Zomby, don't take that personally. I have no doubts that you may have way more knowledge about mechanics. My comments are in regards to your initial comment which I took as "smartass"ish. By the way, turning it upside down didn't work for me or the shop I took it to. Also, we both started in this forum at the same month and year so the rookie thing is misunderstood unless you are referring to some sort of historical expertise that you have which I know nothing about but would galdly respect in the future when you provide ME with advice that is useful and not just at my expense.

You can use one of those magnetic extending rods, but not with the swivel head, to fish around, maybe even go in from the side if you have the side covers off. I don't know if there's any sort of bolted on sump plate on the bottom, you may look.
I had the decompression spring come off on my 650. It meandered down into the bottom end getting a bit mangled on the way, but it still ended up down there without any effects on the engine.
Then there is the possibility of your trying to pour kerosene into the bottom end to thin the remaining oil so it won't stick somewhere, I'd carefully dump it in the filler so as to not disturb the general location of the ring. Then try the magnet again down in around the crank. I remember they used to use kerosene to fill the crank cases on two strokes when pistons fragged, to get the fragments out. But that was done with the engine out of the frame. Too many places for the ring to get caught with the design of most four stroke engines since they don't need the "shrink fit" crank area a two stroke did.
I'm not sure the path of the oil from crank to gear box, that would be my only concern. I don't think that ring could affect anything with the crank since it certainly won't float. I'd be more concerned if it could somehow end up over in the clutch/gear box area from a tip over. I think it could be bad news if it got caught in gears meshing, but I don't know. If it was a separate gear box/clutch like a Harley I'd not bother. It would just lay in the bottom of the engine for ever. We found junk like that in car engine/transmission pans before.
I'd probably pull the engine and do the upside down thing if the kerosene and magnet rod didn't work. It will be a pain though.
