I believe the manual calls for 3.9 quarts.
If you get all the oil out (engine hot, dip stick and oil fill cap and oil filter removed, after left to dripping, you get on the bike and lean it as far over right (over the catch pan) as you can for a minute, it takes 4 quarts. I'll even bump the starter button once at the end (lawn and leaf bag under bike) (don't let it start).
I had an aftermarket Show Chrome dip that was not accurate so got in the habit of checking with OE dip sticks.
Just like I told my VTX buddy. We changed his oil. Put in the exact right amount. So I ask him how you are supposed to check it. He says I don’t know, does it matter. I reply nope doesn’t matter. Check it right now However you like and where the oil hits is correct. He did it on the side stand not screwing it in and the oil was like 1/8” on the stick. So I told him if that’s how you want to check it that’s where the oil should be. You can even scratch a new line on the stick if you want. Just for giggles I put the bike upright and checked it not screwed in and it was perfect on the line.
If you know the oil is right. Where it hits on the stick is irrelevant.
I check my oil every day before I ride. I look under the bike. No oil. It all must be still inside.
