I just don't understand the factory. I thought under the new management team, that they would be bending over backwards for customer satisfaction. There should be no reason why an experienced dealer like RPM, or whatever they are now called, should not be able to do the mods for you.
I understand your frustration!
Both my dealer in Toulouse and its partner company (nearer to my home, where I plan to have servicing done) are involved in racing. They know what they are up to. If this factory-fitting requirement is confirmed, it will annoy a lot of people...
