Thanks, Rob! Â I suspected it was you, but if it wasn't, then there truly is a ghost in the machine!
JPSpen - I've had only partial success re-using these crush washers - general theory is that it is best to have some around (they aren't expensive) as anytime I've had one start to leak on me, it cost me WAAY more time and $$ to repair the damage than the 15 cents or so for the washer.
YMMV
AS to the swingarm/driveshaft oil level, the BMW manuals indicate that if one sticks a small flat tip screw driver straightdown into the driveshaft fill hole on top, with the bike on its centerstand on a level surface, the oil level is correct if there is 1-2mm of oil on the tip of the screwdriver. Â It will not go down far into the hole before it contacts the driveshaft itself - the driveshaft should be just immersed in the oil at that point.
