Yeah, they sure don't make filling it easy do they. And on an angle no less. But the Spanish always seemed to have their own ideas about things. I used to ride Ossa's back in the day and they had a lot of unusual engineering, loved them though ...uh oh, now I'm given away my age The Squeeze bottle seems like a good idea. American GG recommends GM transfer case fluid. At 400cc's does it show in your window when the bike is level?
Thanks again
