Your right in that you need to run rotor slow enough to eliminate cracking. To slow with rotor will at some point start taking more power and sluging may be noted. You have to get complete thresh before letting material threw concave when you don't have tailings return package. You'll need more filler bars and or closer concave clearance with to do better job. Get header to work better so you can pack more material into concave. Crop rubbing out crop should cause the least damage. I understand your thinking on reverse bars but don't think you'll notice a hole lot of difference with or without them. like others have said you should extend your second helical from gearbox over feeder corner, extend cylinder bars and a few other things but you get her feed nice to start with and go on from there. It might be time to do some rebuilding in cylinder area anyway and that would be a good time to do some hyperizing. As far as air filter warning I would change both filters no matter how they look and then replace sending unit if still bothering. As far as your short straw problem you should check area of rear feed door and area in front of concave to see nothing is leaking there and coming in threw seperator fan.
