When you have the clutch apart again have a DTI available and check the runout of the mainshaft at the clutch end, ie its side to side wobble not the endfloat. The mainshaft is long and has the large weight of the clutch on its unsupported end and can be bent by the forces, it was the failure mode of the production racers until they added an outrigger bearing. It may be that 70 mph is the point at which the wobble from side to side sends the clutch rod and clutch centre on an adventure.
