Driveline vibration elimination (hopefully!)

El Toro, de hecho.

No update, because I solved the problem by buying a 2013 K1600GTL 'El Toro' that effortlessly and with 0 vibrations carries me like on a magic carpet the 122 miles to Los Angeles in the morning (and of course 122 miles back in the afternoon). So, have had less incentive to work on the C650, since I wanted to give the K1600 a full service and I had some 'honey do' list things to also take care of. Next is a fairly extensive service on our daily driver Mercedes GLK but shortly after that I should be able to make time to swap out one of the rear bearings that may be causing my little bit of play in the rear wheel. Also I was noticing my rear tire is getting to the end of its useful life and getting a quality new one might help as well. I will post updates once I have replaced the bearing and later the tire. It's bound to be one of these two things, having exhausted other usual suspects. I don't think the current tire is worn like you describe, but I will check in the daylight, tomorrow. Thanks for your suggestions.

How much has the chain has run, and what size of chain guides you have installed?

A falta de hacer una prueba a fondo, creo que solucionó el problema de las vibraciones. El rodamiento de la tapa que va acoplado al eje del variador tenía una bola rota y mucho juego. He hecho cambiar los dos rodamientos de la tapa, que ya estaban estropeados con sólo 28.000K. Si vas con pasajero y top case, como es mi caso, pon toda la precarga en el muelle del amortiguador para que no baje tanto con el peso y se aligere el tren delantero.

Englis translation:
"Without doing a thorough test, I think the vibration problem has been solved. The bearing on the cover that is coupled to the variator shaft had a broken ball and a lot of play. I have had both bearings on the cover changed, which were already damaged with only 28,000K. If you are going with a passenger and a top case, as is my case, put all the preload on the shock absorber spring so that it does not drop so much with the weight and the front end is lightened."
