Default Oil change question ...

So I just did a service on my 2015 fatbob, I filled it with 3 qts took it for a 10 min ride and somehow it's past the full point by quite a bit ... Anyone else have this issue ? I expected it to take closer to 3.5 qts

My 2012 HD Service Manual say 2.5 qts for a "wet" refill. Can't imagine your 2015 being any different.

Drain some. It should only be 2-2.5 qrt during a wet oil change. 3qt is way too much.

I also recommend when you fill...fill it up closer to the low level. Once the oil warms up, it'll move up the stick.

I just drained some out ... I probably should have asked before hand ... I changed the oil filter and really the engine only takes 2.5 qts ... What's the primary take ?

32 oz "wet".

Better yet, with the bike level(like on a lift), the oil should just touch the bottom of the clutch basket - the part just outside the clutch plates.

With the bike level fill to the bottom of the clutch diaphragm spring.

Remember the top line is full hot, it will rise quite a bit from cold to hot.

as stated about 2.5qt is all it takes. I also "wet out" my oil filter before installation, which takes a shade more.

your COLD oil fill mark should only be HALF way up to full on the dipstick. starting with the oil level at full then riding and heating up the oil... course its going to be more than full, stuff expands when it's much hotter than the ambient temperature. I'd bet your crank case breathers are spewing oil too.
