I would simply remove the reverse bars and leave the spot blank. Add an F2 bar (pictured with part n in Hyper Mods) to the belly of the cage where your two blank spots are on the rotor. You'll definately want to add the helical over the feeder opening and extend helicals into discharge. This will promote smooth, even flow of material through the cage. The blank spots where your reverse bars used to be, in combination with the F2 bar on cage belly, will allow crop to be "tripped up" and flipped over to release kernals of grain that may have been trapped. These few mods will really make a difference in how your combine performs and are dirt cheap to do. The best thing is it is all reversable in the rare case that you are not pleased with the results. Best of luck and let us know what you do and the results! Tom langan
