I suggested chain drive a couple of years ago and got soundly shot down in flames! Knowing David G and his Motorsport engineering background, he certainly knows what he is talking about and I'm looking forward to the moment he does it.
I'm with Jays on this:
Modern "X" ring chains kept clean with a Scott Oiler have a life of, well who knows? I did nearly 30,000 miles on my 1050 Tiger and the chain was still in specification when I sold it. That engine puts out more power than the S&S motor and almost as much torque, but as an in-line 3 the torque is more smoothly spread.
