I am assuming you are cutting wheat, wide space bars are not the best but in an M2 I would run the cylinder above 1150 or 1200, at this speed it is 1_2 the engine speed, took a lot of horsepower. Run as many rasp bars as needed to get the crop from the heads, at least 3 to 4 and I think you can go to 5 in the F. Clearance 5_16 to 3_8 depending how much straw you take in, which at times more straw will separate better but takes more power in the cylinder. Does you concave door have rasp bars that are wornIJ if so replace them. SeiveIJ I always ran so the front of the box was lower than the back. Good luck
