Reading some recent comments i am now thinking my breather oil excess could be caused by my eagerness to get up to cruising speed. Too much right hand (that's for you GB)

I find vibes start around 50. They don't get worse, but neither do they go away despite revving it as high as I dare (old engine, alloy rods, .....). Usually engines have a 'period' where vibration starts and then goes away again, but mine doesen't. Shame, as I enjoy a fistful of throttle whenever possible. And so I stay under that - vibes aren't intolerable, but make you want to get back to the smooth-as-silk area.

'Capable of pushing the speedometer needle round to 85mph: of cruising comfortably in the region of 70mph, so long as road conditions permit...'Motor Cycling July 1954. Test of 500 A7.

Th Motor Cycle in May 1956 managed to wring 86mph out of an A7....in third! Scary thought. I wonder what the vibes were like? They got a timed 90mph in top.

The brakes were described as, 'smoooth and powerful.' Different expectations methinks.
