...and yes I even heated up the set screw. It is not budging one bit!
If the head is buggered try jamming a torx bit in it to loosen after penetrant and heat.
I had difficulty removing the screw on my Stelvio, and to have spares sourced a pack of 50 very cheaply from a Chinese vendor.Gave half of them to the local Guzzi specialist, but still have plenty. If you don't mind the wait for the mail from Western Australia, pm me your address and I'll send a couple, free to a deserving home.cheers, Fred
