Here is a link to an article I wrote several years ago about the Yamaha oil
transfer system. I hope it can help you.

Yes, that does help. I see some references to a filter causing
problems with the sensor inside the main oil tank:

"Carefully remove the unit, making sure the black foam sealing washer
stays with the tubular filter element. If it remains in the tank, the
seal can be forced into the feed hose going to the engine-driven
metering pump which could block the flow of oil."

In taking my sensor out, I didn't see any filter like that. Would
that be something in newer motors?

My sensor is a very simple thing, a cap with a long tube with an end
cap at the bottom secured with a circlip. If you take the circlip off
and the outer tube there is only the float remaining.
