Oil Change with inline check valve

The times coming where I'll be attempting my first go at changing the oils on my 961. I was thinking about the process and after reading Richards oil change manual i have a question that's probably easily answered by one of you more technically minded folk.
After removing the two banjo's from the oil pump and now having the check valve installed in the return line how is the oil drained from that line and the oil cooler?
Do I need to remove the clamps and the valve ? I don't see how the oil in the cooler can otherwise be drained or does it siphon off through the main tank.
Please treat this with empathy as there's probably a simple answer I don't see.

thanks

Hi Tiedy

When you planning on doing it Im prob not much help but in the same boat as you, I'll be doing my next one myself, I have the check valve too. I'm only an hour away I'd like to compare to another one as well I'm not sure if mines getting noisier or not. I can ride down most weekends if it works for you and if your interested.
