Wet-sumping got me in a heap of trouble just before I left N-V. After I'd given my notice that I was emigrating to the US, I took my wife up to her folks' place in Lancashire on the back seat of the 650SS "hack" I rode. I hadn't used it for a while, and when I checked the oil before we left, the tank was nearly empty, so I filled it.
When we got to her folks' place, about 120 miles away, she got off the back seat and found one of her shoes completely soaked with oil. I wasn't the most popular guy on the block! I realised later that the engine had "wet-sumped" and probably had a full tank of oil sitting inside the engine.
Unfortunately, I had a gasket failure at the oil line connection to the crankcase on the way back to Wolverhampton after the weekend, and the trusty 650SS seized up on the freeway. It went back to the plant in a van. I don't know what happened to the old girl as we were on an airplane to Seattle a few days later. In retrospect, I wish I'd been able to bring that bike to the US. Sure, it rattled your fillings a bit, but it was a very dependable performer. Maybe it was as well that I didn't, as I found the transition to driving on the opposite side of the street to be difficult, for the first couple of months. Driving a car, you had the additional cue of sitting on the other side. On a bike, you didn't.
