I just got it in the mail today, too... First thing I read!
I could have sworn one of the mags got the 2G B12 up to an honest 156 mph, so I was a little surprised by the 150 comment. Would have thought it'd be a little faster than that.
With my lardass on it, I've had mine up to just shy of an
indicated 160 before I ran out of real estate and had to slow down for a curve. And we know the stock speedo is optimistic.
(Closed course, of course... I'd never do that on a public road.)
