I understand. I only had this issue with the 107 and the 110. I think it is because there might be a hiccup somewhere in the bottom end as it ramps up to the higher RPM. This was not an issue with the 312 or 323. I believe this is also due to the 107 and 110 have more power and rpm up top and less on the bottom end.
