Rotella Dino 15w-40. You can run any oil that carries the JASO M2 stamp. That spec means it's wet clutch safe. All the rotella lines of oil are JASO rated,as are the very expensive v-twin oils. Considering it's application I find no reason to put a high dollar lubricant in the primary when an inexpensive one will do. Save the expensive stuff for the engine

Nope - gear lube for the gear box, motor oil du jour in the other two holes.

Amsoil 20/50 in the engine
Spectro Platinum 6 spd in the tranny
Redline synthetic in primary

so far this is the best combo I have found for lower engine temp and smooth shifting

+1 with Rick. I used the same mixture for my ride and all is smooth.
