Having no experience of the rotor setup on the RSV,
I am guessing that it must differ from the 1125 rotor.
On the 1125 rotor there is minimal clearance between the back of the rotor and the casing, which is why the 'oil jet Rotor' wins, by directing an oil stream onto the stator coils.
I doubt the 'RSV's oil jet remedy' spraying on the solid rotor assembly of an 1125
would have any cooling effect on the stator temp
Think the RSV must have a vented rotor, thereby allowing oil mist/stream to contact the stator and increase cooling

White 09 1125R with fairing, Oil jet rotor, no issues
