Hello Giovanni,
Thanks for following up, I am glad that you care so much about your customers. This weekend I did about 500KM of riding and alot of it was between 3 - 5K RPM (great testing the exhaust valve) and I did not have a single problem. It looks like it is all fixed now!
I want to bring it to you for the service from now on.
Let me know,
Grazie!
Jan-Michael
