Derby cover spring
Hello everyone this is my first post, its also my first harley, ive just updated my 1941 bmw with a 2009 sportster 1200l, anyway i was just removing the derby cover to change the oil in the primary and noticed there wasnt a spring behind there, ive looked inside the primary to make sure it isnt hiding, everywhere on the internet is saying i should have one, what does the spring do?

It keeps the clutch adjustment well nut lock plate (has two flats that hold the clutch adjustment screw stationary) from backing off the well nut.
Number 15 the well nut lock plate, number 5 the well nut.

No need to remove that derby cover just to change gear oil. Just drain from the plug and refill through the chain inspection cover.
From the photo posted, it does not look like that spring could migrate into the clutch/primary chain area without some work. Some PO probably forgot it.

I don't think you need to worry about it being in the primary, it can't get in there with the derby cover installed. The PO probably forgot to put it back on.
What can get in there maybe is the lock plate. It's thin enough to slip into the primary I bet.
What I wonder is, do you even have a lock plate on yours? If the PO forgot to put the spring back on, he may have forgotten the lock plate as well. You probably wouldn't notice it for awhile until the clutch started getting sloppy.
