Hm, I'd give it a 7.
Felt like he isn't used to Bullets, or had one unlike ours? Anyhow there were some issues:
He reported a lack of power between 1000 and 1500 rpm causing engine to flame out. I can ride out from stop without having to rev; idle is strong enough to get started and even ride figures. In fact any bike can do that.
He complained of uncomfortable vibration above 4000 rpm and headwobble at 130 kph. That's not regular and should be looked into and fixed.
Beyond that: he rode a nice bike and got good pictures made. Such a well documented review is rare, kudos.
