Took it out for a little ride today and checked it again when I got back, same thing about 11oz.
Yes engine is all S&S, there are 2 plugs, looks to me like I want the one on left, the right one looks like maybe for cam chest.
The oil pump is stock, I think part number 31-6503, looks like its integrated into the cam plate? Never been apart so only guessing because they gave me an instruction pamphlet for installation. Says S&S oil pump for T-series engines and twin cam 88 engines.

The one the the right is for sump passage to the oil pump. It's the one that most guys use on stock TC cases. They drain less than the oil pickup on the SnS cases. On SnS they drain about the same as the pickup is lower on SnS cases. I wouldn't mess with it.
You have the gear driven cam plate oil pump.. That should be pretty robust as far as sumping goes. Sump oil pump O ring could possibly be damaged tho. With that pump, a sumped motor would recover quickly at idle.
A 124 will have more compression braking than a mild built smaller motor for sure.

Well I called S&S to see what they said about the amount of oil and he said that was over what they should be, he was saying from 3 to 6oz
He said if I were to try to fix it that the warranty would be void, so I need to find a dealer to take it too. anyone know a good shop in MN

Not sure I understand what you are saying here? Don't use the Right plug? or the right plug would be what a stock engine drains? and the left plug would probably drain more?

Ok so I called S&S back to make sure I was draining the right drain plug and now this guy said for the S&S twin cam engine, it is normal to drain 8-10oz of oil from the crankcase. So I guess just flip a coin on it? lol.

If the motor is not running hot and the dyno numbers are where they should be, leave it alone.

The drain plug that should be removed to measure is this one on the left side of the motor sitting on the bike.. The other is the sump scavenge passage. It is what guys use on stock HD TC cases to check sumping because they don't have a center case drain like SnS. On Stock TC Cases you will get a different amount than SnS cases. This was taken with a mirror so it's flipped vertically in the picture.. Use case bolt side case as a reference. It's the left side of the motor. The left side plug will have an O ring and magnet in it. The right side one is a pipe plug.

If the only motor you were used to was the stock 88ci TC motor, the 124 is going to have way more compression braking.
