Default Which non-Harley oil for transmission and primary?
Manual says Harley oils, I will not use them.
Best substitute? (Harley doesn't manufacture oils, so they just put their label on some connon oils)

I've been using BelRay in both the trans and primary for years with no problems.

Red line all the way, shock proof for the tranny, v twin in the primary and 20-50 in the engine.

Red Line. Has worked very good for me. Fixes the hard to get it into neutral problem. Shifts very smooth.

But the 90W Redline somehow can get in to those bearings? I've used both Redline V-Twin w/shockproof and Mobil 1 and like both, the Mobil 1 is just easier for me to get here in the backwater...

The fluid really isn’t that "Heavy," as it classifies as a 90W gear oil.
