The foofoo valve and the valve that causes some oil mix are two different ones. The foofoo if in the gearcase cover, the other is in the primary. 77 was first year for a foofoo, previous years had a timed breather setup. It is external for 77 & 78, then internal for 79-on.

There have been a few comments here recently that 60w is too heavy for the clutch, but that it is used in the engine in desert climates. Otherwise 50w in both.

Ironheads older than 1976 have a transfer valve which allows engine oil and transmission to mix to a small extent.
For this reason all oils should be the same.
That oil is 60wt.

In 1977 the transfer valve was eliminated and the transmission venting system was changed.
New oil recommendations were issued for the 1977 and newer models, so follow those recommendations for these machines.
Under no circumstances use 60wt oil in a 1979 transmission.

Default In older IHs, plug/weld the valve shut & run Formula Plus...

...trans/primary fluid from H-D instead of motor oil.
You'll notice a HUGE difference in ease of engagement and a more positive feel at the lever.
Motor oil in the primary was adequate back when there was nothing else.

Between the Formula Plus, a Tamer II, and Machinist Mike's HydroClutch kit I now have a true two-finger clutch on my '74 that's pure butter.

It's called PROGRESS.

... and do not ever, ever expect all of us to agree. Read all the opinions, get all the tech info you can, then make your own decision.

And just for the record, and to either help you make your decision or perhaps confuse you more.......
I would never remove or block the transfer valve in a 1974 model (the OP is talking about a 1979 or newer model?) nor would I ever use anything but engine oil in a 1974 myself.

On a 1979 or newer I might use ATF but a better choice in my view is to use Harley Transmission lube.

I tend to think "what worked then, should work now".
Stick to what the old ID's are use to
Sure, time change, advancements in lubes and oils... but, sometimes adding any modern lubes/oils may make them run better but may also have some unwanted side-affects later on.
IMO

Why do you mention a 1974? What is special about a 1974?
