that year model has a "recall" or case by case fix on the shifter fork assy.
they will supply you with a stronger plate and spring, plus bolts already loctited.
this is because sometimes the shifter tabs bend and that will make it hard to shift/find neutral and will happen without previous notice so if the cluth has no air in the line and your shifter is propertly adjusted as the above fellow ducatistas stated I would consider poping out the lh engine cvr to check into the fork alignment and tabs condition.
