Any oil used with a wet clutch should be rated for it.
Any of the synthetics should carry that rating but why would one put Wal-Mart crap in a bike worth 10-25 thousand dollars.
$14.99 for a quart of Amsoil is cheap if you consider how much per mile it actually boils down to.
An Amsoil replacement in all three holes is only $75 bucks.
The dealer gets $390.00 and uses their Syn3 garbage.
Do the math and don't skimp quality to save 2 dollars.

Do you really think there is much difference, if any at all, between brands? Look at racing teams if you need proof. Do ALL teams use the same brand in their racing engines? Nope. Use whatever company is paying for sponsership and supplying free oil.
If there truly was a "best" motor oil every racing team would be using the same stuff. They don't. Think about this. NASCAR Engines run at 8-9 THOUSAND RPMS for 500 miles and no common motor oil is used between the teams. This is all you need to know.
Change every 2500-3000 miles and it does not matter one bit what oil you choose to use.

HD Formula + for the primary.
Amsoil 20/50 for the crank for the time being. Will switch to M1 VT next time.
The top end is noisy with the Amsoil.
Spectro HD Platnium 6 speed for the tranny. It is 75/140 and shifts smooth....

Marketing folks love guys like you. No offense, but there are only a few producers of motor oil. I know for a fact that KMart brand used to be produced by Quaker State. Only differnece was the bottle it was sold in. Not sure if this is still true today as contracts expire and new deals are made. Amsoil is severly overpriced and is not better than Moble 1 Syn or whatever is out there.

re:Back in the day the primary chain was lubed with the same oil that ran through the engine. A oil line ran into the back of the inner primary onto the chain and then that oil was scavanged back into the oil tank to run though the engine/primary endlessly or until the engine wore out. Which ever came first.
I always wondered what HD engineer came up with that idea?
Seems to me I remember the oil was allowed to drip out of the primary on my "47 Knuckle giving rise to the "oil leaker" tag that Harleys had. How was the oil scavanged back?
Not trying to hijack just curious
