It doesn`t matter what year the bike is when it comes to the primary lube level, all the same on wet primaries (mid `85 and later).
You must not have seen that when you tried to look up the answer in google so you could come here and make another babbling post.
The manual is often incorrect when it comes to the amount of lube needed (my `89 service manual says fill up to the derby cover opening with bike straight up), that must not be in google either.

Again typically I just dump the amount in from the manual, and don't waste my time checking unless I have a leak or the primary was dry. Yes you can look at where it is on clutch, but you need a starting point.
2016 maybe they went the narrower primary like the lows, takes less. 5 speeds less than 6s. Transmissions keep changing too.

Some are here to disrupt and talk about themselves.
Just click on a name and you can pull up all the previous posts made by a person, that will give you an idea how legitimate that person is.
The fact is primary capacities have changed over the years, but the method to measure the correct level is the same for all big twins with a wet clutch (mid `85 and later).

@ethologicac This is a good example of why you need to be careful about who you listen to on a forum.

Last I checked, (when done on jiffy stand) the primary won’t even hold a full quart without spilling over/out the derby cover hole. I can’t imagine getting double that in…. Did you some how fill while the bike was on a jack or lift with the rear end higher than the front?

I agree. Use that nice graphic Dan posted for you, grab a flashlight and make sure you get it to the right level and everything will work as it should.

Something very wrong if it took more than 32 oz. Drain. And start over. My best clutch and shifting performance was with HD Formula+, And fill as per @Dan89FLSTC . Over filling, even by a little will cause the clutch plates to drag, and hsrd shifting, and hard to find neutral.
And ignore Rounders, he just likes to hear himself talk, regardless of whether be knows what he’s talking about…which is rare.
oh yeah,.make sure it really is the primary that you are draining and filling.
