How does my final drive breathe ?

[unclepete]

Airheads have a breather on top , as do many others .
The new to me 1994 California 1100 does not .
The rear end was overfilled according to my info .
Is 250cc including the Moly correct ?
Thank you .

You are correct, 230 + 20.  It breaths into the swing arm/drive shaft area. I have known oil vapors run up and lube it all. That was the design. In reality it may be dry, gotta look in the boot for U-Joint or all of it. IF you really want to know.
