In my collection I own the V11, just bought a 74 Eldorado, and have owned the R90/6 for 20 years. Love them all, don't see it being fair to compare the V11 with the /6 totally different time of production.
To compare the Eldorado to the /6 is a more direct comparison. The Eldo is a cooler bike,but which one has an oil filter,which one has an alternator vs a generator .Like I said love them both,but in some ways the /6 is probably a more advanced, reliable machine, and the parts new and used are easier to come by.
Hopefully some one will bring this one back from the dead and turn it into a bobber that seem to be so popular these days.
But as it sits,it's a $200 parts bike, just my 2 cents.
