I will attempt to answer the first part of your question Pete - about the Patron Saint- his name is Paul Bezilla and he lives in Winnepeg, Manitoba, Canada. I bought my first B2 off him about 11 years ago. I tried contacting him several years ago about some parts and he wasn't very interested as I think he sold his bike- altho at the time he had about 5.
His bike was a modified B2 , he enlarged the already large euro tank, fitted a fuel cell to the rear carrier rack and did alot of " how far can you ride in 24 hours " type of riding.
He'd fitted the oil cooler and two piston caliper mod to the front disc brake. And then all that knowledge disappeared quite rapidly. But that would have been a high mileage bike alright.
Larry Colin on the old forum had more than 150,000 miles on his bike - he was by far the highest mileage bike here in North America that I have heard of. So that is about 241,000 km in your money- not as good as some of these others
