On a F2 -late model - the small pulley will get on up around 1100 + . Remember capacity is usually greatest at highest speed but also that 'speed cracks'. Run the RPM up as fast as possible til she starts to crack grain then back her off a few revs til sample is acceptable. Wheat with a spike is OK if you are talking soft red winter wheat as it is easy to shell. The 3d and 4th row of add-in spike bars will really help shell out those hard to get out kernals. Cyl clearence should be about 1_8 " If one has some spike teeth that are bent and "clicking" remember this is '0' clearance and can result in cracking. That is what that funny looking tool is for hanging on the side of the elevator. Straighting spike teeth , a fun job right up there with pulling tobacco suckers, if you know what I mean.
