I would recommend increasing the clutch rod setting a bit to raise the friction point a little at a time and test if that allows shifting under the same conditions. If not I would try reducing the AFP setting a bit as well to see if that makes the difference. The clutch isn't fully disengaging and causing some drag which is magnified at high RPM causing the gear lock outs.


Let me know how it goes.
