Oh no John, really sorry to hear about this. That bike was about as clean and solid an example as you could hope for, which is why we both bought it, so even more of a blow when that happens, and as you said, you avoided an 8v for this very fear. I'm pretty sure it's nothing I did in my ownership as I only had to do minimal usual maintenance and one rocker cover gasket replacement I seem to recall (but apologies if it was somehow?) and the guy I bought it from was fastidious too, so that's really bad luck for you. And the garage just compounded the problem. I hope you enjoyed those 7 months with it though. Are you going to get another, or stick with the LeMans. That should be a satisfying rebuild when you've completed it. Be good to see it when it's done.
