If you have the extended Sunnybrook you may want to install some thick filler bars to prevent to much overthreshing. Hopefully you have the stacked or channel helicals. No reverse bars would likely help. You need great accelerator rolls and some run a canola board. That is a 3 or 4" board fastened to rear frame of chaffer to act as a dam. I have heard of some guys cutting first few louvers of chaffer loose from main control and standing them up as straight as posible. Good luck
