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.

CSC kit - is this a HD CSC or the CSC Eliminator?

How did you adjust it when trying to resolve this?
Specifically what AFP setting did you have to start?
What AFP setting did you adjust it down to?
How high was the friction point off the floor initially?
How high did you go in testing?

I would setup the AFP to 0% (Knob fully clockwise until the plates retract fully towards you) This will be same as the stock pedal assembly for stroke. Next adjust it to a high friction point like stock. Does it still cause the same issue setup this way?
If so you will have the same problem with the stock pedal and its likely a problem with the clutch itself, MC or CSC.

If not then start from 0% and increase the AFP setting 10% at a time until you find the maximum your clutch can handle while also lowering the friction point a little each time.

I'm guessing there is something else going on with your clutch setup as in my experience 99% of people with a Twin plate clutch can typically run a full 100% AFP and a pretty low engagement without running into the issues your describing.
