong, bang a gong, pass it long, sing that song, and read Erica Jong.

Thanks for listening.

 

I use Amsoil 20W50 syn for everything on my softail and my wife's sportster. Makes changing much simpler and I can buy the big jugs.

 

hmmmm, I wonder how many times he has changed his primary oil in the last 4 years?
