I think he is saying that hex head shaft would fix the engagement in the front but it is impossible to use it because it can not be made to fit the rest of the geometry in the transmission (even with cutting)
And the 1150 6 speed (and 1100 6 speed, 1100S) and some other chromeheads are the only BMW's in the history of BMW (not only bikes) and clutches (in general) that do not have full spline hub engagement. But I am still young, maybe I haven't seen enough.
