MK1. Well, not really vibration, it doesn't shake. It has been reassembled after inspection, with new rods, and travelled 50 miles. I have only had it briefly up to 60mph, but at speeds over 50 my MK1 has a slight buzz, which is tolerable. I will expect to get pins and needles sensation in my hands. It is off the road now to re-torque the head and attend to the brakes. I have a few theories, but not having ridden a 4 before, what should I expect for the smoothest classic motorcycle ever?
