I been through this debate too. 3.7 to 4.0.
It does not matter!!!! The difference is in what the sight glass is telling you. It is .85 of a quart difference from the bottom of the glass to the top of the glass, period.
I am not debating it, just stating fact from two manuals, and my dealer.
In both manuals it stated they USE to specify checking on the side stand, however in my manuals it says to NOT check it that way and check it as I described.
Your bike you run it how you feel comfortable.
And yes I did measure 3.7 with the change I did as well as measure the FD and Tranny Amsoil Sever Gear.
I was afraid that the .3 of a quart would help contribute to side stand smoke outs. I was told not so, and not to worry about it.
At that time I pointed out that we purposely ran our Twin Cams a bit low to keep it puking from the air cleaner. While not the same engine I wondered if it would help on the SSSO (Side Stand Smoke Out), and again I was told no.
I was also told do you think the dealer is measuring that last .7? Or might he be just dumping 4?
In the greater scheme of things the 3.7-4.0 is not as critical due to the design of the motor, but .85 down on oil would concern me for any distance, and as I said I look for a level well above the center line.
My bike, my care and feeding.
