If you look at valve cover portion that is just forward of the spark plugs, each side (left and right side of the bike) has two dowels that are close together. You should be able to see if the o-ring is in there, or at least if all four dowels look the same.
If the o-ring lands in the right place, it will just be along for the ride and you'll find it next time you take the cover off. It could end up getting ground up by moving parts, or falling down an oil return passage. Neither would be fatal damage, but it's not supposed to be there. I'd see if you can account for all four without taking anything apart. If you think one has gone astray, be sure to look around the spark plug bases closely, too. Several little moisture drain holes there that could catch one if it fell outside the engine.
