Use to have an M and had similiar problems. Probable reason for more loss when leaning to the right is return elevator dumping in a little more grain on the right side. Probable reason for loss to be worse going uphill is a slight reduction in engine rpm's due to pulling uphill and grain sliding over the sieves easier since angle is reduced going uphill. (you can probaly really fill her up when going downhill). Only thing I tried that had some success was to cut the fins off the rear corners of the chaffer. About the last 6 rows and in about 4 inches from the edge. helped quite a bit. Got the idea from JD as they were doing that on the 7720's and 8820's. They actually had removable sections made in their chaffers to remove for the problem you describe.
