Hi Beachcomber,
I would answer that with “Yes”.
That seems to be the target when Kawa decided to use that “bell” shaped collector.
I never came accross a filled “bell”. Everytime I remove one, it is more or less clean and dry inside, so there must be a drain opening.
For sure it is possible to route the pipes into an external breather.
A cover, where the bell sits, should be mounted. Otherwise the drain opening may spill out oil and dirt and water will enter the engine.
PS: I’ve never investigated how this stuff works in detail 😉
Cheers, Michael
