V85TT pinking

Morning all
Just a heads up for anyone who may have experienced a ‘pinkin’ noise under engine load.
My first V85 started to experience it after about 15,000 fully serviced miles, and my new Centenareo developed the same issue after only 1,000 miles.
Took it back into Teasdales who have diagnosed an issue with the valve guides (incorrectly drilled in factory) allowing pre ignition to take place.
Teasdales were very helpful (as always) and have replaced the cylinder head under warranty.
If anyone is experiencing this,its worth getting it checked out, as it seams to lead to valve seat burn out
Other than that, what a great bike
Regards from Cumbria
