Yes G. O. All good points , what’s not to like ?
The only thing that comes to mind is that in the 1984 Nighthawk CB750SC was a bug in the design of the air box. Although not the 650 (didn't seem to have the problem), the 750 version was sensitive to strong freeway speed crosswind gusts. This was a dangerous symptom where the air intake weakened causing a rich fuel mix and a sudden loss of power. Conversely, when the vacuum in the air box normalized, then the rider would experience a sudden surge (restoration) in power.

I used to experience on my 4cyl Honda 250 very often, actually there is a lagoon here which used to be a part of my daily commute and every single time as I would come into this long left curve upon entry I would always get hit by a crosswind for a few hundred meters where I'd experience a sudden loss of power and then a surge, usually 2-3 of these "hick-ups" and as soon as I'd line up with the lagoon and the wind which would then be chest wind, the bike would just run perfectly normal. I asked a few mechanics I used to visit at that time, they'd check the bike out and tell me all is well and never offer an explanation. And now more than a decade later I get it from a random GO fact hole

I experienced something similar a long while ago, crossing one of the bridges on Highway 1 south of Big Sur. I was riding a 1990 Katana 750 with the fully enclosed bodywork. The onshore crosswinds were severe, but inconsistent. Sometimes I was leaned over at least 45 degrees, then it would let up and I was suddenly be in the oncoming lane (no traffic, but still frightening).
Other times there would be a sudden strong gust that apparently sucked the air out of the airbox, and the engine died as if I had cut off the engine. It would restart pretty quickly, but it has caused me to shy away from faired bikes (and that road section).
